1. Reciprocal/interactive play with the therapist is embedded into the music. 2. Two clients (or more, if being doubled) may take turns playing, listen/wait at times, and then play together at the end. 3. Written in the key of A major, added tones such as the Maj 7, min 7, Maj 9th, #11ths and b5 are used to enrich the chords and lend a jazzy style to the piece. 4. In addition to the primary chords of I (A), IV (D) and V7 (E7), minor chords such as iii (c#m7), vi (f#m7), and-a chord out of the key-the bII (Bb Maj9 b5) are present. 5. Notice the alternation of wide and close spacing between notes in the piano arrangement. Using contrasts can invite and hold attention. 3) “Reed Horn Blues” by Marc Houde Instrumental compositions can be written with simultaneous parts leading players into directed ensemble playing. The following 4-measure excerpt from a piece by Marc Houde invites players to make music with two reed horns, electric guitar (open D tuning), percussion and cymbal. It can be found in Composition and Improvisation Resources for Music Therapists, edited by Colin Andrew Lee, Aimee Berends, and Sara Pun (Barcelona Publishers, 2015). The composer writes: My youngest private music production student is a kid named Ilan. He makes moody trip-hop and deep house using Ableton Live. For our session today, Ilan came in with a downtempo, jazzy hip-hop instrumental. I helped him refine and polish it, and then we talked about his ideas for what kind of vocal might work on top. He wanted an emcee to flow over it, so I gave him my folder of hip-hop acapellas I’ve collected. The first one he tried was “Fu-Gee-La [Refugee Camp Remix]” by the Fugees. I had it all warped out already, so all he had to do was drag and drop it into his session and press play. It sounded great, so he ran with it. Here’s what he ended up with: At this point, let me clarify something. To his knowledge, Ilan had never heard “Fu-Gee-La” before using it in his track. His first exposure was the acapella over his own instrumental. His track is quite a bit faster than the original (well, technically, it’s slower, but the kids these days like their rapping doubletime.) Also, we needed to pitch the acapella down a minor third to match the key of Ilan’s instrumental. As of this writing, he has heard his remix about a thousand more times than the original. And now, let’s consider the Fugees’ “original” song. Ilan used the acapella from a remix, not from the original original, which makes a difference since the remix has some different lyrics. The Fugees’ original original is not itself totally original. It contains several samples, including liberal interpolations of Teena Marie, and a quote from “Shakiyla (JRH)” by Poor Righteous Teachers, which itself contains several samples. Hip-hop’s sampling culture was still radical back in the 90s when “Fu-Gee-La” was released, but has since become absorbed into mainstream sensibilities. Ilan is ambitious and talented, but his sensibilities are well in keeping with most of his millennial peers. So it’s worth looking into his norms and values around authorship and ownership. During our session, he was interested in the Fugees song simply as raw material for his own creativity, not as a self-contained work that needed to be “appreciated” first (or ever.) Ilan’s concerns about where he sources his sounds comes down one hundred percent to expediency. He buys sounds from the Ableton web site because that’s easy. The same goes for buying tracks from iTunes, if they surface with a quick search. Otherwise Ilan just does YouTube to mp3 conversion. I’ve never heard him voice any concern about the idea of intellectual property, or any desire to seek anyone’s permission. So here we have a young musician who created an original track, and then after the fact layered in a commercially released hip-hop vocal track on a whim. If that one hadn’t worked, he would have just dropped in another one chosen more or less at random. This kind of effortless drag-and-drop remixing requires some facility with Ableton Live, which is expensive and has a learning curve. But this practice is easier than it was five years ago, and is only going to get easer. Music educators: are we ready for a world where this kind of creativity is so accessible? Rights holders: do you know just how little the kids know or care about the concept of musical intellectual property? And musicians: have you experienced the pleasure and inspiration of freely mixing your ideas with everyone else’s? This is a crazy time we live in. We created the Groove Pizza to make it easier to both see and hear rhythms. The next step is to create learning experiences around it. In this post, I’ll use the Pizza to explain the structure of some quintessential funk and hip-hop beats. You can click each one in the Groove Pizza, where you can customize or alter it as you see fit. I’ve also included Noteflight transcriptions of the beats. The Backbeat Cross View in Noteflight This simple pattern is the basis of just about all rock and roll: kicks on beats one and three (north and south), and snares on beats two and four (east and west.) It’s boring, but it’s a solid foundation that you can build more musical-sounding grooves on top of. The Big BeatView in Noteflight This Billy Squier classic is Number nine on WhoSampled’s list of Top Ten Most Sampled Breakbeats. There are only two embellishments to the backbeat cross: the snare drum hit to the east is anticipated by a kick a sixteenth note (one slice) earlier, and the kick drum to the south is anticipated by a kick an eighth note (two slices) earlier. It isn’t much, but together with some light swing, it’s enough to make for a compelling rhythm. The groove is interestingly close to being symmetrical on the right side of the circle, and there’s an antisymmetry with the kick-free left side. That balance between symmetry and asymmetry is what makes for satisfying music. Planet Funk (eighth notes)View in Noteflight This pattern reminds me of Saturn viewed edge-on. The hi-hats are the planet itself, the snares are the rings, and the lone kick drum at the top is a moon. To make the simplest funk beats, all you need to do is add more moons into the kick drum orbit. It’s A New DayView in Noteflight The Skull Snaps song isn’t too well known, but the break that kicks it off is number five on the WhoSampled list. The Planet Funk template has some extra kick drums embellishing particular beats. The kick on the downbeat (the topmost slice) has a kick anticipating it a sixteenth note (one slice) earlier, and another following it an eighth note (two slices) later. The snare drum hit to the west is anticipated by two more kicks. All that activity is balanced by the southeast half of the pizza, which is totally kick-free. Like “The Big Beat,” “It’s A New Day” is close to being symmetrical, with just enough variation to keep it interesting. When The Levee BreaksView in Noteflight This Led Zeppelin classic embodies the awesome majesty of rock. Rhythmically, though, it has more in common with funk. The crucial difference is beat three, the southernmost point on the pizza. In rock, you usually have a kick there. In funk, you usually don’t. The Levee break has a kick a sixteenth note before beat three, which is quite a surprise. Try moving that kick a slice later, and you’ll hear the groove lose its tension and interest. Like “It’s A New Day,” the Levee break sets up the second snare hit with two kicks. There’s another interesting wrinkle, too, a kick that immediately follows the first one. The result is another symmetrically asymmetrical drum pattern. Planet Funk (sixteenth notes)View in Noteflight If you put a hi-hat on every slice of the pizza, you get a busier version of the basic funk groove. With twice as many hi-hats, you can slow the tempo down and still have an energetic feel. So Fresh, So CleanView in Noteflight This OutKast banger has a fascinating drum machine pattern. The snare and hi-hat stick to the Planet Funk pattern above, but against all this predictable symmetry, the kick drum is all over the place. To understand what’s going on here, you need to know something about the concept of strong and weak beats. Strong beats are where you expect drum hits to fall, and weak beats are where you don’t expect them. The more times you have to divide the circle in half to get to a given beat, the weaker it is. The weakest beats are the even-numbered pizza slices. In the first bar, pictured above, every single even-numbered slice has a kick on it. This is, to put it mildly, not typical. Usually the base of your beat is stable and predictable, and the higher-pitched ornaments are more unpredictable. That’s what makes “So Fresh, So Clean” so cool. Nas Is LikeView in Noteflight While this track is best known for its samples, and deservedly so, the underlying drum machine rhythm is pretty remarkable too. Like the OutKast song above, the snares and hi-hats are mostly stable, with most of the variation in the kick. I won’t verbally analyze all four bars of the pattern, but if you play with it, you’ll see the idea of balanced symmetry and asymmetry at work. Amen BreakView in Noteflight The Amen break is the most complex rhythm here, and it’s a post unto itself to really explain the whole thing. The important thing is to compare the simplicity of the hi-hatsadditional sound, an open hi-hat in the last bar. Displacement! I use a project-based approach to teaching music technology. Technical concepts stick with you better if you learn them in the course of making actual music. Here’s the list of projects I assign to my college classes and private students. I’ve arranged them from easiest to hardest. The first five projects are suitable for a beginner-level class using any DAW–my beginners use GarageBand. The last two projects are more advanced and require a DAW with sophisticated editing tools and effects, like Ableton Live. If you’re a teacher, feel free to use these (and let me know if you do). Same goes for all you bedroom producers and self-teachers. The projects are agnostic as to musical content, style or genre. However, the computer is best suited to making electronic music, and most of these projects work best in the pop/hip-hop/techno sphere. Experimental, ambient or film music approaches also work well. Many of them draw on the Disquiet Junto. Enjoy. LoopsAssignment: Create a song using only existing loops. You can use these or these, or restrict yourself to the loops included with your DAW. Do not use any additional sounds or instruments. For beginners, I like to separate this into two separate assignments. First, create a short (two or four bar) phrase using four to six instrument loops and beats. Then use that set of loops as the basis of a full length track, by repeating, and by having sounds enter and exit. Concepts:
Hints:
MIDIAssignment: Create a piece of music using MIDI and software instruments. Do not record or import any audio. You can use MIDI from any source, including: playing keyboards, drum pads or other interfaces; drawing in the piano roll; importing scores from notation programs; downloading MIDI files from the internet (for example, from here); or using the Audio To MIDI function in your DAW. I don’t treat this as a composition exercise (unless students want to make it one.) Feel free to use an existing piece of music. The only requirement is that the end result has to sound good. Simply dragging a classical or pop MIDI into the DAW is likely to sound terrible unless you put some thought into your instrument choices. If you do want to create something original, try these compositional prompts. Concepts:
Hints:
Found soundAssignment: Record a short environmental sound and incorporate it into a piece of music. You can edit and process your found sound as you see fit. Variation: use existing sounds from Freesound. Concepts:
Hints:
Peer remixAssignment: Remix a track by one of your classmates (or friends, or a stranger on the internet.) Feel free to incorporate other pieces of music as well. Follow your personal definition of the word “remix.” That might mean small edits and adjustments to the mix and effects, or a radical reworking leading to complete transformation of the source material. There are endless variations on the peer remix. Try the “metaremix,” where students remix each others’ remixes, to the nth degree as time permits. Also, do group remix activities like Musical Shares or FX Roulette. Concepts:
Hints:
Self remixAssignment: Remix one of your own projects, using the same guidelines as the peer remix. This is a good project for the end of the semester/term. Song transformationAssignment: Take an existing song and turn it into a new song. Don’t use any additional sounds or MIDI. Concepts:
Hints:
Shared sampleAssignment: Take a short audio sample (five seconds or less) and build a complete piece of music out of it. Do not use any other sounds. This is the most difficult assignment here, and the most rewarding one if you can pull it off successfully. Concepts:
Hints:
Writing assignmentsI like to have students document their process in blog posts. I ask: What sounds and techniques did you use? Why did you use them? Are you happy with the end result? Given unlimited time and expertise, what changes would you make? Do you consider this to be a valid form of musical creativity? This semester I also asked students to write reviews of each others’ work in the style of their preferred music publication. In the future, I plan to have students write a review of an imaginary track, and then assign other students to try to create the track being described. The best way to learn how to produce good recordings is to do critical listening exercises. I assign students to create musical structure and space graphs in the spirit of William Moylan. Further challengesThe projects above were intended to be used for a one-semester college class. If I were teaching over a longer time span or I needed more assignments, I would draw from the Disquiet Junto, Making Music by Dennis DeSantis, or the Oblique Strategies cards. Let me know in the comments if you have additional recommendations. The Groove Pizza is a playful tool for creating grooves using math concepts like shapes, angles, and patterns. Here’s a beat I made just now. Try it yourself!
This post explains how and why we designed Groove Pizza. What it does The Groove Pizza represents beats as concentric rhythm necklaces. The circle represents one measure. Each slice of the pizza is a sixteenth note. The outermost ring controls the kick drum; the middle one controls the snare; and the innermost one plays cymbals. Connecting the dots on a given ring creates shapes, like the square formed by the snare drum in the pattern below. The pizza can play time signatures other than 4/4 by changing the number of slices. Here’s a twelve-slice pizza playing an African bell pattern. You can explore the geometry of musical rhythm by dragging shapes onto the circular grid. Patterns that are visually appealing tend to sound good, and patterns that sound good tend to look cool. Herbie Hancock did some user testing for us, and he suggested that we make it possible to show the interior angles of the shapes. Groove Pizza HistoryThe ideas behind the Groove Pizza began in my masters thesis work in 2013 at NYU. For his NYU senior thesis, Adam November built web and physical prototypes. In late summer 2015, Adam wrote what would become the Groove Pizza 1.0 (GP1), with a library of drum patterns that he and I curated. The MusEDLab has been user testing this version for the past year, both with kids and with music and math educators in New York City. In January 2016, the Music Experience Design Lab began developing the Groove Pizza 2.0 (GP2) as part of the MathScienceMusic initiative. MathScienceMusic Groove Pizza Credits:
The learning opportunityThe goals of the Groove Pizza are to help novice drummers and drum programmers get started; to create a gentler introduction to beatmaking with more complex tools like Logic or Ableton Live; and to use music to open windows into math and geometry. The Groove Pizza is intended to be simple enough to be learned easily without prior experience or formal training, but it must also have sufficient depth to teach substantial and transferable skills and concepts, including:
Marshall (2010) recommends “folding musical analysis into musical experience.” Programming drums in pop and dance idioms makes the rhythmic abstractions concrete. Visualizing rhythmWestern music notation is fairly intuitive on the pitch axis, where height on the staff corresponds clearly to pitch height. On the time axis, however, Western notation is less easily parsed—horizontal space need not have any bearing at all on time values. A popular alternative is the “time-unit box system,” a kind of rhythm tablature used by ethnomusicologists. In a time-unit box system, each pulse is represented by a square. Rhythmic onsets are shown as filled boxes. Nearly all electronic music production interfaces use the time-unit box system scheme, including grid sequencers and the MIDI piano roll. A row of time-unit boxes can also be wrapped in a circle to form a rhythm necklace. The Groove Pizza is simply a set of rhythm necklaces arranged concentrically. Circular rhythm visualization offers a significant advantage over linear notation: it more clearly shows metrical function. We can define meter as “the grouping of perceived beats or pulses into equivalence classes” (Forth, Wiggin & McLean, 2010, 521). Linear musical concepts like small-scale melodies depend mostly on relationships between adjacent events, or at least closely spaced events. But periodicity and meter depend on relationships between nonadjacent events. Linear representations of music do not show meter directly. Simply by looking at the page, there is no indication that the first and third beats of a measure of 4/4 time are functionally related, as are the second and fourth beats. However, when we wrap the musical timeline into a circle, meter becomes much easier to parse. Pairs of metrically related beats are directly opposite one another on the circle. Rotational and reflectional symmetries give strong clues to metrical function generally. For example, this illustration of 2-3 son clave adapted from Barth (2011) shows an axis of reflective symmetry between the fourth and twelfth beats of the pattern. This symmetry is considerably less obvious when viewed in more conventional notation. The Groove Pizza adds a layer of dynamic interaction to circular representation. Users can change time signatures during playback by adding or removing slices. In this way, very complex metrical shifts can be performed by complete novices. Furthermore, each rhythm necklace can be rotated during playback, enabling a rhythmic modularity characteristic of the most sophisticated Afro-Latin and jazz rhythms. Exploring rotational rhythmic transformation typically requires very sophisticated music-reading and performance skills to understand and execute, but doing so is effortlessly accessible to Groove Pizza users. Visualizing swingWe traditionally associate swing with jazz, but it is omnipresent in American vernacular music: in rock, country, funk, reggae, hip-hop, EDM, and so on. For that reason, swing is a standard feature of notation software, MIDI sequencers, and drum machines. However, while swing is crucial to rhythmic expressiveness, it is rarely visualized in any explicit way, in notation or in software interfaces. Sequencers will sometimes show swing by displacing events on the MIDI piano roll, but the user must place those events first. The grid itself generally does not show swing. The Groove Pizza uses a novel (and to our knowledge unprecedented) graphical representation of swing on the background grid, not just on the musical events. The slices alternately expand and contract in width according to the amount of swing specified. At 0% swing, the wedges are all of uniform width. At 50% swing, the odd-numbered slice in each pair is twice as long as the following even-numbered slice. As the user adjusts the swing slider, the slices dynamically change their width accordingly. Our swing visualization system also addresses the issue of whether swing should be applied to eighth notes or sixteenths. In the jazz era, swing was understood to apply to eighth notes. However, since the 1960s, swing is more commonly applied to sixteenth notes, reflecting a broader shift from eighth note to sixteenth note pulse in American vernacular music. To hear the difference, compare the swung eighth note pulse of “Rockin’ Robin” by Bobby Day (1958) with the sixteenth note pulse of “I Want You Back” by the Jackson Five (1969). Electronic music production tools like Ableton Live and Logic default to sixteenth-note swing. However, notation programs like Sibelius, Finale and Noteflight can only apply swing to eighth notes. The Groove Pizza supports both eighth and sixteenth swing simply by changing the slice labeling. The default labeling scheme is agnostic, simply numbering the slices sequentially from one. In GP1, users can choose to label a sixteen-slice pizza either as one measure of sixteenth notes or two measures of eighth notes. The grid looks the same either way; only the labels change. Drum kitsWith one drum sound per ring, the number of sounds available to the user is limited by the number of rings that can reasonably fit on the screen. In my thesis prototype, we were able to accommodate six sounds per “drum kit.” GP1 was reduced to five rings, and GP2 has only three rings, prioritizing simplicity over musical versatility. GP1 offers three drum kits: Acoustic, Hip-Hop, and Techno. The Acoustic kit uses samples of a real drum kit; the Hip-Hop kit uses samples of the Roland TR-808 drum machine; and the Techno kit uses samples of the Roland TR-909. GP2 adds two additional kits: Jazz (an acoustic drum kit played with brushes), and Afro-Latin (congas, bell, and shaker.) Preset patterns automatically load with specific kits selected, but the user is free to change kits after loading. In GP1, sounds can be mixed and matched at wiell, so the user can, for example, combine the acoustic kick with the hip-hop snare. In GP2, kits cannot be customized. A wider variety of sounds would present a wider variety of sonic choices. However, placing strict limits on the sounds available has its own creative advantage: it eliminates option paralysis and forces users to concentrate on creating interesting patterns, rather than struggling to choose from a long list of sounds. It became clear in the course of testing that open and closed hi-hats need not operate separate rings, since it is not desirable to ever have them sound at the same time. (While drum machines are not bound by the physical limitations of human drummers, our rhythmic traditions are.) In future versions of the GP, we plan to place closed and open hi-hats together on the same ring. Clicking a beat in the hi-hat ring will place a closed hi-hat; clicking it again will replace it with an open hi-hat; and a third click will return the beat to silence. We will use the same mechanic to toggle between high and low cowbells or congas. Preset patternsIn keeping with the constructivist value of working with authentic cultural materials, the exercises in the Groove Pizza are based on rhythms drawn from actual music. Most of the patterns are breakbeats—drums and percussion sampled from funk, rock and soul recordings that have been widely repurposed in electronic dance and hip-hop music. There are also generic rock, pop and dance rhythms, as well as an assortment of traditional Afro-Cuban patterns. The GP1 offers a broad selection of preset patterns. The GP2 uses a smaller subset of these presets. Breakbeats
Afro-Cuban
Pop
Hip-hop
Rock
Jazz
Mathematical applicationsThe most substantial new feature of GP2 is “shapes mode.” The user can drag shapes onto the grid and rotate them to create geometric drum patterns: triangle, square, pentagon, hexagon, and octagon. Placing shapes in this way creates maximally even rhythms that are nearly always musically satisfying (Toussaint 2011). For example, on a sixteen-slice pizza, the pentagon forms rumba or bossa nova clave, while the hexagon creates a tresillo rhythm. As a general matter, the way that a rhythm “looks” gives insight into the way it sounds, and vice versa. Because of the way it uses circle geometry, the Groove Pizza can be used to teach or reinforce the following subjects:
Specific kinds of music can help to introduce specific mathematical concepts. For example, Afro-Cuban patterns and other grooves built on hemiola are useful for graphically illustrating the concept of least common multiples. When presented with a kick playing every four slices and a snare playing every three slices, a student can both see and hear how they will line up every twelve slices. Bamberger and diSessa (2003) describe the “aha” moment that students have when they grasp this concept in a music context. One student in their study is quoted as describing the twelve-beat cycle “pulling” the other two beats together. Once students grasp least common multiples in a musical context, they have a valuable new inroad into a variety of scientific and mathematical concepts: harmonics in sound analysis, gears, pendulums, tiling patterns, and much else. In addition to eighth and sixteenth notes, GP1 users can also label the pizza slices as fractions or angles, both Cartesian and polar. Users can thereby describe musical concepts in mathematical terms, and vice versa. It is an intriguing coincidence that the polar angle π/16 represents a sixteenth note. One could go even further with polar mode and use it as the unit circle on the complex plane. From there, lessons could move into powers of e, the relationship between sine and cosine waves, and other more advanced topics. The Groove Pizza could thereby be used to lay the ground work for concepts in electrical engineering, signal processing, and anything else involving wave mechanics. Future workThe Groove Pizza does not offer any tone controls like duration, pitch, EQ and the like. This choice was due to a combination of expediency and the push to reduce option paralysis. However, velocity (loudness) control is a high-priority future feature. While nuanced velocity control is not necessary for the artificial aesthetic of electronic dance music, a basic loud/medium/soft toggle would make the Groove Pizza a more versatile tool. The next step beyond preset patterns is to offer drum programming exercises or challenges. In exercises, users are presented with a pattern. They may alter this pattern as they see fit by adding and removing drum hits, and by rotating instrument parts within their respective rings. There are restraints of various kinds, to ensure that the results are appealing and musical-sounding. The restraints are tighter for more basic exercises, and looser for more advanced ones. For example, we might present users with a locked four-on-the-floor kick pattern, and ask them to create a satisfying techno beat using the snares and hi-hats. We also plan to create game-like challenges, where users are given the sound of a beat and must figure out how to represent it on the circular grid. The Groove Pizza would be more useful for the purposes of trigonometry and circle geometry if it were presented slightly differently. Presently, the first beat of each pattern is at twelve o’clock, with playback running clockwise. However, angles are usually representing as originating at three o’clock and increasing in a counterclockwise direction. To create “math mode,” the radial grid would need to be reflected left-to-right and rotated ninety degrees. ReferencesAnkney, K.L. (2012). Alternative representations for musical composition.

I’m pleased to announce the second installment of Theory For Producers, jointly produced by Soundfly and the MusEDLab. The first part discussed the scales you can play on the black keys of the piano. This one talks about three of the scales you get from the white keys. The next segment will deal with four additional white-key scales. Go try it! If you’re a music educator or theory nerd, and would like to read more about the motivation behind the course design, read on. Some of my colleagues in the music teaching world are puzzled by the order in which we’re presenting concepts. Theory resources almost always start with the C major scale, but we start with E-flat minor pentatonic. While it’s harder to represent in notation, E-flat minor pentatonic is easier to play and learn by ear, and for our target audience, that’s the most important consideration. Okay, fine, the pentatonics are simple, it makes sense to start with them. But surely we would begin the white key part on the major scale, right? Nope! We start with Mixolydian mode. In electronica, hip-hop, rock, and pop, Mixolydian is more “basic” than major is. The sound of the flat seventh is more native to this music than the leading tone, and V-I cadences are rare or absent. I once had a student complain that the major scale makes everything sound like “Happy Birthday.” Our Mixolydian example, a Michael Jackson tune, was chosen to make our audience of producers feel culturally at home, to make them feel like we value the dance music of the African diaspora over the folk and classical of Western Europe. After Mixolydian, we discuss Lydian mode. While it’s a pretty exotic scale, we chose to address it before major because it’s more forgiving to improvise with–Lydian doesn’t have any “wrong” notes. In major, you have to be careful about the fourth, because it has strong functional connotations, and because it conflicts hard with the third. In Lydian, you can play notes in any order and any combination without fear of hitting a clunker. Also, exotic though it may be, Lydian does pop up in a few well-known songs, like in a recent Katy Perry hit. Finally, we do get to major, using David Bowie, and Queen. Even here, though, we downplay functional harmony, treating major as just another mode. Our song example uses a I-IV-V chord progression, but it runs over a static riff bassline, which makes it float rather than resolve. This class only deals with the three major diatonic modes. We’ll get to the minor ones (natural minor, Dorian, Phrygian and Locrian) in the third class. We debated doing minor first, but there are more of the minor modes, and they’re more complicated. We also debated whether or not to talk about chords. The chord changes in our examples are minimal, but they’re present. We ultimately decided to stick to horizontal scales only for the time being, and to treat chords separately. We plan to go back through all of the modes and talk about the chord progressions characteristic of each one. For example, with Mixolydian, we’ll talk about I-bVII-IV; with Lydian we’ll do I-II; and with major we’ll do all the permutations of I, IV, V and vi. Once again, we know it’s unconventional to deal with modes so thoroughly before even touching any chords, but for our audience, we think this approach will make more sense. Electronic music is not big on complex harmony, but it is big on modes. One of the challenges in creating Theory for Producers (or any online learning experience) is to build community. When you’re in a classroom with people, community emerges naturally, but on the web it’s harder. We’re using email to remind students to stay engaged over time, but we don’t want to end up in their spam folders. To make our emails welcome rather than intrusive, we decided to do Weekly Challenges, one-line prompts for music creation. Participants post their challenges in our SoundCloud group. I’ve been doing something similar with guitar students for a long time, in person rather than via email, for example with the one-note groove. In coming up with more prompts, I’ve been drawing on my recent foray into prose scores, inspired by the example of Pauline Oliveros. Really, you could think of my collection of prompts as very short and simple prose scores. Please feel free to use these, for yourself, for students, or for any other purpose. All I ask is that you drop me a line to tell me how you used them. The PromptsOne Note Groove: Create a melody using only one pitch. Two Note Groove: Create a melody using only two distinct pitches.

The first unit covered the black keys of the piano and the pentatonic scales. The next one will talk about the white keys and the diatonic modes. We were gathering examples, and we needed to find a well-known pop song that uses Lydian mode. My usual go-to example for Lydian is “Possibly Maybe” by Björk. But the course already uses a Björk tune for different example, and the Soundfly guys quite reasonably wanted something a little more millennial-friendly anyway. We decided to use Katy Perry’s “Teenage Dream” instead. A couple of years ago, Slate ran an analysis of this tune by Owen Pallett. It’s an okay explanation, but it doesn’t delve too deep. We thought we could do better. Here’s my transcription of the chorus: When you look at the melody, this would seem to be a straightforward use of the B-flat major scale. However, the chord changes tell a different story. The tune doesn’t ever use a B-flat major chord. Instead, it oscillates back and forth between E-flat and F. In this harmonic context, the melody doesn’t belong to the plain vanilla B-flat major scale at all, but rather the dreamy and modernist E-flat Lydian mode. The graphic below shows the difference. Both scales use the same seven pitches: B-flat, C, D, E-flat, F, G, and A. The only difference between the two is which note you consider to be “home base.” Let’s consider B-flat major first. To make chords from a scale, you pick any note, and then go clockwise around the scale, skipping every other degree. The chords are named for the note you start on. If you start on the fourth note, E-flat, you get the IV chord (the other two notes are G and B-flat.) If you start on the fifth note, F, you get the V chord (the other two notes are A and C.) In a major key, IV and V are very important chords. They’re called the subdominant and dominant chords, respectively, and they both create a feeling of suspense. You can resolve the suspense by following either one with the I chord. The weird thing about “Teenage Dream” is that if you think about it as being in B-flat, then it never lands on the I chord at all. It just oscillates back and fourth between IV and V. The suspense never gets resolved. If we think of “Teenage Dream” as being in E-flat Lydian, then the E-flat chord is I, which makes more sense. The function of the F chord in this context isn’t clearly defined by music theory, but it does sound good. Lydian is very similar to the major scale, with only one difference: while the fourth note of E-flat major is A-flat, the fourth note of E-flat Lydian is A natural. That raised fourth gives Lydian mode its otherworldly sound. The F chord gets its airborne quality from that raised fourth. Click here to play over “Teenage Dream” using the aQWERTYon. The two chords can be played on the letters Z-A-Q and X-S-W. For comparison, try playing it with B-flat major. Read more about the aQWERTYon here. “Teenage Dream” is not the only well-known song to use the Lydian I-II progression. Other high profile examples include “Dreams” by Fleetwood Mac and “Jane Says” by Jane’s Addiction. over the same chords. Try singing any of these songs over any of the others; they all fit seamlessly. The chorus of “Teenage Dream” uses a striking rhythm on the phrases “you make me”, “teenage dream”, and “I can’t sleep”. The song is in 4/4 time, like nearly all contemporary pop tracks, but that chorus rhythm has a feeling of three about it. It’s no illusion. The words “you” and “make” in the first line are each three eighth notes long. It sounds like an attempt to divide the eight eighth notes into groups of three. This rhythm is called Tresillo, and it’s one of the building blocks of Afro-Cuban drumming. Tresillo is the front half of son clave. It’s extraordinarily common in American vernacular music, especially in accompaniment patterns. You hear Tresillo in the bassline to “Hound Dog” and countless other fifties rock songs; in the generic acoustic guitar strumming pattern used by singer-songwriters everywhere; and in the kick and snare pattern characteristic of reggaetón. Tresillo is ubiquitous in jazz, and in the dance music of India and the Middle East. “Teenage Dream” alternates the Tresillo with a funky syncopated rhythm pattern that skips the first beat of the measure. When you listen to the line “feel like I’m livin’ a”, there’s a hole right before the word “feel”. That hole is the downbeat, which is the usual place to start a phrase. When you avoid the obvious beat, you surprise the listener, which grabs their attention. The drums underneath this melody hammer relentlessly away on the strong beats, so it’s easy to parse out the rhythmic sophistication. Katy Perry songs have a lot of empty calories, but they taste as good as they do for a reason. For his birthday, Milo got a book called Welcome to the Symphony by Carolyn Sloan. We finally got around to showing it to him recently, and now he’s totally obsessed. The book has buttons along the side which you can press to hear little audio samples. They include each orchestra instrument playing a short Beethoven riff. All of the string instruments play the same “bum-bum-bum-BUMMM” so you can compare the sounds easily. All the winds play a different little phrase, and the brass another. The book itself is fine and all, but the thing that really hooked Milo is triggering the riffs one after another, Ableton-style, and singing merrily along. Milo got primed to enjoy this book by two coincidental things. One is that in his preschool, they’ve been listening to Peter and the Wolf a lot, dancing to it, acting it out, etc. They use a YouTube video that shows both the story and the instruments side by side, so Milo has very clear ideas of what the oboe, clarinet, etc all look like and sound like. When he saw them in the orchestra book, he recognized them all immediately. The other thing is this weird computer animated cartoon called Taratabong, which is about anthropomorphic musical instruments. Milo has been watching it on YouTube a bunch, to the point of wanting me to pretend to be different characters and “talk” to him (which is an entertaining challenge for me–how do you have a conversation as a snare drum?) So Milo also recognizes different instruments in the orchestra book as Taratabong characters. Milo has now voluntarily watched a YouTube video of the entire first movement of Beethoven’s Fifth conducted by Leonard Bernstein, several times. That’s like nine minutes of classical music, which for a three-year-old is equivalent to nine hours. He sings along to all the riffs he recognized, announces each instrument as he sees it, and tells me about how Leonard Bernstein is Grandfather from Peter and the Wolf. I want to emphasize that we haven’t pushed him into any of this. If you read this blog, you know that I’m an outspoken anti-fan of Beethoven. We just put this stuff under Milo’s nose, and if he hadn’t been interested, we wouldn’t have pushed it. The classical music tribe expresses continual anguish about how hard it is to draw people into the music. Having inadvertently created a budding Beethoven lover, I have a few insights to offer. Milo got connected to the music through multiple media simultaneously, in multiple settings. He was exposed initially in the context of stories about animals and cartoon characters. That exposure happened in the context of acting and dancing, not passive sitting or being lectured to. And when he did start listening, it was via playback devices that he controls completely: YouTube Kids on the iPad, and the buttons on the book. Of all these different music experiences, the Ableton-like sample triggering is the one that has most seized Milo’s enthusiasm. Sometimes he wants to read the book and play the sounds when the text indicates. Sometimes he wants to systematically listen through each sound, singing along and acting out the instruments. Sometimes he just jams out, playing the excerpts in different orders and in different rhythms. I suspect he’d be even happier if he could get the sounds to loop. He wants to sing along, but the little phrases are half over before he can even get oriented. If the phrases looped in a musical-sounding way, I bet he would dig in much deeper. This is not Milo’s first experience triggering sample playback. Before he even turned two, we spent a lot of time playing around with an APC 40. Milo adores the lights and colors, and instantly grasped how the volume faders work. In general, though, the APC experience was too complicated for him. It was too easy to make it stop working, to lose the connection between button pushes and the music changing, and to generally get lost in the interface. (I have some of those same problems!) The orchestra book has the advantage of being vastly simpler and more predictable. There’s a page in the book that shows Beethoven with quill pen, writing the music. (Milo is continually disappointed not to see Beethoven himself in any of the performance videos.) Interestingly, Milo has started using the phrase “writing music” as a synonym for “playing music”, either from an instrument or from iTunes. He seems not to know or care about the distinction between playing back pre-recorded music and creating new music. This conflation of writing and playing music was likely helped by the time Milo has spent with the aQWERTYon, an interface developed by the NYU MusEDLab for performing music on the computer keyboard. Milo isn’t extremely interested in the musical aspect of the aQWERTYon. He calls it “ABCs” and is mostly interested in using it to type his favorite letters. He also enjoys singing the alphabet song while playing semi-randomly along. The MusEDLab’s work is motivated by the fact that computers make it enormously easier for total novices to participate actively in music. If Beethoven symphonies can be played with as toys, participated in as games, and connected to meaningful stories and activities, then it’s inevitable that kids are going to want to get involved. If I had experienced Beethoven as raw material for my own expression, I’d probably feel quite differently about him. The first song on Kanye West’s Life Of Pablo album, and my favorite so far, is the beautiful, gospel-saturated “Ultralight Beam.” See Kanye and company perform it live on SNL. The song uses only four chords, but they’re an interesting four: C minor, E-flat major, A-flat major, and G7. To find out why they sound so good together, let’s do a little music theory. “Ultralight Beam” is in the key of C minor, and three of the four chords come from the C natural minor scale, shown below. Click the image to play the scale in the aQWERTYon (requires Chrome). To make a chord, start on any scale degree, then skip two degrees clockwise, and then skip another two, and so on. To make C minor, you start on C, then jump to E-flat, and then to G. To make E-flat major, you start on E-flat, then jump to G, and then to B-flat. And to make A-flat major, you start on A-flat, then jump to C, and then to E-flat. Simple enough so far. The C natural minor scale shares its seven notes with the E-flat major scale: All we’ve really done here is rotate the circle three slots counterclockwise. All the relationships stay the same, and you can form the same chords in the same way. The two scales are so closely related that if noodle around on C natural minor long enough, it starts just sounding like E-flat major. Try it! The last of the four chords in “Ultralight Beam” is G7, and to make it, we need a note that isn’t in C natural minor (or E-flat major): the leading tone, B natural. If you take C natural minor and replace B-flat with B natural, you get a new scale: C harmonic minor. If you make a chord starting on G from C natural minor, you get G minor (G, B-flat, D). The chord sounds fine, and you could use it with the other three above without offending anyone. But if you make the same chord using C harmonic minor, you get G major (G, B, D). This is a much more dramatic and exciting sound. If you add one more chord degree, you get G7 (G, B, D, F), known as the dominant chord in C minor. In the diagram below, the G7 chord is in blue, and C minor is in green. Feel how much more intensely that B natural pulls to C than B-flat did? That’s what gives the song its drama, and what puts it unambivalently in C minor rather than E-flat major. “Ultralight Beam” has a nice chord progression, but that isn’t its most distinctive feature. The thing that jumps out most immediately is the unusual beat. Nearly all hip-hop is in 4/4 time, where each measure is subdivided into four beats, and each of those four beats is subdivided into four sixteenth notes. “Ultralight Beam” uses 12/8 time, which was prevalent in the first half of the twentieth century, but is a rarity now. Each measure still has four beats in it, but these beats are subdivided into three beats rather than four. The track states this rhythm very obliquely. The drum track is comprised almost entirely of silence. The vocals and other instruments skip lightly around the beat. Chance The Rapper’s verse in particular pulls against the meter in all kinds of complex ways. The song’s structure is unusual too, a wide departure from the standard “verse-hook-verse-hook”. The intro is six bars long, two bars of ambient voices, four bars over the chord progression. The song proper begins with just the first half of the chorus (known in hip-hop circles as the hook.) Kanye has an eight bar verse, followed by the first full chorus. Kelly Price gets the next eight bar verse. So far, so typical. But then, where you expect the next chorus, The-Dream gets his four-bar verse, followed by Chance The Rapper’s ecstatic sixteen-bar verse. Next is what feels like the last chorus, but that’s followed by Kirk Franklin’s four bar verse, and then a four-bar outtro with just the choir singing haunting single words. It’s strange, but it works. Say what you want about Kanye as a public figure, but as a musician, he is in complete control of his craft. The MusEDLab and Soundfly just launched Theory For Producers, an interactive music theory course. The centerpiece of the interactive component is a MusEDLab tool called the aQWERTYon. You can try it by clicking the image below. In this post, I’ll talk about why and how we developed the aQWERTYon. One of our core design principles is to work within our users’ real-world technological limitations. We build tools in the browser so they’ll be platform-independent and accessible anywhere there’s internet access (and where there isn’t internet access, we’ve developed the “MusEDLab in a box.”) We want to find out what musical possibilities there are in a typical computer with no additional software or hardware. That question led us to investigate ways of turning the standard QWERTY keyboard into a beginner-friendly instrument. We were inspired in part by GarageBand’s Musical Typing feature. If you don’t have a MIDI controller, Apple thoughtfully made it possible for you to use your computer keyboard to play GarageBand’s many software instruments. You get an octave and a half of piano, plus other useful controls: pitch bend, modulation, sustain, octave shifting and simple velocity control. Many DAWs offer something similar, but Apple’s system is the most sophisticated I’ve seen. Handy though it is, Musical Typing has some problems as a user interface. The biggest one is the poor fit between the piano keyboard layout and the grid of computer keys. Typing the letter A plays the note C. The rest of that row is the white keys, and the one above it is the black keys. You can play the chromatic scale by alternating A row, Q row, A row, Q row. That basic pattern is easy enough to figure out. However, you quickly get into trouble, because there’s no black key between E and F. The QWERTY keyboard gives no visual reminder of that fact, so you just have to remember it. Unfortunately, the “missing” black key happens to be the letter R, which is GarageBand’s keyboard shortcut for recording. So what inevitably happens is that you’re hunting for E-flat or F-sharp and you accidentally start recording over whatever you were doing. I’ve been using the program for years and still do this routinely. Rather than recreating the piano keyboard on the computer, we drew on a different metaphor: the accordion. We wanted to have chords and scales arranged in an easily discoverable way, like the way you can easily figure out the chord buttons on the accordion’s left hand. The QWERTY keyboard is really a staggered grid four keys tall and between ten and thirteen keys wide, plus assorted modifier and function keys. We decided to use the columns for chords and the rows for scales. For the diatonic scales and modes, the layout is simple. The bottom row gives the notes in the scale starting on 1^. The second row has the same scale shifted over to start on 3^. The third row starts the scale on 5^, and the top row starts on 1^ an octave up. If this sounds confusing when you read it, try playing it, your ears will immediately pick up the pattern. Notes in the same column form the diatonic chords, with their roman numerals conveniently matching the number keys. There are no wrong notes, so even just mashing keys at random will sound at least okay. Typing your name usually sounds pretty cool, and picking out melodies is a piece of cake. Playing diagonal columns, like Z-S-E-4, gives you chords voiced in fourths. The same layout approach works great for any seven-note scale: all of the diatonic modes, plus the modes of harmonic and melodic minor. Pentatonics work pretty much the same way as seven-note scales, except that the columns stack in fourths rather than fifths. The octatonic and diminished scales lay out easily as well. The real layout challenge lay in one strange but crucial exception: the blues scale. Unlike other scales, you can’t just stagger the blues scale pitches in thirds to get meaningful chords. The melodic and harmonic components of blues are more or less unrelated to each other. Our original idea was to put the blues scale on the bottom row of keys, and then use the others to spell out satisfying chords on top. That made it extremely awkward to play melodies, however, since the keys don’t form an intelligible pattern of intervals. Our compromise was to create two different blues modes: one with the chords, for harmony exploration, and one just repeating the blues scale in octaves for melodic purposes. Maybe a better solution exists, but we haven’t figured it out yet. When you select a different root, all the pitches in the chords and scales are automatically changed as well. Even if the aQWERTYon had no other features or interactivity, this would still make it an invaluable music theory tool. But root selection raises a bigger question: what do you do about all the real-world music that uses more than one scale or mode? Totally uniform modality is unusual, even in simple pop songs. You can access notes outside the currently selected scale by pressing the shift keys, which transposes the entire keyboard up or down a half step. But what would be really great is if we could get the scale settings to change dynamically. Wouldn’t it be great if you were listening to a jazz tune, and the scale was always set to match whatever chord was going by at that moment? You could blow over complex changes effortlessly. We’ve discussed manually placing markers in YouTube videos that tell the aQWERTYon when to change its settings, but that would be labor-intensive. We’re hoping to discover an algorithmic method for placing markers automatically. The other big design challenge we face is how to present all the different scale choices in a way that doesn’t overwhelm our core audience of non-expert users. One solution would just be to limit the scale choices. We already do that in the Soundfly course, in effect; when you land on a lesson, the embedded aQWERTYon is preset to the appropriate scale and key, and the user doesn’t even see the menus. But we’d like people to be able to explore the rich sonic diversity of the various scales without confronting them with technical Greek terms like “Lydian dominant”. Right now, the scales are categorized as Major, Minor and Other, but those terms aren’t meaningful to beginners. We’ve been discussing how we could organize the scales by mood or feeling, maybe from “brightest” to “darkest.” But how do you assign a mood to a scale? Do we just do it arbitrarily ourselves? Crowdsource mood tags? Find some objective sorting method that maps onto most listeners’ subjective associations? Some combination of the above? It’s an active area of research for us. This issue of categorizing scales by mood has relevance for the original use case we imagined for the aQWERTYon: teaching film scoring. The idea behind the integrated video window was that you would load a video clip, set a mode, and then improvise some music that fit the emotional vibe of that clip. The idea of playing along with YouTube videos of songs came later. One could teach more general open-ended composition with the aQWERTYon, and in fact our friend Matt McLean is doing exactly that. But we’re attracted to film scoring as a gateway because it’s a more narrowly defined problem. Instead of just “write some music”, the challenge is “write some music with a particular feeling to it that fits into a scene of a particular length. Would you like to help us test and improve the aQWERTYon, or to design curricula around it? Would you like to help fund our programmers and designers? Please get in touch. What rhythmic element gives this music a jazzy feeling?Fascinating Rhythm features a rhythm used often in jazz music called syncopation. Syncopation is a type of rhythm that gives stresses or accents to the weak beats instead of the strong beats.
What type of rhythm gives the music a rocking floating feeling?Up beats are the exact opposites of down beats or the pulse notes. When up beats are played in any rhythm pattern they create a sense of floating through a groove. Up Beats also can create syncopated patterns inside a rhythm groove.
What technique was frequently employed by Bartók in his music to create a highly complex and irregular rhythmic effect?17 The complexity of rhythmic patterns in these works is the result of asymmetrical meters, and he used varied metric transformations to create asymmetrical meters from symmetrical ones. It is a unique style of Bartók's composition and is widely used throughout the movements of Sonata for Two Pianos and Percussion.
What is the term used to describe a repetitive and somewhat dissonant piano part?In music, an ostinato (Italian: [ostiˈnaːto]; derived from Italian word for 'stubborn', compare English 'obstinate') is a motif or phrase that persistently repeats in the same musical voice, frequently in the same pitch.
