How to tell funk from disco

Here’s a short excerpt from my blues tonality paper that I thought would stand alone well on its own.

How do we decide that a song is rock, or folk, or country, or country-rock, or folk-rock? Nearly all American popular and vernacular is informed by blues. We can use this fact to help delineate overlapping and vaguely defined genre boundaries. Just as we can explain genre in terms of characteristic rhythms and timbres, so too can we explain it in terms of the amount of blues harmony present. Good pop and jazz practitioners already do this implicitly. A guitarist or singer needs a sense of how much blues tonality to use in order to sound more characteristically ‘jazzy’ or ‘country’ or ‘rock.’

Let’s use the example of funk. Aficionados like me know when music is funky. But how do we know? The most obvious characteristic to point to is the beat. But you can also hear funk rhythms in disco, hip-hop, R&B, rock, and even country — Dolly Parton’s “Jolene” is super funky. We can distinguish funk as a genre more specifically using its harmonic content. Funk is the most heavily blues-based genre aside from blues itself. While rock and country combine blues harmony with diatonicism, funk adds in jazz harmony instead.

The saddest chord progression ever

My fellow NYU adjunct Rebecca Feynberg recently hipped me to Vasily Kalinnikov.

If you listen to this piece at 6:16, there’s a particularly lovely and tragic chord progression. It’s in the key of E♭, but I transposed it into C for ease of understanding:

||: Am | D7 | Fm | C :||

I mentally refer to this progression as the Willie Nelson turnaround, because he uses it extensively in his classic tune “I’d Have To Be Crazy.” I had the pleasure of performing this many times back in my country music days, and it makes a great lullaby for Milo.

Willie’s version uses a different harmonic rhythm, and starts on the I chord instead of vi, but the emotional effect is the same. Willie’s tune is in E, but again, I transposed into C for easier comparison.

|| C | % | % | % | D7 | Fm | C | % ||

At the top of the tune and in various other spots, he also uses this variant:

|| C | % | G7 | % | D7 | Fm | C | % ||

Ableton Session View and instrument design

We usually think of “recorded” and “live” as two distinct and opposed forms of music. But technology has been steadily eroding the distinction between the two. Controllerism is a performance method using specialized control surfaces to trigger sample playback and manipulate effects parameters with the full fluidity and expressiveness of a conventional instrument. Such performance can take place on stage or in the studio.

Controllerism is attractive to me because I came to music through improvisation: blues, jazz, jam bands. I spent years improvising electronic music with Babsy Singer, though she did the beats and loops, not me. My life as a producer, meanwhile, has involved very little improvisation. Making music with the computer has been more like carefully writing scores. Improvisation and composition are really the same thing, but the timescales are different. Improvisation has an immediacy that composing on paper doesn’t. The computer shortens the loop from thought to music, but there’s still a lot of obligatory clicking around.

It’s certainly possible to improvise on the computer with MIDI controllers, either the usual keyboard variety or the wackier and more exotic ones. Improvising with MIDI and then cleaning up the results more meticulously is pretty satisfying, though my lack of piano skills make it almost as slow and tedious an input system as the mouse. Jamming on iPhone and iPad apps like Animoog or GarageBand is better. What they lack in screen real estate, they make up for with form factor. Making music on the computer comes to feel like office work after a while. But you can use the phone or the tablet while lying in bed or on the ground, or while pacing around, or basically anywhere. Multitouch also restores some of the immediacy of playing instruments.

There’s also the option of recording a lot of vocal or instrumental improvisation, and then sorting out all the audio afterwards. This is the most satisfying strategy for infusing electronic music with improvisation that I’ve found so far. You get all the free-flowing body-centered immediacy of live jamming, with no pressure whatsoever to be flawless. However, then you have to do the editing. It’s easier now than it was five or ten years ago, but it’s still labor-intensive. It can take an hour of work to shape a few minutes of improv into musical shape.

All of this time, I’ve had severe DJ envy, since their gear is designed for immediacy and improvisation. It’s a lame DJ indeed who meticulously stitches together a set ahead-of-time in an audio editor. However, DJ tools operate at the level of entire songs. It’s not easy to use Serato to write a new track. I’ve been wanting a tool that gives me the same sense of play, but at the scale of individual samples rather than entire songs.

Enter the APC40. The form factor resembles an MPC, and you can use it that way, to trigger one-shot samples like drum hits or chord stabs. But the intended use case is for Ableton session view, starting and stopping the playback of loops. By default, loop playback is quantized to the bar, so whenever you hit a pad, the loop begins playing cleanly on the next downbeat. (You can set the quantization interval to be as wide or narrow as you want, or disable it completely.) Playing your loops live makes happy accidents more likely. Of course, unhappy accidents are more likely too. But those are easy to fix in Arrange view. When I discovered that NYU has a little-used APC, I signed it out and started teaching myself controllerism. Here’s a picture of it.

It seems complex, and it is. The Starship Enterprise quality appeals to my tech nerd side. Creating an Ableton session for APC playing is like inventing a new musical instrument, every time. After you design your instrument, then you have to learn how to play it. On the other hand, if you design your instrument right, the actual playing of it can be fun and easy. When I set up the APC with some Michael Jackson samples and let Milo try it, he figured out the concept immediately.

Electronic music tasting menu

Right now I’m teaching music technology to a lot of classical musicians. I came up outside the classical pipeline, and am always surprised to be reminded how insulated these folks are from the rest of the culture. I was asked today for some electronic music recommendations by a guy who basically never listens to any of it, and I expect I’ll be asked that many more times in this job. So I put together this playlist. It’s not a complete, thorough, or representative sampling of anything; it mostly reflects my own tastes. In more or less chronological order:

Delia Derbyshire

This lady did cooler stuff with tape recorders than most of us are doing with computers. See her in action. Here’s a proto-techno beat she made in 1971.

Repetition defines music

Musical repetition has become a repeating theme of this blog. Seems appropriate, right? This post looks at a wonderful book by Elizabeth Hellmuth Margulis, called On Repeat: How Music Plays The Mind, investigating the reasons why we love repetition in music. You can also read long excerpts at Aeon Magazine.

Here’s the nub of Margulis’ argument:

The simple act of repetition can serve as a quasi-magical agent of musicalisation. Instead of asking: ‘What is music?’ we might have an easier time asking: ‘What do we hear as music?’ And a remarkably large part of the answer appears to be: ‘I know it when I hear it again.’

Remixing “Here Comes The Sun” in 5.1 Surround

For my final project in Advanced Audio Production at NYU, I created a 5.1 surround remix of the Beatles’ “Here Comes The Sun.” You can download it here. If you don’t have surround playback, you can listen to the stereo version:

I was motivated to create a surround remix of a Beatles song by hearing the Beatles Love album in class.

I chose “Here Comes The Sun” because I have the multitracks, and because I heard potential to find new musical ideas within it. Remixing an existing recording is always an enjoyable undertaking, but the process takes on new levels of challenge and reward when the source material is so well-known and widely revered. Much as I enjoy Beatles Love, I feel that it didn’t take enough liberties with the original tracks. I wanted to depart further from the original mix and structure of “Here Comes The Sun.”

Did Yoko Ono break up the Beatles?


Paul McCartney joined John Lennon’s skiffle band in 1957, when they were fifteen and sixteen, respectively. George Harrison joined the following year, when he was fourteen. (Ringo didn’t join the band until 1962.) Who were your friends when you were fourteen, fifteen, sixteen? Imagine yourself intensely and inseparably joined with these same people professionally, socially and creatively, thirteen years later. When I was in my late twenties, I certainly wouldn’t wanted to have been trapped in a series of windowless rooms with my high school friends under enormous pressure to be brilliant. It would have been a miracle for the Beatles to keep a good working relationship any longer than they did under the best of circumstances. And the Beatles’ circumstances were not, emotionally speaking, ideal.

Visualizing song structures

How do you write out a pop, rock or dance song? There’s no single standard method. Some musicians use standard western notation. Some do everything by ear. Many of us use methods that fall somewhere in between. One such compromise system in widespread use is the lead sheet:

Other systems for song documentation include chord charts and the Nashville numbering system. But plenty of musicians are unfamiliar with these systems, and may not have any method for writing down songs at all. This leads to a lot of confusion during rehearsals and recording sessions. Any given section of a rock or pop song is likely to be simple, a few chords in a particular pattern, but the difficulty comes in figuring out and remembering the bigger structure: whether the guitar solo comes after the second verse or the chorus, how many bars long the bridge is, what beat the ending falls on.

Originality in Digital Music

This post is longer and more formal than usual because it was my term paper for a class in the NYU Music Technology Program.

Questions of authorship, ownership and originality surround all forms of music (and, indeed, all creative undertakings.) Nowhere are these questions more acute or more challenging than in digital music, where it is effortless and commonplace to exactly reproduce sonic elements generated by others. Sometimes this copying is relatively uncontroversial, as when a producer uses royalty-free factory sounds from Reason or Ableton Live. Sometimes the copying is legally permissible but artistically dubious, as when one downloads a public-domain Bach or Scott Joplin MIDI file and copies and pastes sections from them into a new composition. Sometimes one may have creative approval but no legal sanction; within the hip-hop community, creative repurposing of copyrighted commercial recordings is a cornerstone of the art form, and the best crate-diggers are revered figures.

Even in purely noncommercial settings untouched by copyright law, issues of authorship and originality continue to vex us. Some electronic musicians feel the need to generate all of their sounds from scratch, out of a sense that using samples is cheating or lazy. Others freely use samples, presets and factory sounds for reasons of expediency, but feel guilt and a weakened sense of authorship. Some electronic musicians view it as a necessity to create their tools from scratch, be they hardware or software. Others feel comfortable using off-the-shelf products but try to avoid common riffs, rhythmic patterns, chord progressions and timbres. Still others gleefully and willfully appropriate and put their “theft” of familiar recordings front and center.

Is a mashup of two pre-existing recordings original? Is a new song based on a sample of an old one original? What about a new song using factory sounds from Reason or Ableton Live? Is a DJ set consisting entirely of other people’s recordings original? Can a bright-line standard for originality or authenticity even exist in the digital realm?

I intend to parse out our varied and conflicting notions of originality, ownership and authorship as they pertain to electronic music. I will examine perspectives from musicians and fans, jurists and journalists, copyright holders and copyright violators. In so doing, I will advance the thesis that complete originality is neither possible nor desirable, in digital music or elsewhere, and that the spread of digital copying and manipulation has done us a service by bringing the issue into stark relief.
