Adam Bell evaluates my teaching

Adam Bell is a fellow pop musician turned academic, and he hired me to teach at Montclair State University. He recently offered to observe my teaching; here’s what he found.

Teaching Observation of Ethan Hein – MUTC-101: Introduction to Music Technology

As the students began to trickle into the music technology lab and power up their iMacs, discussions immediately hatched about an upcoming assignment. A young woman turned on her speakers and played a work in progress made with the program Logic. “That’s cool!” responded one of her classmates as he listened intently. The piece commenced with a heavy guitar riff and shared sonic similarities with the “nu-metal” style of the early 2000s, comprised by the traditional trio of rock instruments: guitar, bass, and drumset. “Can we all listen to your song again? All the way through and more loudly?” asked Professor Hein. If there was a distinct moment when class had officially begun, this was it, and this was the first of many indications that the education occurring in this room under the guidance of Professor Hein is a continuing conversation that his students are engaged in and enjoying.

What if music theory made sense?

Music theory is hard. But we make it harder by holding on to naming and notational conventions that are hundreds of years old, and that were designed to describe very different music than what we’re playing now. Here are some fantasies for how note naming might be improved.

music lens

Right now, the “default setting” for western diatonic harmony is the C major scale. It’s the One True Scale, from which all else is derived by adding sharps and flats. Why do we use the C major scale for this purpose? Why not the A major scale? Wouldn’t it make more sense if harmonic ground zero for our whole harmonic system was the sequence ABCDEFG? I know there are historical reasons why the unmodified first seven letters of the alphabet denote the natural minor scale, but so what? How is a person supposed to make sense of the fact that scale degree one falls on the third letter of the alphabet?

Furthermore, I question whether the major scale really is the one we should consider to be the most basic. I’d prefer that we use mixolydian instead. The crucial pitches in mixo are close to the natural overtone series, for one thing. For another, Americans hear flat seven as being as “natural” as natural seven, if not more so. While the leading tone is common inside chords, it’s rare to hear it in a popular melody. Flat seven is ubiquitous in the music most of us listen to, and in plenty of other world cultures besides.

The saddest chord progression ever

See also the happiest chord progression ever.

The short-lived Russian composer Vasily Kalinnikov is best known (to the extent he’s known at all) for this piece of music:

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

I mentally refer to this progression as the Willie Nelson turnaround, because I first heard it in his classic recording of “I’d Have To Be Crazy”, written by Steven Fromholz. I had the pleasure of performing this tune many times back in my country music days, and it makes a great lullaby for my kids.

The version of the progression in “I’d Have To Be Crazy” uses a different harmonic rhythm, and starts on the I chord instead of vi. Nevertheless, the emotional effect is the same. Willie’s tune is in E, but again, I transposed into C for easier comparison.

Here’s a mashup of Kalinnikov and Willie:

Why do people love music so much?

We’re attracted to music for the same reason we’re attracted to fire: it’s been a critical survival tool for us for hundreds of thousands of years.

Partying in the stone age

Music cognition is one of the first high-level brain functions to emerge in infants, coming long before walking and talking. It’s also one of the last to go in people with Alzheimer’s and other forms of dementia. Music (and its twin sibling dance) are fundamental tools for soothing infants, for attracting mates, and for motivating and bonding groups ranging from kindergarten classes to infantry units. It enables us to both express our emotions and to actively modulate them, both within ourselves and among one another. Music is one of the very few known cultural universals. It’s incredibly ancient — there’s good reason to believe that it precedes language in human evolutionary history. There’s plausible speculation that it precedes bipedal walking as well. It’s no great mystery why people like it.

The real mystery is why we in modern western civilization developed the perverse idea that music is a frivolity. Steven Pinker, an otherwise very smart person who should know better, describes music as “auditory cheesecake.” Here in America, we relegate music-making to highly skilled experts, while most of us participate in it passively or not at all. We shouldn’t be surprised that depression, violence, drug abuse and suicide are epidemic in our country, even among our unprecedented levels of wealth, stability and safety. Lack of musical participation is both a cause and symptom of our unhappiness, and it demonstrates the failure of modern civilization to meet our emotional needs. In other human societies, probably in most of them throughout our deep history, music has always been a part of daily life, on a level with cooking or gossip. We would be wise to restore routine music-making to its proper place in the center of our lives.

Composing for controllerism

My first set of attempts at controllerism used samples of the Beatles and Michael Jackson. For the next round, I thought it would be good to try to create something completely from scratch. So this is my first piece of music created specifically with controllerism in mind.

The APC40 has forty trigger pads. You can use more than forty loops, but it’s a pain. I created eight loops that fit well together, and then made four additional variations of each one. That gave me a set of loops that fit tidily onto the APC40 grid. The instruments are 808 drum machine, latin percussion, wood blocks, blown tube, synth bass, bells, arpeggiated synth and an ambient pad.

Toward a statement of purpose

I’m in the process of applying for a PhD in music education, and I have to come up with a statement of purpose. Here’s my most current draft.

I dream of a world where music education serves everyone, not just potential classical virtuosos, with a radically revised curriculum that erases the distinction between “school music” and “real music.” This curriculum would be accompanied by accessible, thoughtfully designed technology for meaningful individual and group music making. Educators would incubate communities of enthusiastic music makers across skill levels and styles. My goal as a PhD candidate is to work toward making this vision a reality, using three mutually informative approaches: 1) scholarship and advocacy for curriculum change; 2) the design of new technologies and user experiences; and 3) the direct teaching of future music teachers. As a prolific and influential music blogger whose writing has been included in college syllabi internationally, I have been working toward these goals for some years already; my hope is that continued work with Alex Ruthmann, John Gilbert and the rest of NYU Steinhardt’s Music Education and Music Technology faculty will greatly increase my knowledge, credibility and reach.

My primary avenue of intended research is to design learning experiences that lead to active creative music making, even at the beginner level. Specifically, I want to devise new curriculum materials centered on the digital studio. In so doing, I hope to stem the epidemic of abandonment of formal music study. Tools like Ableton Live and Apple’s Logic are invaluable for encouraging students to produce original, culturally authentic music of their own. Creating pop tracks is an exercise with a low floor and high ceilings; novices can participate meaningfully, and experts can explore large-scale structure and novel timbral combinations. This work can and should come before theory and notation; otherwise we risk alienating the majority of would-be student musicians.

A great many teachers would naturally prefer their classes to be engaging and socially relevant rather than dry and antiquated. However, most music teachers have no idea how pop music is made. This is not due to lack of technical skill, but rather to a disconnect in musical sensibilities. The study of harmonic movement at the quarter-note level is poor preparation for music that eschews harmony completely, and the study of classical form does not give much insight into the loop structures of dance and hip-hop. Formal music education generally omits songwriting, improvisation, beatmaking, synthesis, MIDI, audio engineering, critical listening to recordings, and much else of value both to casual students and would-be pop practitioners. It is especially crucial that music teachers recognize the digital studio as a new musical medium, one that erases the distinction between composition, improvisation, performance, recording and mixing. Digital audio editing makes it possible for young musicians to approach the artifacts of their culture as producers rather than consumers, and enables even complete beginners to engage with music at the intuitively approachable level of riffs, phrases, chord cycles, and drum patterns. Approaching music this way does not just give entry into pop; it also opens new inroads into the study of jazz and classical. One of my main goals as a scholar is to devise music education curriculum materials that will help teachers adapt to this new paradigm.

Montclair State student works with Logic

The design of music learning technology is as important as the design of curricula. Indeed, the education of most pop musicians takes place outside of a classroom, in large part through direct trial and error. In this context, the presets, default sounds and user interface affordances in music production software and hardware are de facto music teachers with enormous cultural reach and impact. As Dr. Adam Bell (NYU Steinhardt PhD 2013) memorably put it, “purchasers of computers are purchasers of an education.” I would like to find ways to make that educational experience a better one. My intimate expertise both with formal theory and informal pop practice makes me ideally suited to design music education technology. My Masters thesis was a prototype introductory-level rhythm learning app that uses an innovative radial visualization scheme combined with creative exercises drawn from genuine dance, pop and hip-hop repertoire. I have since been asked by engineers at iZotope and Ableton for design insights, and my blog posts on interface and experience design have a substantial and growing global following.

My thinking on the role of technology in music education has been shaped profoundly by the MusEDLab, with whom it has been my privilege to work as a researcher for the past year. The Groove Pizza, an outgrowth of my Master’s thesis, is an emblematic MusEDLab project: a circular drum machine that visualizes rhythm patterns in the arrangement of plastic mushrooms, pepperoni and sausages. Beyond the novelty of the form factor, we believe that there is deep value in circular rhythm visualization as an intuitive representation of the loops comprising all pop and dance music. Radial rhythm visualizations also have rich value outside the music classroom; for example, they can be used to teach mathematical subjects including ratios and proportional relationships, angles, polar coordinates, rotational and reflectional symmetry, and modular arithmetic. I expect that my doctoral studies will dovetail neatly with the MusEDLab’s work, and that the two will mutually inform each other. I look forward to sharing the findings of our research with advocates for change in music curricula at the university as well as the primary and secondary school levels.

My own teaching practice has been and will continue to be a proving ground for new approaches. As an adjunct at NYU and Montclair State University, I am introducing future music educators to the possibilities of technology in the classroom, as both a toolkit for teaching music fundamentals and for fostering creative expression even at beginner levels. This work has already informed my thinking about the potential for experience design to make musical practice more accessible. I eagerly look forward to using my doctoral studies to engage in evidence-based design of new music learning experiences, to advocate for the adoption of those experiences, and to help teachers bring culturally authentic music into the classroom. In so doing, I hope to widen access to the essential social vitamin of active musical practice, and to guide students toward the discovery of their own musical truths. Thank you for your consideration.

 

How to write a pop song

My students are currently hard at work writing pop songs, many of them for the first time. For their benefit, and for yours, I thought I’d write out a beginner’s guide to contemporary songwriting. First, some points of clarification:

  1. This post only talks about the instrumental portion of the song, known as the track. I don’t deal with vocal parts or lyric writing here.
  2. This is not a guide to writing a great pop song. It’s a guide to writing an adequate one. Your sense of what makes a song good will probably differ from mine, whereas most of us can agree on what makes a song adequate. To make a good song, you’ll probably need to pump out a bunch of bad ones first to get the hang of the process.
  3. This is not a guide to writing a hit pop song. I have no idea how to do that. If you’re aiming for the charts, I refer you to the wise words of the KLF.
  4. You’ll notice that I seem to be talking a lot here about production, and that I never mention actual writing. This is because in 2014, songwriting and production are the same creative act. There is no such thing as a “demo” anymore. The world expects your song to sound finished. Also, most of the creativity in contemporary pop styles lies in rhythm, timbre and arrangement. Complex chord progressions and intricate melodies are neither necessary nor even desirable. It’s all in the beats and grooves.

To make a track, you’ll need a digital audio workstation (DAW) and a loop library. I’ll be using GarageBand, but you can use the same methods in Ableton Live, Logic, Reason, Pro Tools, etc. I produced this track for illustration purposes, and will be referring to it throughout the post:

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.

All student work should go on the web

Well, it’s official. All of my students are now henceforth required to post all music assignments on SoundCloud. It solves so many problems! No fumbling with thumb drives, no sharing of huge files, no annoyances with incompatible DAWs. No need to mess with audio-hostile Learning Management Systems. Everyone gets to listen to everyone else’s music. And best of all, the kids get into the habit of exposing their creative work to the blunt indifference of the public at large. Students can comment on and fave each others’ tracks, and so can randos on the web. It really takes the “academic” out of academic work.

A book you should read

I’m currently reading On Immunity by Eula Biss, which is so good you can’t believe it. Recommended if you’re interested in vaccination, health generally, being a parent, gender, race, class, the history of medicine, Greek mythology, vampires, or if you just need an example of how to parse out a difficult subject in a warm and elegant manner.

On Immunity

Also, if you have money and want to make a well targeted public health intervention, I recommend buying a bunch of copies and handing them out in front of the Park Slope Food Coop and the equivalent locations in Berkeley, Ann Arbor, Laurel Canyon, Portland, and wherever else well-educated professionals aren’t getting their kids vaccinated.
