User interface case study: Patterning

The folks at Olympia Noise Co recently came out with a new circular drum machine for iOS called Patterning, and it’s pretty fabulous.


The app’s futuristic look jumps right out at you: flat-colored geometric shapes with zero adornment, in the spirit of Propellerhead Figure. There’s nothing on the screen that doesn’t function in some way. It’s a little dense at first glance, but a complex tool is bound to have a complex interface, and Patterning reveals itself easily through exploration.

Goodbye SoundCloud?

I love SoundCloud. I love it for being an exceptionally easy way to share my music with people all over the world. I love the community aspect, especially the Disquiet Junto. I have all of my students host their portfolios there. But like a lot of the electronic musicians who form the heart of the SoundCloud userbase, I’m running into some problems with copyright.

Recently, I needed to unwind from a stressful morning, so I fired up Ableton, put in some Super Mario Bros mp3s and James Brown breaks, and went to town. I uploaded the results to my SoundCloud page, as usual, but got one of their increasingly frequent copyright notices.

SoundCloud copyright notice

I’ve uploaded a lot of material to SoundCloud that violates copyright law in various ways, and for the most part, no one has made any objection. I’ve occasionally used some long intact samples that triggered takedown notices, but my remixes and mashups are usually transformative enough to slip through the filter. Lately, however, I’m finding that SoundCloud has dramatically stepped up its copyright enforcement. A few months ago, I could have posted my Super Mario Bros/James Brown mashup without any trouble. Not any more.

Prototyping Play With Your Music: Theory

I’m part of a research group at NYU called the Music Experience Design Lab. One of our projects is called Play With Your Music, a series of online interactive music courses. We’re currently developing the latest iteration, called Play With Your Music: Theory. Each module presents a “musical simple,” a short and memorable loop of melody or rhythm. Each simple is a window into one or more music theory concepts. Users can learn and play with the simples using a new interface called the aQWERTYon, which maps scales and chords to the regular computer keyboard.

Pedagogical remixing with Splice

My newest music student is a gentleman named Rob Precht. As is increasingly the case with people I teach privately, Rob lives many time zones away, and he and I have never met face to face. Instead, we’ve been conducting lessons via a combination of Skype and Splice. It’s the first really practical remote music teaching method I’ve used, and I can’t recommend it highly enough.

Rob came to me via this very blog. He’s a semi-retired lawyer who took some piano lessons as a kid but doesn’t have much other music training or experience. He approached me because he wanted to compose original music, and he thought (correctly) that computer-based production would be the best way to go about it. He had made a few tracks with GarageBand, but quickly switched over to Ableton Live after hearing me rave about it. We decided that the best approach would be to have him just continue to stumble through making original tracks, and I would help him refine and develop them.

Diverge, converge, diverge, converge

Soon after I became a composer, Marc Weidenbaum made me a meta-composer. Which I guess makes him a meta-meta-composer? A hyperproducer? There isn’t a word for what Marc is, aside from “awesome.” The most concise way I can think of to describe what he does: he writes reviews of music that doesn’t exist yet and then gets internet strangers to make it. Each track on this playlist is a reading of my score called “Divergence/Convergence,” and each one is quite different from the next.

Here’s Marc’s version of the narrative behind all this music. In a nutshell: I was asked to write a score for the NYU Laptop Orchestra. They performed it. I got a recording of the performance and remixed it. Marc assigned the members of the Disquiet Junto to “perform” the score solo. I got to have the strange and delightful experience of hearing all of the diverse music that resulted.

Circular rhythm visualization talk at Spotify

Today I got to talk about rhythm visualization in general and the Groove Pizza in particular at the Spotify Monthly Music Hackathon. Click the image to see my talk, I start at 1:23:47.

Circular rhythm talk at Spotify

Here are my slides:

Want me to come to your school, company, meetup or whatever, and do this talk? Or something like it? Get in touch.


The harmonica explains all of Western music

If you want to understand the cultural struggle taking place in music education right now, you could do worse than to start with the harmonica.


This unassuming little instrument was designed in central Europe in the 19th century to play the music popular in that time and place: waltzes, oom-pah music, and the like. All of this music is diatonic, meaning that it’s based around the major scale, the do-re-mi you learned in school. It’s also the music that you learn if you take a formal music theory class.

Rhythm Necklace

I have a thing for circular rhythm visualizations. So I was naturally pretty excited to learn that Meara O’Reilly and Sam Tarakajian were making an app inspired by the circular drum pattern analyses of Godfried Toussaint, who helped me understand mathematically why son clave is so awesome. The app is called Rhythm Necklace, and I got to beta test it for a few weeks before it came out. As you can see from the screencaps below, it is super futuristic.

Rhythm Necklace

The app is delightful by itself, but it really gets to be miraculous when you use it as a wireless MIDI controller for Ableton. Here’s some music I’ve made that way.

I was expecting to use this thing as a way to sequence drums. Instead, its real value turns out to be that it’s a way to perform melodies in real time. Continue reading
