Teaching math with the Drum Loop

I’ve undergone some evolution in my thinking about the intended audience for my thesis app. My original idea was to aim it at the general public. But the general public is maybe not quite so obsessed with breakbeats as I am. Then I started working with Alex Ruthmann, and he got me thinking about the education market. There certainly a lot of kids in the schools with iPads, so that’s an attractive idea. But hip-hop and techno are a tough sell for traditionally-minded music teachers. I realized that I’d find a much more receptive audience in math teachers. I’ve been thinking about the relationship between music and math for a long time, and it would be cool to put some of those ideas into practice.

The design I’ve been using for the Drum Loop UI poses some problems for math usage. Since early on, I’ve had it so that the centers of the cells line up with the cardinal angles. However, if you’re going to measure angles and things, the grid lines really need to be on the cardinal angles instead. Here’s the math-friendly design:

Tabla Breakbeat Science

Update: we’re working on an album. Listen to it here.

Last semester I did a project for my psychology of music class that studied the way people clap to funk/dance music. I was testing to see whether my subjects knew to clap on the backbeats or not. I didn’t give them any prompting as to how they were supposed to clap, and most people did their best to clap to the beat one way or another. The most interesting response came from my buddy Shashank, a classically trained tabla player from Bangalore. There are plenty of Indian musicians at NYU, but most of them are culturally very western — a lot of them play metal, and you’d think they were from suburban New Jersey if you didn’t know otherwise. Shashank, on the other hand, has had close to zero exposure to western music. He attempted to clap tabla patterns over the beats in my study, with strange and interesting results.

After the project was over, I thought it would be cool to hear Shashank improvise on the tabla over various classic breakbeats. We did a couple of recording sessions, and they were a lot of fun.

Software design as research

Brown, A. (2007). Software Development as Music Education Research. International Journal of Education & the Arts. Volume 8, Number 6.

My thesis is supposed to include a quantitative research component. This had been causing me some anxiety. It’s educational and creative software. What exactly could I measure? I had this vague notion of testing people’s rhythmic ability before and after using the app. But how do you quantify rhythmic ability? Even if I had a meaningful numerical representation, how could I possibly measure a big enough sample size over a long enough time to get a statistically significant result? The development of my app is going okay, but I was really stressing about the experimental component.

The Drum Loop in Xcode

Then my advisor introduced me to Andrew Brown‘s notion of software development as research, or SoDaR. As Brown puts it, “SoDaR involves computers, but is about people.” Humans are complex, our interactions with computers are complex, the way we learn is complex. The only method of inquiry that can encompass all that complexity is qualitative, anthropological inquiry, involving a substantial amount of introspection on the part of the researcher.

Hip-hop transcriptions

There’s a great Tumblr called Hip-Hop Transcriptions. It consists solely meticulous transcriptions of classic beats and rhymes by Charlie Hely. The mere fact of these transcriptions is fairly wonderful, but even better is the way that Hely lays out his charts. He uses graph paper, with each box representing a sixteenth note. This makes the complex rhythms a lot more readable than they normally would be, essentially turning standard notation into a time-unit box system. Music should always be typeset that way. Below are my favorite transcriptions.

Constructivist learning and Scratch

Brennan, K. (2013). Best of Both Worlds: Issues of Structure and Agency in Computational Creation, In and Out of School. Doctoral Dissertation, Massachusetts Institute of Technology.

I had the very good fortune to attend a fancy elementary school run on solid constructivist principles. In sixth grade I got to experience the “hard fun” of Sprite Logo. Similarly fortunate kids today are learning Logo’s great-grandchild, Scratch.

A Scratch block

Karen Brennan’s doctoral dissertation looks at the ways people teach and learn Scratch, and asks how the study of programming can help or hinder kids’ agency in their own learning. Agency, in this sense, refers to your ability to define and pursue learning goals, so you can play a part in your self-development, adaptation, and self-renewal. This is interesting to me, because every single argument Brennan makes about the teaching of programming applies equally well to the teaching of music.

Against Music Theory – some commentary

My fellow music tech student Laura Dickens had some thoughts about my recent music theory rant. This is a lightly edited version of our Facebook conversation.

Laura: Have you ever read any Susan McClary? I feel like you could probably get into that…

Me: Yes! Susan McClary is the best! She shares my belief in the joy of repetition.

Laura: Personally, I loved music theory when it became more about analysis and interpretation, and less about doing endless counterpoint exercises. All music theory is is a way of understanding music from the past, using certain rules gleaned from that music and seeing how those rules are played with by certain composers and and how those rules changed over time… although I agree with you that theory as it is taught in big institutions is very Eurocentric. It is a tool for analysis, and learning all those boring counterpoint rules aren’t so that you can then go out and write a bunch of chorales… it’s more like learning to read middle English so that you can read/analyze some Chaucer. Or learning about 17th century poetic/styles forms in order to which still influence the way poems are written today… So that’s why I think music theory is important/useful.

Against music theory

I am mercifully finished with music theory in grad school and couldn’t be happier about it. You may find this surprising. My blog is full of music theory. How could a guy who enjoys thinking about music in analytical terms as much as I do have such a wretched time in my graduate music theory classes? It wasn’t the work, I mostly breezed through that. No, it was the grinding Eurocentrism. Common-practice period classical music theory is fine and good, but as presented in a typical theory core, it’s dry, tedious, and worst of all, largely useless to a musician like me. The strict rules of eighteenth-century European art music are distantly removed from the knowledge that I need to do anything in the present-day music world (except, I guess, to become a professor of common-practice tonal theory.)

The title of this post is a reference to the Susan Sontag essay, “Against Interpretation.” She argues that by ignoring the subjective sensual pleasures of art and instead looking for rigorously logical theories of its inner workings, academics are missing the point. She calls scholarly interpretation “the intellect’s revenge upon art.” I’m with her. Music theory as practiced at NYU and elsewhere is the intellectual’s revenge on music. Sontag’s punchline is right on: “[I]n place of a hermeneutics we need an erotics of art.” Speak it, sister!

Miley vs Sinéad

I don’t know whether you’ve been following the feud between Miley Cyrus and Sinéad O’Connor, and if you haven’t, congratulations on using your free time more constructively than I use mine. But so anyway, the most infamous pop star of the moment (Miley) publically cited a well-respected elder stateswoman (Sinéad) as an influence. In response, Sinéad wrote Miley an open letter about how she should stop letting her unscrupulous management treat her like a prostitute. Miley sassed back on Twitter, Sinéad wrote an angrier open letter in response, the whole internet got involved, and around and around the whole thing continues to go.

Then this wiseacre did a mashup of Miley’s current hit, “Wrecking Ball,” with Sinéad’s signature tune, a cover of “Nothing Compares 2U” by Prince.

The thing about this is that I know it was meant as a joke, but it works extremely well musically, almost better than either of the originals. Miley wasn’t kidding when she cited Sinéad as an influence. Their sexual politics may differ, but their singing styles are uncannily similar, right down to the vocal fry. Sometimes a good mashup illuminates more than all the prose ever will.

ComposerQuest podcast with Marc Weidenbaum

Quick note to say that one of my tracks appears in a podcast by Charlie McCarron, “Social Sound Experiments with Marc Weidenbaum.” Marc is the visionary mind behind the Disquiet Junto and is a thoughtful speaker on the nature of sound art, its relationship to music, and how to be a good critic, composer and listener. The track they used is one of my recent Junto submissions. Happy listening.

Experience designers design experiences

Hassenzahl, M. (2010). Experience Design: Technology for All the Right Reasons. Morgan & Claypool.

For this week’s reading on experience design for music education, we moved up a level to think about experience design generally. A lot of design theory tends to boil down to “Design things better!” Marc Hassenzahl’s book falls into that trap a little, but he does have some useful specific ideas. His main thesis is that designers of technology aren’t just designing the technology itself. They’re designing the felt experience of using the technology (intentionally or not.) People care less about the technology itself and more about how they feel while using it.

Are You Experienced?
