When I give a concert, I know they're not going to hear everything; there might be a lot going on. My individual perceptual and cognitive path through the music is just that: one path through music. My experience will be probably at some level different from other people's, and that multiplicity of experience has to be supported by the music. I might just focus on the cowbell the whole time - maybe I have a fever for more cowbell!

I teach a graduate seminar called "Theorizing Improvisation" that is pretty interdisciplinary, but really makes students deal with black studies seriously. A lot of authors of color, a lot of women of color - those become central to the intellectual trajectory. It considers music, but it also considers areas of thought that might seem unrelated to music. That's partly because we're expanding the notion of what music is beyond objects, beyond scores, beyond things.

With electronic music it's often a little more hidden - the relationship between gesture and sound - which makes it confounding for audiences. But the ingredients of electronic music are the same ingredients of nonelectronic music.

I find myself skeptical of music that forces you to have a certain experience, emotional reaction, or specific constructive arc of experience. But performers should still take care of that, to a certain extent - how does it add up? What you want from performance, because we're all in a room together, is that somehow we've gotten somewhere at the end, together. You could call that a sense of narrative, but it's not so obvious how that happens. One way it happens is by everyone caring about it happening.

It is one thing to be a virtuoso, but a different thing to play with compassion.

What I've learned from my gurus is that when you hear music, you hear a person, or you hear people, and you hear everything about them in those moments. They reveal themselves in ways that cannot be revealed any other way, and it contains historical truths because of that. To me, that is the most important thing. It shouldn't be a footnote, or the last chapter. It should be the complete thesis about a book on listening.

The thing about physicists is that they tend to think that everything is physics. I don't. That's not what music is to me. You can explain aspects of it in physical terms, including the physics of anatomy: how our bodies move, the torsional moment of inertia, the way you move your body to a beat, the inherent periodicities of the heartbeat, the gait. That's physics, too, I guess - maybe they'd call it biophysics.
