To interact means being among others, and taking others into account in a way, to act.

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.

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.

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.

I've realized that a lot of people come to me because of what's called identity. In the sense of "he's like me" - more like identification. Identity is one of those nonsense words: it's been used so much it doesn't mean anything. As individuals, we don't want to stay the same; identity means sameness, and we don't want to be the same, we want to keep changing, we want to grow, we want to become something else. We want to evolve. So when people come to me, it's about resonance - it goes back to that word.

I notice that Indians love to tweet about each other - will be like, yeah, go India, we're awesome, Indians are awesome, here is another example of an awesome Indian. That's a dangerous false nationalism that I am not interested in. There's a huge amount of diversity within our so-called communities; within the South Asian community, there are people who would never talk to each other.

Resonance is a physical process through which similarities are highlighted.
