I'm what they call a 'non-black person of color': NBPOC. It's easy and seductive and common to mobilize around these identity issues, but often that's done at the expense of considering structural anti-blackness. That puts everything in a slightly different light for me, especially because of where I am and why - where I am in the world of the arts, where I live, in Harlem - and the music that I've been able to make, whom I've been able to make it with, who has nurtured me. It's not just about solidarity. It's actually about debt.

I want to make sure that I represent a variety of backgrounds and that represents the reality out here in the world.

The phrase I use is 'easy camaraderie.' Non-western immigrants of color and their progeny like me - my parents came here fifty years ago and I was born and raised in Rochester - whether it's Teju Cole, or Rudresh Mahanthappa, or Himanshu Suri, or Miya Masaoka, or Barack Obama, we all have that in common. And that's different from being descended from enslaved African captives. I am very conscious of that difference, and conscious of how easy it is to forget about it. I find myself always coming up against that.

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.

Music is made of what we do when we move, and we can only move in certain ways, in certain ranges of tempo because of the inherent constraints that our bodies offer, or you can call them 'affordances' - that's another word for me. It's a little more positive; doesn't make it seem like a limitation, but rather, a set of opportunities. You can say that that's part of music making, but there's also the imagination. The power of the imagination is kind of trumping - sorry to have to use that word.

Music making features real-time creation, real-time decisions and actions. It's basically improvisation, which is the stuff of everyday life. In the realm of discourse about music, improvisation is marginal, but in the realm of doing it, it's omnipresent. Strange distinction here: we're improvising all the time, but when we tend to talk about music, we tend to talk about objects that are fixed, like recordings, scores, pieces.

I think what music can offer is the feeling of forward motion, also the feeling of accumulation of information, of sensations, of feelings, like we're going somewhere. When I say 'feel like,' I don't mean to suggest that it's not real, but that it's the work of the imagination, which is what narrative is.
