Harmony is the third element of music, after melody and rhythm, and also the one which requires the most study to actually master. People can be very instinctive and extremely gifted melodically and rhythmically, and harmony can still be difficult.

Being a mathematical genius doesn't do you any favors as far as having something to say in music. You see every style as equal, and you want complicated music to devour.

To me, a performance is a military operation; it requires so much planning, and then ripping up the plan the minute you get there because you have no idea what the audience is feeling. I'm very much an entertainer, and sensitive to the audience's perception of me. I often have to do unexpected things, even for myself.

A lot of comedians today have misunderstood the concept of a subversive comedian. If you really want to be subversive, you have to please and offend in equal amounts.

If you're going to point out the ridiculousness of a rule, it's naïve to think that you can break it. It's the same way that rappers have embraced capitalism. Some people say they liked it better when rap was a literal protest form in the '90s. But I think it's more a form of protest today, because it's telling the story of what happens once something forbidden is within reach. I think rap is more political today when it speaks about luxury watches than it does about fighting the power.

Without the piano, I would never have attempted to rap, because I'm a poor rapper. I'm enthusiastic, but it takes me a long time to write eight bars of rap. I would battle any pianist, and yet I would forfeit happily before even getting into a rap battle with anyone.

It will lead many musicians out of the cul-de-sac they currently face. And those that do not understand will be cursed to make disposable music on laptops forever.
