When I was growing up, in L.A., I went to these schools, Fairfax High School, Bancroft Junior High School, and they had great music departments. I always played in the orchestra, the jazz band, the marching band.

When you make music, you're forming these invisible vibrations in the air into different shapes and consistencies and speeds in order to create music, and understanding how the math of that works just gives you more colors to paint with, and allows you to get to what you want quicker.

About 13-14 years ago, I went back to my alma mater, Fairfax High School, and ran into the music teacher. She invited me to come speak to the kids about the viability of a music career. When I went into the room where I used to play every day in a big orchestra, they had nothing!

Music is made up out of these building blocks. Studying how these blocks go together and what they consist of and the math of how it works - it's all the same stuff; it's just different aesthetics that we're talking about.
