The bass line is the anchor for me. I started with the bass, and either doubled that and then added the harmonies, or sometimes added my own harmonies that I've always wanted to sing on the song. And then it just went on from there - singing violin parts and trumpet parts and just trying to emulate the sounds of the instruments.
I'm not a person who writes really abstract things with oblique references. I look at abstraction like I look at condiments. Give me some Tabasco sauce, some ketchup, some mayonnaise. I love all of that. Put it on a trumpet. I've just got to have the ketchup and Tabasco sauce. That's my attitude about musical philosophy.
