Well, it could be anything. A lot of times it's a chord progression [Fig. 1], or just some groove. Around the time we were writing By the Way, I'd always be coming in with chord progressions like that-ones that have a real open, "human" sound to them. Something like that might end up being a section to a song. But sometimes those things don't go anywhere; they just go into the air. And I never remember anything, unless it's a thing I've justbeen doing. So I use a tape recorder a lot to record ideas.
