Music and writing do fold together in the sense that you have to have a certain level of skill in order to execute your ideas and you need a medium. The idea of improvisation is one that many writers fall into, and I improvise a great deal when I'm writing, but there's a structural framework that I'm working around, and that takes more time than the actual writing. Once the characters get to yapping and talking, they'll move from one room to the next, and I just have to make sure that the house is built. That's really hard, that's the kind of thing that sits with you all day long.
