“You play with some ideas as a composer, you want them to show you something. It’s a technical experimentation with different forms, but then something happens, and the music starts to play with me. And then I play with it again. It’s like a love relationship, or a form of sex – in the best sense.”

German composer Wolfgang Rihm, speaking about his work in an interview with The Guardian.
I imagine that that music composition, more so than writing or visual art, lends itself to conversational creativity as described by Rihm - by its very nature it’s a labile media and responds to the emotions of the player/composer as they interpret/reinterpret the score.
