I have been given a wonderful chance in my life: to be able to create music easily under any circumstances. Music is a constant flow in my head. Whatever I'm doing: Practicing, resting, driving a car, doing sport, watching a movie, music is always there.
It doesn't mean this music is always good, it may be sometimes without interest, but it bursts out in my ears anyway.
When I am home, I simply record the idea if possible, or write it down if not. When I am outside, I always carry a little music notebook.
Then I sometimes take the time to listen back to some of these ideas and decide for what purpose it would be the most appropriate, one of my band, a solo work, an improvisation frame or a New Music piece.
Sometimes, I find the idea not so interesting and it ends up in the trash bin.
But sometimes, I find it good but not fitting to any of the projects I mention above. Then it becomes an archived sketch, something that I can't use right now, but which I keep, waiting for an opportunity to use it.
