I think it is rather easy to become like a train as a composer, following the path or tracks one has created for oneself (or that have been laid down for one), more or less oblivious to what other composers are doing. Indeed, at some level that is essential; for in no other way would one be able to become a composer, an original composer, to forge one's own path as a composer. And yet, one can become too fixed in one's tracks, too much on autopilot as regards one's formula of composition. How then does one introduce novelty? (Or how does one develop, evolve, or progress as a composer?) I think the challenge would be to introduce novelty but not "novelty for the sake of novelty". How does one do that? Indeed, can one even do it deliberately? Perhaps the challenge is to find the right balance between novelty and a recognizable style. Or to unconsciously pursue novelty, to be upon a course of unconscious evolution along the path forged by one's compositional style. What are your thought and insights about this?
