Lately I've been trying to push outside my comfort zone, and am writing poly tonal music that is similar in style to Bartok, or perhaps Stravinsky. I have been doing this mostly by ear, and to be honest, I could not explain how most of the harmonies function within the piece. So, the question is how common is this? Do fellow composers here write the same way? My current teacher thinks what I'm writing fits, and is consistent enough in each piece that it doesn't sound out of place, but I can't help but feel a little bit unsettled about it right now.
BTW stay tuned for an upload of one of my pieces (written in this style) to the music dissection page.
