what is a-tonal jazz and 12-tonal jazz and how is it different from traditional jazz?
well, as far as i know, atonal music is any music where key signatures and time signatures don't exist. any note is alright to play whenever you feel like it. i'm sure there are more restrictions, but thats the jist of it i think
There is no tonal center, so the piece is in no particular key that the piece is in. Can be very chromatic
