I was just having this conversation last night: what makes something 'jazz' (or classical or rock, etc).
MANY people say jazz = swing, and there is NO swing in my music. Some say that having improvisation = jazz. There is improvisation in my music, but more through-composed music. And rock, blues, metal, etc. have improvisation, too.
Is it the vocabulary in the improvisation? I've never learned or transcribed a jazz solo in my life - my vocab is purely what I've picked up from listening to all kinds of music.
Is it the instrumentation? Does having saxophone and double bass make it jazz??
I'd say, beyond any doubt, that my music more closely resembles rock and classical music than it does jazz (while there are certainly elements of jazz in it).
