Guessing the random element. Makes awkward music.
You play keys?

got it, I mean, it's hard to listen things excessively random, like miles davis. I'd bet on simple stuff... I'm not a keyboard player, but I have a 49-keys. It's nice for spreading harmonies (in guitar I'm limited to tight chord notes). but I never got satisfied with my chords on keyboard
Hold your horses right there.
Miles is anything but random, there is no chaos, no unstructured off beat disharmony, no my man, what appears random to the untrained ears, is nothing but chaos in its most intimate moments.
That sounds like some fancy instrument. My piano only has twelve notes. 
you're right, I expressed myself poorly indeed. sounds chaotic, but of course he knew, like hancock. just sounds crazy... it was just a figurative example. no, man my keyboard is a regular one, not fancy... it has your "twelve" notes but in four octaves, 48 + 1
