ok, if you dont use chord progressions, how do you build up the musical breaks in history of japan? random chords, or bassline first then chords, or something else? Really want to learn some jazz fusion type stuff, but there isn't alot of ways how, except for listening to songs  and trying to replicate it ..
think of the melody, go to the keyboard, iron out the notes, then find good chords that make it feel the way i want it to feel. then tinker with it a lot to make it feel even better. i am very picky.
