hm this is a super ignorant and embarrassing post for op. Should have just said you don’t understand jazz patterns. While there is a lot of improvisation and movement, it is all formed around specific jazz chord progressions and the “chaotic” parts you refer to usually resolves with chord changes. Would highly recommend listening to John Coltrane, Errol Garner, etc. I think those in particular play their instruments very well and extremely soulfully.
