Perhaps you have some ideas of your own you’d like to share.
Or perhaps you’d like to merely copy and paste a few music writers who wanted to publish a vaguely plausible “story” to meet their deadlines.
A lot of stretching going on there.
Rap is just as much “born out of jazz” as Katy Perry is “born out of classical.”
We can flex, balance (much love, Mr. Van Vliet) and stretch some more until the cows come home.
The degree to which the vast majority of hip hop is based on extremely complex compositions (the majority of mainstream rap barely qualifies as being a ‘composition’ at all, as it is often a series of samples and loops of previously composed/recorded material) be it,
a) complexity of harmonic relationships,
b) complexity of rhythm/time signature, and,
c) compositional structure,
is infinitesimal compared to all of the above in jazz.
The degree to which the music is defined by virtuosic improvisational instrumental acumen, whether in a recorded or live performance capacity, is equally infinitesimal compared to jazz.
