captive audience

animation + music theory = fantastic idea!

in classical-speak, coltrane's trick might be called a 'modulation to the mediant' but on acid. or i guess opium.
beethoven was the trendsetter, in his piano sonatas. brahms and schubert bit that ish hard.

there's a certain pi(the movie)-esque symmetrical grace to coltrane's version tho that maybe, at that time, only someone like bach could have really appreciated.

here is a pretty giant steps animation (that doesn't inform that much as far as i can tell)
