Thats insanely beautiful. Thank you for sharing!!

I have a mild case of synesthesia and this is one of the closest things I have seen/heard (:) ) that comes close-ish to capturing how I see/feel when I experience great music.

Of course, I was not surprised to see the creator of the video list a similar motivation in his caption for the upload.

Don't understand the downvote. The first video may seem arbitrary to people not familiar with jazz theory but it's a really good representation of the structure of one of clotrane's most emblematic song. Thanks for sharing !

The downvote wasn't me but I'll agree that this doesn't seem much more related to the music than any visual synced to the tempo. Coltrane's drawing captures a system that could be used by other musicians to create new musical ideas or theories. They're very different things so the video seems off-topic to me.

I still haven't figured out how to play over Giant Steps changes, although shredding through augmented scales has about a 50% success rate.

The fun thing about Giant Steps is that if you hold any note for long enough, eventually it will resolve correctly.
