He explains his choice of visualizations for each piece... All based on a world class recording.
Here's the playlist of his favorites.

My favorite is the Canon in reverse motion, where it's laid out to show you how Bach uses mirror versions of each melody.

Or maybe it's the final Fugue on three subjects, done to show you where Bach stopped composing and how ishizaka completed the piece from elements of the entire work.

Anyway lots to explore here.
I have been wondering for a while if it's possible to show both harmonic and melodic relationships at the same time - garett's visualization shows the b7 to 1 movement as a large harmonic leap, but hides the fact that it's a small melodic movement
While listening, it occurred to me that Beethoven probably did not use a piano tuned to equal temperament. I wonder what temperament he would have used.
I don't mean to take anything away from this beautiful visualization, just something which I think would take it to the next level.
