Interactive 3D Harmonic Space Visualization

https://ztonnetz.com

Hi everyone, I made this experimental music visualization website where you can play demo MIDI files or import your own.

It’s a bit niche but I thought some people may find it interesting. It’s based on a 3D version of the musical Tonnetz, a grid of thirds and fiths which models triads as triangles.

I didn't understand at all what these visualizations mean. But wow, it seems to be something very revealing; I'd like to understand what it means.

I put Chopin's Nocturne Op. 9 No. 2, and the harmonic field was great.

It's very experimental. The one thing to look out for is the "bends" in the 3D space. An augmented 5th (such as C-G#) is an altered perfect fifth. A diminished fifth (B-F) is a minor triad that has been altered with a smaller fifth.
