inspired from a few years of travel, i built something that aims to bridge the gap between modern western music with historical and global tunings.

the modern western mode of 12 Tones Equal Temperament (12-TET) is the default and likely the one you are most familiar with. once comfortable with the ui, i recommend exploring other N-TET versions to see what what harmonies your intuition guides you towards!

to better help you understand these N-TET modes, there is a 2D geometric visualizer that will computes the geometric shape of your chord and match it against common chord classes (major, minor, 7ths, 9ths, etc.)

the 2D version uses a realtime 2D convex hull algo.

there is also a 3D Tower version that hacks around the 3D convex hull algo (looks accurate but not accurate)

there is also some basic synth sound design implemented as well.

please enjoy!

If anyone is unclear on how to switch to microtonal mode (okay, if you're pendantic, "xenharmonic" would be the right term), use the gear at the top-right and change the Tuning system from 12-TET to something else.

It's unusable on mobile browsers - centers the page, can't scroll left or right.

On desktop it's awesome. Very cool!

Very delightful even just to run a finger back and forth across a row on the keyboard.

Why doesn't clicking on the key spiral trigger the same visualization in the right panel that using the keyboard does?

I wonder if "shift" would be a good modifier to some of the key behavior (reverb?)

Very cool. May i suggest making the keys pizza-slice-shaped so they are slightly easier to press?

I played this piano and it reminded me of Twilight Zone (1959).

This should be in Show HN.
