Shades and Tones

Rhythm, vibration, frequency, tone, timbre, shade…

If we had pianos that could play 40 octaves above the ones in our concert halls, where we'd tune to A483785116221440 instead of A440, and that would produce electromagnetic-waves rather than sound-waves, we could play colors. Imagine a MIDI controller that signals a group of LEDs - it's totally workable, but I don't have the programming skills. Anybody want to help build an instrument?

Also - take note of the colors present in different chords.

e.g.,  a major chord, G B D  = RedGreenBlue …
This example, I think, only works for lifeforms with at least three kinds of photoreceptors (trichromats), like us humans. Dogs, for example, are dichromats; sorry dogs.

In music, an octave consists of a low note and a high note (and those encompassed), the higher note being exactly twice the frequency of the lower.

The human ear can detect roughly from 20Hz to 20KHz: about 10 octaves - this varies a bit from person to person, and the upper range diminishes with age.

The human eye detects light roughly in the 384 - 769THz range.

384 * 2 = 768

Isn't it interesting that the human eye can detect approximately one octave of light?
That's funny…
