[OC] Music composition, Ravel: Gaspard de la nuit, No. 1 “Ondine” mapped in color

I’ve been experimenting with a way to turn the harmonic character of a song into a single image. Folks have been visualizing music for centuries, but this is one approach I’ve been working on, using software I built to map pitches to colors by aligning the circle of fifths with the color wheel.

Each pitch gets a fixed hue. Note length determines how long a color bar runs, and chords stack those bars vertically. Because the mapping follows the circle of fifths, harmonies that are closely related appear as neighboring colors, so consonant passages read as a unified palette. When the harmony moves into more distant relationships, the colors spread farther around the wheel, matching the rise in harmonic tension. I generally avoid spacing between bars so it reads as one continuous field, giving more of a macro view than a measure-by-measure read.

I’m considering turning the series into art prints or starting to make these as custom works and I'm curious what folks think.
