Shape of Chords

Visualize chords on the complex plane using Fourier transform at root frequency.

(Click “Learn More” to play!) There are many interesting visualization methods for pitches and chords. For example, you can put sand on a vibrating plate and patterns will form; you can shine a laser on a vibrating balloon and the reflection will draw cool shapes on a wall. These methods, however, are not mathematically unique. If you do the experiment with different equipment you will get different results. My approach, however, is free of arbitrary parameters. I want to show the one true shape of chords.
