Tau (τ) is defined as the ratio of the circle circumference to the circle radius therefore making it equal to 2π. I personally think τ makes more sense than π since the circle radius is more fundamental of a property than its diameter.
In this video, I mapped the fraction part of the first 1000 Tau digits to musical notes and to colors.
The musical mapping uses the chromatic scale while color mapping uses a slightly modified version of matplotlib gist_rainbow color map.
