This amazing video visualizes the first Prelude from Bach’s Cello Suites. Each note is represented as a string and the string length denotes pitch. What really impresses me that the dots which seem to just hang about making circles are actually moving at a speed that results in them ‘plucking’ the strings. Part of the math involved is that the creator, Alexander Chen, uses Pythagorean tuning to estimate the length of the strings. But ignore my convoluted efort to explain what is happening and just check this out:
