Bach for Christmas

Al Vachris sent me a link to this visualisation of the opening Prelude from Bach’s 1st Suite for Solo Cello:

“Baroque.me (2011) by Alexander Chen. Video capture. baroque.me visualizes the first Prelude from Bach’s Cello Suites. Using the math behind string length and pitch, it came from a simple idea: what if all the notes were drawn as strings? Instead of a stream of classical notation on a page, this interactive project highlights the music’s underlying structure and subtle shifts.”

This visualisation is entirely computer generated, and has none of the subtleties of a human performance, nonetheless the listener generates their own dynamics to some extent.  Compare with a real performance, an early video recording by Pablo Casals (made in 1954, when Casals was 77):
