Visualization of Music

[youtube] This is a visualization of the composer Baldassare Galuppi's Toccata in D Minor. A toccata is a very special type of piece, a virtuoso piece typically for a keyboard or plucked string instrument, but also sometimes for full orchestras, featuring fast-moving, lightly fingered or otherwise virtuosic passages or sections, with or without imitative or fugal interludes, generally emphasizing the dexterity of the performer's fingers. It's a beautiful breakdown or analysis of this fast moving rhythm.
