Today, J. S. Bach would have been 333 years old. In honor of the day, this organ piece.
A “Toccata” in Bach’s day was a virtuosic type of prelude with somewhat improvisational character—the word comes from the Italian verb ‘toccare’, which means both ‘to touch’ and ‘to play [a musical instrument]’. Bach actually wrote two “Toccata and Fugue” pairs in D minor: the extremely familiar BWV 565 with its stark musical contrasts, and the misnamed “Dorian Toccata and Fugue” BWV 538 with its driving perpetual motion in the toccata. It is actually in D minor rather than D dorian, but the (in the modern era) unusual notation without a key signature led to the erroneous nickname.
Below is a scrolling-score video — the audio is a performance by the great French organist Michel Chapuis, in standard pitch. Enjoy!
