This is one of Bach’s Chorales, scored for SATB, performed on Prent’s Microtonal Slide Bosendorfer. The title means “Ah, how fleeting, ah how insignificant” in English. I broke the piece up into its 39 quarter note length segments, and either play it straight, or backwards and forwards using the Markov Chain Drunkard’s Walk. There are a lot of eighth notes, and in this version they are all discrete notes. I intend to make them have the option of slides in the next version.
The tuning is derived from the 31-limit tonality diamond, with each quarter note segment assigned a scale that makes that chord sound best, including with 6/5 and 5/4 thirds, 3/2 fifths, and 7/4 flatted sevenths. That leaves some harsh notes, as the commas between chords are pronounced. I may go back and make them slide from one chord to another so that they are masked. That’s for another version also.
