Ach wie flüchtig, ach wie nichtig BWV 26 #3

Here is a finished version with slides alternating with the eighth note scalar moves (major and minor 2nds only).

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.

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.
