Rondeau from Mozart’s Sonata for Piano #6 in Carl Lumma’s VRWT

Here it is redone using Carl Lumma’s VRWT temperament, transposed to A:
rondeau
Lovely temperament. It’s almost amazing how much better it sounds with tuning that the composer would have found attractive.

This is the 2nd movement of Mozart’s Sonata #6 K 284, Rondeau. It’s scored in the key of A major, unlike the D major in the other movements.

Doxology #3

Here is another version with some arpeggios and more interesting dynamics and timbre from Prent’s Microtonal Slide Bosendorfers.

The tuning is Just Intonation for each measure, but it changes from measure to measure, so the are many comma-sized changes from one measure to the next, where a note from one measure changes by a comma in the next.

Doxology #2

This is a realization of a hymn known as the “Old 100th”, originally written by Loys Bourgeois in the early 16th century. When I was growing up, we called it the “Doxology“, as the tune was heard most frequently as the setting for the following lyrics:

Praise God, from Whom all blessings flow;
Praise Him, all creatures here below;
Praise Him above, ye heavenly host;
Praise Father, Son, and Holy Ghost.

In my youth I sang it just about every Sunday in the Episcopal choir in Albany, NY, as a soprano.

Today’s version is a combination of the actual hymn, together with transformations where the next measure played is either the one before or the one after the current measure. It’s the Drunkard’s Walk Markov Chain, going either forward or backward through the measures.

The tuning is mostly conventional just intonation, with scales derived from the tonality diamond to the 31 limit.

Mozart Piano Sonata #6 in D – K284 Allegro – #1

Here is a version of the first movement of the Sonata I’ve been working on lately. It uses the same four scales derived from the Partch Tonality Diamond taken to the 31-limit.

  1. D1maj – take the otonality starting on 16:9 (~A#), and build a 12 note scale in the key of D major on the 10:9
  2. D6maj – take the utonality starting on 5:3 (~A), and build a 12 note scale in the key of D major on the 10:9
  3. A2maj – take the utonality starting on 5:4 (~E), and build a 12 note scale in the key of A major on the 5:3
  4. B2min – take the utonality starting on 5:3 (~A), and build a 12 note scale in the key of B minor on the 40:21

For each measure in the piece, I chose which of the four scales to deploy based on how well it plays the notes in the measure.
