A chord progression raising by a fifth of an octave, repeated five times, spanning a whole octave.
Tuning is 50-equal division of the octave (note that 50 is divisible by 5).
The basis chord progression is C Eb G - Cb D G - Fb Ab Cb D - Bbb Db Fb G, which resolves to Ebb minor, at +240 cents from C. Note that 240 x 5 = 1200 cents = 1 octave.

A short Arietta with 5 variations, in 46-equal division of the octave, for organ.
The Arietta has the following tonal structure, as well as the first three variations:
F (19\46) - G/ (28\46) - A// (37\46) - C (46\46).
In general, the divisibility of the fifth (27\46) by 3 has been extensively used throughout the piece. Also, there are plenty of septimal harmonies.
