23 Laments

Theory
Listen to 23 Laments, possibly with headphones or a good sound system because of the very low pedal tones.
This is a follow-up to my previous piece Desert Winds.
This one uses a few sub-modes of the 23 EDO 7s+2m+3L mode presented on my previous esert Winds in 23EDO">article: Desert Winds.
This piece features 2 tonal centers, 313.043 cents apart, that on my Halberstadt keyboard appear on Eb and C:

Eb heptatonic sub-mode: steps 0, 1, 7, 9, 14, 15, 21, 23 (of 23 EDO)

C heptatonic sub-mode: steps 0, 7, 9, 14, 16, 20, 21, 23 (of 23 EDO)
Both sub-modes are part of the same hendecatonic mode of 23 EDO:

steps 0, 1, 3, 7, 8, 9, 10, 14, 15, 17, 21, 23
the same mode, starting on C, looks like this:

steps 0, 4, 6, 7, 9, 13, 14, 15, 16, 20, 21, 23
The song alternates between the 2 tonal centers.
The sounds are 2 of the 3 ones used for Desert Winds:

The piece consists of 5 short sections:
00:00 - 00:51 “flutish” introduction
00:52 - 01:25 vocal theme
01:26 - 01:54 chordal interlude
01:55 - 02:35 “flutish”/vocal theme
02:36 - 03:13 chordal interlude/finale
