Zhea Erose - Fluorescence [acoustic just intonation]

This is my first acoustic piano release in just intonation! I microtuned my baby grand piano to the Eurybian tuning + a few other unique intervals. This has been one of my favorite tunings to get lost in at the acoustic piano. Now that I have built a new studio, it's so easy for me to film musical performance videos. Expect a lot of microtonal piano and percussion in the coming days.

The tuning itself is irregular but mostly based around:
Undecimal [12] with Superfourth (Eurbyian tuning)
22:23:25:26:28:30:31:33:35:37:39:42:44
0: 1/1 0 unison
1: 23/22 76.9 undecimal m2
2: 25/22 221.3 undecimal acute M2
3: 13/11 289.2 undecimal m3
4: 14/11 417.5 undecimal M3
5: 15/11 536.9 undecimal super 4th
6: 31/22 593.7 undecimal tritone
7: 3/2 701.9 P5
8: 35/22 803.8 undecimal m6
9: 37/22 900.0 undecimal M6
10: 39/22 991.1 undecimal m7
11: 21/11 1119.4 undecimal M7
12: 2/1 1200.0 octave

Additionally the 5th octave has the A13 chord tuned to 4:5:6:7:11:13. I really love the commas created between the 28:55 and the 77:78 (used as 78:154). The comma between the 120:121 (the undecimal superfourth against the harmonic 11th) is absolutely gorgeous. The low end does have some octave stretching and the lowest D is actually tuned to 22:29 which causes D2 and D3 to be a 29:30 away from D4 and D5 while D6 is actually 120:121.

There are some other special irregularities as well such as the split note on my Eb5. The Eb5 actually plays two notes. It plays Eb5 as 44:62 and 44:56 creating a dyad on a single note.

There is one little mistake in this recording but I wanted to leave it in. I plan to do more polished recordings in the future. This is just a fun sound check.
