Name: Superpyth Pantonal Music - 22 EDO by pianofreak96
Duration: 9 min 13 s
Description: Two Piano Pieces written in the Superpyth[12] scale of 22 Equal Temperament. This is pantonal so that means it's not in a particular 7 note key but one giant 12 tone tonality.

For some reason your piano synth music always sounds really forgiving to mistuning. And expressive.

Superpyth temperament can be thought of as a mirror opposite of meantone temperament. In meantone temperament four fifths reduced an octave is equated to the 5-limit just major third 5/4, where 4 pure fifths of 3/2 reduced an octave give 81/64, larger than 5/4 by the meantone comma, 81/80. In quarter comma meantone each fifth is flattened by a quarter of this comma so that four of them reduced an octave give an exact 5/4 and the meantone comma is tempered out. In superpyth four fiths reduced an octave is instead taken to be equivalent to the septimal, supermajor third 9/7. Two fourth then give the harmonic seventh 7/4. In quarter-comma superpyth  each fifth is sharpened by a quarter of the archytas comma 64/63, the difference between two fourth of 4/3 and a harmonic seventh of 7/4 then tempered out and fourth fifths reduced an octave giving a pure 9/7. Quarter-comma meantone can be well approximated in 31edo (equal divisions of the octave), and quarter-comma superpyth in 22edo. Diatonic notes in Meantone are 5-limit (subgroup 2.3.5), where chromatic intervals may be septimal (7-limit), i.e. the augemented sixth is 7/4 and the diminished fourth is 9/7. Diatonic notes in superpyth are of the 2.3.7 subgroup, with major and minor thirds at 9/7 and 7/6 respectively. Chromatic intervals may be 5-limit, ie an augmented second of 5/4 and a diminished fourth of 6/5. Using a gamut of Ab-C# (traversed by fifths - the generator), the black notes host the octave species of the 5-limit enharmonic trichord, the 5-note scale: 1/1:5/4:4/3:3/2:15/8, our regular 5-limit M3, P4, P5 and M7. This study is a 5 chord riff that makes use of the 5-limit chromatic intervals of Superpyth[12] (12 notes of superpyth temperament generated by a continuous string of fifths), along with the diatonic intervals. The chords include the diatonic subminor seventh, subminor major seventh and included supermajor seventh, along with the chromatic major and minor seventh chords.

This piece is composed with Ice Bookshop Tuning (Iceface tuning 0.1).
Ice Bookshop Tuning (a.k.a Iceface Tuned Piano 0.1) is my first microtonal tuning that I've had called "Iceface Tuning" until the end of 2012.
But in the beginning of 2013 I made the completely new tuning idea that I show on youtube now(yes, every black key is 50 cents higher one) and I decided to call it Iceface Tuning too, just same as my previous tunings.
I apologize this process was really confusing to those who had been listening to my microtonal pieces from 2007 when I released “The Ice Bookshop” because there had been some different tunings all called Iceeface. 
So from now on, I'll call that previous version of Iceface Tuning “Ice Bookshop Tuning" or Iceface Tuning 0.1.
Here's the tuning of “Ice Bookshop Tuning" (Iceface Tuning 0.1) that you also hear in this piece.

B(around -50cents)
C
D
E(around -50cents)
F
G
A
It's kind of B(-50cents) locrian mode which sounds slightly arabic. But with any scale and microtone my intention is mainly focused on to make detune/chorus sound effect to give impressions like melting ices. Hope you'll enjoy!
