Blues 97.5 by Lillian Hearne

12 bar blues in my new tuning system: 97.5c-ET. It's like a squished 12TET, with each semitone at 97.5c. The intonation of 5/4 - major third, 7/5 - tritone and 5/3 - major sixth (and therefore 7/4 and 7/3) is improved from 12TET, but the inverses of these intervals no longer exist and there are no octaves or fifths. The 4/3 - perfect fourth of 97.5c-ET is 10.5c flat of pure, reminiscent of Superpyth temperament, where 2 4/3's give 7/4, tempering out 64/63. 8 semitones gives an accurate 11/7 and 3 an accurate 13/11, extending the system to the 4/3.5/3.7/3.11/3.13/3 subgroup. The chords I used:
1:5/4:7/4:7/3 on C - C:E:Bb:Eb
1:5/4:7/4 on F - F:A:Eb, and
1:5/4:7/4:7/3:(11/4):13/4 on G - G:B:F:Bb:(C#):E
