I added the following scale to the Gallery of 12-tone Just Intonation Scales on the xenwiki, so if Graham doesn't like it being called his scale now is the time to object.


! bluesji.scl

7-limit JI version of Graham Breed's Blues scale
 12

 27/25
 10/9
 5/4
 35/27
 4/3
 35/24
 40/27
 81/50
 5/3
 140/81
 35/18
 2/1

This scale is interesting in part because though it has only 12 notes, it wants to be ragismic tempered, tempering out 4375/4374. Here's a ragismic version:

 835.39613
 884.28554
 947.14337
 1151.11058
 2/1

It has a major triad on 4, 5 and 10; a minor triad on 1, 2 and 9; a supermajor triad on 4, 10 and 11; and a subminor triad on 2, 7 and 9.
