Small diesic scales

These are related to the samll diesic (126/125 and 1728/1715) linear
temperament. The first is a Fokker block, from the commas <10/9, 126/125,
1728/1715>; the Scala file I present here may be copied and pasted.

We have 18 intervals, 8 triads, and no tetrads; more specifically we get

1-6/5-7/5 and 1-7/6-7/5 chords: roots on degrees 0,6,8,9

1-6/5-7/5-5/3 and 1-7/6-7/5-5/3 chords on degrees 0,9

If we temper this by the 120-et (which is does a good job for small
diesic and makes the scale degrees into nice round numbers in terms of
cents) we get the 11-note small diesic MOS, with generator 31/120:

We now have 34 intervals, 33 triads, and 2 tetrads; the tetrads occur on
degree 7, which might serve as a tonic.

50 intervals, 40 triads, 6 tetrads. There are four more tetrads if we are
willing to count those off by 2401/2400, which is less than a cent.

Either of these, when tempered by the 12-et. gives us the 19-note small
diesic MOS:
