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. ! smalldi11.scl ! Small diesic 11-note block, <10/9, 126/125, 1728/1715> commas ! 11 ! 36/35 7/6 6/5 216/175 7/5 10/7 175/108 5/3 12/7 35/18 2/1 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: ! smalldimos11.scl ! Small diesic 11-note MOS, 31/120 version ! 11 ! 40.0 270.0 310.0 350.0 580.0 620.0 850.0 890.0 930.0 1160.0 2/1 We now have 34 intervals, 33 triads, and 2 tetrads; the tetrads occur on degree 7, which might serve as a tonic. ! smalldi19a.scl !

Small diesic 19-note block, <16/15, 126/125, 2401/2400> commas ! 19 ! 50/49 21/20 8/7 7/6 6/5 49/40 5/4 48/35 7/5 10/7 35/24 8/5 80/49 5/3 12/7 7/4 40/21 49/25 2/1 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: ! smalldimos19.scl ! Small diesic 19-note MOS, 31/120 version ! 19 ! 40.0 80.0 230.0 270.0 310.0 350.0 390.0 540.0 580.0 620.0 660.0 810.0 850.0 890.0 930.0 970.0 1120.0 1160.0 2/1 82 intervals, 105 triads and 18 tetrads Here is variant 19-note scale containing glumma: ! smalldi19c.scl ! Small diesic 19-note scale containing glumma ! 19 49/48 21/20 15/14 35/32 6/5 49/40 5/4 9/7 21/16 10/7 35/24 3/2 49/32 5/3 12/7 7/4 9/5 35/18 2/1 53 intervals, 45 triads, 8 tetrads Tempering this gives the following: ! smalldiglum19.scl ! Small diesic "glumma" variant of 19-note MOS, 31/120 version ! 19 ! 40.0 80.0 120.0 160.0 310.0 350.0 390.0 430.0 470.0 620.0 660.0 700.0 740.0 890.0 930.0 970.0 1010.0 1160.0 2/1 78 intervals, 94 triads, 16 tetrads ------------------------ Yahoo!
