== Remembering the pitch structure == | |||
The pitch structure is very easy to remember. In 72, 12edo is the Pythagorian ring. Every 6 degrees is the 3-limit. | |||
Then, after each subsequent degree in reverse, a new prime limit is unveiled from it: | |||
-1 degree corrects 5/4 (80/81) | |||
-2 degrees corrects 7/4 (63/64) | |||
+3 degrees corrects 11/8 (33/32) | |||
+2 degrees corrects 13/8 (1053/1024) | |||
+1 degree corrects 17/16 (4131/4096) | |||
