Scale of the Day: D Pythagorean Chromatic - Lydian Mode
The D Pythagorean Chromatic - Lydian Mode - Scale. Starting with the D-natural, tuned upward by 3/2 (701.96 cent) perfect fifths. Since the Pythagorean fifths do not circle around we have the biting dissonance of the 262144/177147 (678.49 cent) diminished sixth between the F-double-sharp and the D-natural. This scale is said to be "Lydian Mode" because it is made up exclusively a tonic and all otonal intervals relative to the tonic.
