Scale of the Day: D Sharp Pythagorean Locrian diminished 4


The D Sharp Pythagorean Locrian diminished 4 Scale. In theory, the severely utonal 8192/6561 diminished fourth should shade this scale toward an even darker harmony than the standard Pythagoroean Locrian scale could provide (an already dark scale even if the 4/3 perfect fourth is the "brightest" of the utonal members). In practice, however, at 384.36-cents the 8192/6561 is likely to be interpreted by the contemporary ear - unaware of the 3-limit context - as the otonal 5/4 at 386.31-cents given the mere 1.95-cent difference between them.
