File:Locrian Fugue.mp3

This is a short fugue I wrote in the Locrian mode at Aura's suggestion (and to go with my Mixolydian and Phrygian Fugues. -- I also have a Dorian Fugue I wrote ages ago.) It is in 12 EDO. I tried it in 17, 53, 55, 31, and 19 EDO as well, and 12 EDO definitely sounds best.

I suspect the reason is as follows: The subject (in B Locrian) begins B3 G4 F4 E4 D4, and I think I want it to be heard as an elaboration of a B3 D4 F4 G4 5:6:7:8 tetrad, which only works in a Dominant temperament like 12EDO. I was not consciously thinking of this when writing this. I was just composing by ear, guided by standard early common practice counterpoint heuristics.
