Scale of the Day: B Dorian diminished 4


The intervallic content of the B Dorian diminished 4 Scale. Notice the wave of augmented and diminished intervals introduced by the diminished fourth alteration. Yet in equal temperament these happen to be the same size as many enharmonic major/minor intervals. This discrepancy between spelling and sound is a strong indication of what harmonies are not available in standard equal temperament.
