Scale of the Day: F Locrian no 4
The F Locrian no 4 Scale as one would find it on any conventionally tuned, equal tempered instrument. The missing fourth degree adds a level of ambiguity to the diminished fifth. With an equal tempered system it is probable that the ear will cognitively resolve it as an augmented fourth. As a composer, the standard issues of resolution that manifest with the odd tonal gravity of the diminished fifth are ever present and the challenge is to not treat the diminished fifth as a substitute for the missing fourth degree.
