Scale of the Day: A Mixolydian no 4 diminished 5

The A Mixolydian no 4 diminished 5 Scale as one would find it on any conventionally tuned, equal tempered instrument. The equal temperament allows for enormous ambiguity between the major third and diminished fifth - a diminished third that ends up sounding like a major second in this tuning system. This ambiguity is compounded by the augmented second between the diminished fifth and major sixth - an interval that could pass for a minor third.
