Scale of the Day: A Octotonic-1
The intervallic content of the A Octotonic-1 Scale. Having the intervals of the scale laid out like this makes clear the alternating or static quality of intervals of the octotonic scale. One row has alternating major/minor seconds. Then next is all minor thirds. Then there's alternating major/augmented thirds. This is followed by a row of tritones only. Then alternating augmented/perfect fifths. Then major sixths only. Then alternating major/minor sevenths leading into the harmonically equivalent octave. It's this quality that colors the octotonic scale and makes it a good transition harmony for modulating between key centers.
