Athenian Scale
The Athenian Scale 1 2 ♭3 4 5 6 7 (Aka. Melodic Minor, Ascending Melodic Minor) is the first mode of Melodic Minor.
Melodic minor is a variation of the natural minor scale - Aeolian - where the sixth and seventh degrees are natural. The middle step between Athenian and Aeolian is Appalachian (harmonic minor) as it's also a variation of minor, though with only the minor seventh turning into a major one.
This scale's paramode is the Cappadocian scale, which is simultaneously it's second mode.
