The harmonic minor scale (or Aeolian ♮7 scale) is a musical scale derived from the natural minor scale, with the minor seventh degree raised by one semitone to a major seventh, creating an augmented second between the sixth and seventh degrees.
Thus, a harmonic minor scale is represented by the following notation:
In Western classical music theory, the minor scale refers to three scale patterns – the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending).
These scales contain all three notes of a minor triad: the root, a minor third (rather than the major third, as in a major triad or major scale), and a perfect fifth (rather than the diminished fifth, as in a diminished scale or half diminished scale).
In music theory, the harmonic major scale is a musical scale found in some music from the common practice era and now used occasionally, most often in jazz. It corresponds to the Raga Sarasangi in Indian Carnatic music, or Raag Nat Bhairav in Hindustani music.
It can be considered a major scale with the sixth degree lowered, Ionian ♭6, or the harmonic minor scale with the third degree raised.The intervals between the notes of a harmonic major scale follow the sequence below:
