Harmonic major scale on C

In music theory, the harmonic major scale is a musical scale which found occasional use during the common practice era and is now often employed, particularly in jazz. In George Russell's Lydian Chromatic Concept it is called the Lydian Diminished scale.^[1]

It may be considered as a major scale with the sixth degree lowered, Ionian ♭13^[2], or the harmonic minor scale with the third degree raised. It is also a mode of the inversion of the harmonic minor scale.^{[dubious – discuss]} It complements the following chords types Dom 7 ♭9, Dom 7 ♭9 ♯9(♯5), and dim.^[3]

For example, an A major scale consists of the notes: A B C♯ D E F♯ G♯; whereas an A harmonic major scale consists of the notes: A B C♯ D E F G♯. Notice the sixth note in the sequence is lowered, from F♯ to F. The A harmonic major scale can also be obtained from the A harmonic minor scale, which is A B C D E F G♯, by raising the C to C♯. The E harmonic major scale may be derived from the A melodic minor scale with a raised fourth: A B C D# E F# G#.^[4]

Harmonic major scale on C

The harmonic major scale may also be considered a synthetic scale, primarily used for implying and relating to various altered chords, with major and minor qualities in each tetrachord.^[5] Thus the musical effect of the harmonic major scale is a sound intermediate between harmonic minor and diatonic major, and partaking of both. The harmonic major scale may be used in any system of meantone tuning, such as 19 equal temperament or 31 equal temperament, as well as 12 equal temperament.

One interesting property of this scale is that for any diatonic scale, there is a relative major or minor mode, and if each of these is made harmonic major or harmonic minor, the accidental required in each "harmonic" scale is actually the same note spelled enharmonically. For example, A-flat in C harmonic major and G-sharp in A harmonic minor; i.e., A harmonic minor is an "enharmonic mode" of C harmonic major.^{[dubious – discuss]}

Harmonic major scale in thirds

The harmonic major scale is one of the five proper seven-note scales of equal temperament, and while less often used than the diatonic major, diatonic (or natural) minor, harmonic minor or ascending minor scales, belongs to the same family and can be regarded as a natural member of the diatonic system of scales. Like those other scales, it has a complete circle of thirds; starting from the tonic the pattern is MmmmMMm, where M is a major third and m is a minor third.
