For example, the added accidental in C harmonic major, A ♭ (shown in first image), is enharmonically equivalent to the added accidental, G ♯, in the relative harmonic minor of C major, A harmonic minor. 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. 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. 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 also be considered a synthetic scale, primarily used for implying and relating to various altered chords, with major and minor qualities in each tetrachord. The B ♭ harmonic major scale may be derived from the E ♭ melodic minor scale with a raised fourth: E ♭ F G ♭ A B ♭ C D. The B harmonic major scale can also be obtained from the B harmonic minor scale, which is B C ♯ D E F ♯ G A ♯, by raising the D to D ♯. Notice the sixth note in the sequence is lowered, from G ♯ to G.

Harmonic minor contains the same types of seventh chords, but in a different order. Below are the mode names, their degrees, and the following seventh chords that can be built using each modal tonic or degree of the parent mode as the root: a major seventh chord, a half-diminished seventh chord, a minor seventh chord, a minor major seventh chord, a dominant seventh chord, an augmented major seventh chord, and a diminished seventh chord. The harmonic major scale has its own set of modes, distinct from the harmonic minor, melodic minor, and major modes, depending on which note serves as the tonic.
