Harmonization
of the degrees of the minor scale

Harmonization of the chords
of the natural minor scale.

The minor scale can be divided into three models, as you can see in the minor scales section. The first model, the natural minor scale, is also the relative minor of the major scale, and therefore the chords (both of three and four notes) come from the third harmonization of the minor scale. For example, in A minor (the relative minor of C major), the first degree (Am) of the minor scale was the sixth in the relative major. The second degree in the minor key was the seventh in that major, and so on. The modes remain the same.

Harmonization of the chords
of the harmonic minor scale

The rules analyzed in the harmonization of the major scale are identical to the minor harmonic scale as well as for the minor melodic scale. You therefore need to establish what chords, and the relative modes, will also be created. Having different interval sequences in the various scales, the modes on which the chords come from will also be different. The names of the modes, with respect to the major scale, change according to the scheme seen below.

I°	Ipoionian 6b
II°	Dorian 2b 5b
III°	Ionian aumented
IV°	Lydian minor
V°	Mixolydian 6b 9b
VI°	Eolian harmonic
VII°	Superlocrian diminished

The names that are given to the modes have very precise meanings. For example, observing the mode that comes on the second degree of the minor harmonic scale, the name that results is dorian 2b 5b. This scale is in fact similar to the dorian mode in the major scale that carries the same root, where the second (2b) and the fifth degrees (5b) are lowered by a half-step. In the table below we can see the modes and names in the harmonization of the minor harmonic scale. The root that is developed is C, therefore seen as minor harmonic C.

Harmonization of the chords
of the minor melodic scale

As seen in the section dedicated to the minor melodic scale, the difference between the minor harmonic and the minor melodic is only one note. The names of the modes, with respect to the minor harmonic scale, changes according to the scheme below.

I°	Ipoionian
II°	Dorian 2b
III°	Lydian aumented
IV°	Lydia 7b
V°	Mixolydia 6b
VI°	Locrian #2
VII°	Superlocrian

The underlying table develops the harmonization of the minor melodic scale of C.
