Because there are three different minor scales, it is possible to come up with different sets of chords for a minor key by building chords on the notes of each different minor scale. Each variation to the notes of the scale alters the quality of chords built on the scale. The letter names of the chords remain the same, but the chord type may change. The scale tone chords derived from the A harmonic minor scale are shown in the next example. Notice that chord III is now augmented instead of major, and also that chord V is major instead of minor and chord VII is diminished instead of major. These changes are all brought about by the raising of the 7th degree of the scale from G to G#.
The following example demonstrates a melody and chord progression created from the A harmonic minor scale. Try playing it on the keyboard using the right hand to play the melody and the left hand to play the chords, or play the melody on your instrument and have a friend play the chords.
