Lesson 03 – Harmonic Minor, Melodic Minor, and Scale Modes
The Harmonic Minor and Melodic Minor scales are originated by alterations in the Natural
Minor scale. These alterations will not only originate new scales, but also new chords and
harmonic possibilities that are often explored in classical, jazz, and contemporary music.
Learning these scales and the chords contained in them will greatly expand your musical
vocabulary.
The Harmonic Minor Scale
The Harmonic Minor scale comes from the alteration of the 7th degree of the Natural Minor
Scale. On the Natural Minor Scale, the 7th degree of the scale is a m7. The Harmonic Minor
scale will raise the 7th degree by a half-step (M7). The intervals for the Harmonic Minor
scale are R, M2, m3, P4, m6, M7, and P8, or 1, 2, b3, 4, 5, b6, 7, 8.

The Melodic Minor Scale
The Melodic Minor scale comes from the alteration of the 7th degree of the Harmonic Minor
Scale. On the Harmonic Minor Scale, the 6th degree of the scale is a m6. The Melodic Minor
scale will raise the 6th degree by a half-step (M6). The intervals for the Harmonic Minor
scale are R, M2, m3, P4, M6, M7, and P8, or 1, 2, b3, 4, 5, 6, 7, 8.

Major/Natural Minor, Harmonic Minor and Melodic Minor Tertian Chords
By stacking thirds in succession, we can form the triad (R-3-5), the seventh, and the chord
extensions (9, 11, 13) of the diatonic scales. By applying this process to each degree of a
given scale you will map all the possible tertian chords of a given scale. It is important to
notice some of these possible chords will not sound good are not used in practical music for
reasons we will discuss later. Here are some examples of possible tertian chords within
these scales:
C Major / A Natural Minor

C Harmonic Minor

C Melodic Minor
Figure 5 – C Melodic Minor tertian chords
Practicing Scales and Modes
Now that you know how the main diatonic scales are built, practice the major/minor,
harmonic minor, and melodic minor modes. Dividing the diatonic scales in 7 modes with
7 different shapes is a helpful system to memorize these scales across the fretboard and
to them in tonal and modal improvisation.
