The Appeal and Usage of Harmonic Minor Scale

What is the Harmonic Minor Scale?

The harmonic minor scale is a natural minor scale with the 7th degree raised by a half step. This allows the formation of a dominant chord (V7) with strong resolution in minor keys.

The most distinctive feature of this scale is the augmented 2nd interval (1.5 steps) between the 6th and 7th degrees. This unique interval creates an exotic sound loved in Middle Eastern music, classical music, and even neoclassical metal.

Scale Structure

The scale follows the pattern: whole-half-whole-whole-half-augmented 2nd-half.

Characteristic Sound

The augmented 2nd interval between the 6th and 7th degrees creates the exotic and dramatic sound unique to this scale. This sound is frequently heard in classical music pieces in minor keys.

Practical Applications

Over V7 Chords

Use over the dominant seventh chord in minor keys (e.g., E7 in the key of Am) for smooth resolution to the tonic.

Neoclassical Phrases

In neoclassical metal, exemplified by Yngwie Malmsteen, high-speed arpeggios and sequence phrases using this scale are standard.

Exotic Melodies

Effective for creating Middle Eastern or Spanish-flavored melodies. Also commonly used in flamenco guitar.

Comparison with Natural Minor

While natural minor expresses calm sadness, harmonic minor has a more dramatic and tense sound. Using both expands your expressive range significantly.

Effective Practice Methods

• Practice 3-note-per-string patterns to cover the entire fretboard
• Consciously practice over dominant seventh (V7) chords
• Repeatedly practice phrases containing the augmented 2nd interval
• Copy phrases from classical music or neoclassical metal

Summary

The harmonic minor scale brings strong resolution and dramatic sound to minor key compositions. It is a highly versatile scale used across classical, flamenco, metal, and various other genres.
