Overview

Hungarian minor scale kind.

HungarianMinorScaleKind defines the Hungarian minor scale (also called Gypsy minor or Double Harmonic Minor), a minor scale with two augmented seconds creating an exotic, Eastern European sound.

Pitch Structure

7 diatonic degrees plus extended harmony:

Scale Degrees (lowercase for minor quality):

• i (tonic): Root (0 semitones)
• ii (supertonic): Major second (2 semitones)
• iii (mediant): Minor third (3 semitones)
• iv (subdominant): Augmented fourth (6 semitones) ← CHARACTERISTIC (#4)
• v (dominant): Perfect fifth (7 semitones)
• vi (submediant): Minor sixth (8 semitones)
• vii (leading): Major seventh (11 semitones)

Two Augmented Seconds

• Between III and IV (b3 to #4): 3 semitones
• Between VI and VII (b6 to 7): 3 semitones

Musical Character

The Hungarian minor scale:

• Dramatic, passionate, exotic
• Common in Hungarian and Romani music
• Used by Liszt, Brahms, and other Romantic composers
• Creates a distinctive "gypsy" sound

Usage

a_hung_min.tonic  # A (69)
a_hung_min.iv     # D# (75) - augmented fourth
a_hung_min.vii    # G# (80) - major seventh
