Double Harmonic and Related Scales

Double harmonic major has the formula:

1-flat 2-3-4-5-flat 6-7

From C:

C-D flat-E-F-G-A flat-B-C

D flat-E and A flat-B are augmented seconds. Each spans three semitones across adjacent letter names.

The major third E and leading tone B keep clear major and tonic relationships while flat 2 and flat 6 create the two wide steps.

Start with C major: C-D-E-F-G-A-B.

Lower degree 2 from D to D flat. Lower degree 6 from A to A flat.

No other degree changes. Comparing the two scales from the same tonic makes both altered positions easy to hear.

Hungarian minor has the formula:

1-2-flat 3-sharp 4-5-flat 6-7

From C:

C-D-E flat-F sharp-G-A flat-B-C

It contains augmented seconds from E flat to F sharp and from A flat to B.

Its minor third separates it from double harmonic major, and sharp 4 separates it from harmonic minor.

Phrygian dominant has the formula:

1-flat 2-3-4-5-flat 6-flat 7

From C:

C-D flat-E-F-G-A flat-B flat-C

It is the fifth mode of F harmonic minor. Its major tonic triad, flat 2 and flat 7 make it useful over dominant-type harmony and tonic drones.

It has one augmented second, D flat-E, while double harmonic major also has B natural and a second augmented step A flat-B.

Terms such as Gypsy scale, Byzantine scale or Oriental scale have been used inconsistently across books, regions and eras.

One source may use a label for Hungarian minor, another for double harmonic major. The words can also reduce several musical traditions to an outsider stereotype.

Use a specific formula and established scale name. When discussing music from a particular tradition, learn its own tuning, melodic rules, ornamentation and terminology.

No. A seven-note equal-tempered scale lists pitch classes. It does not capture tuning inflections, characteristic phrases, rhythm, form or performance practice.

Related pitch collections appear in several traditions under different names and tuning systems. Similar notes do not prove one universal musical language.

State the exact collection used in the piece and avoid assigning geographic meaning from the scale alone.

In C double harmonic, the tonic triad is C-E-G: C major.

Degree 2 forms D flat-F-A flat: D-flat major. Degree 4 forms F-A flat-C: F minor.

The stacked notes B-D flat-F on degree 7 contain the diminished fifth B-F, but B to D flat is a diminished third, so they do not form a regular diminished triad. The scale also produces less common seventh chords.

Build each chord directly from the written notes because familiar major-key patterns do not apply.

Play the notes on either side slowly and hear the three-semitone leap as two adjacent scale degrees.

Approach the leap in both directions. In C double harmonic, compare D flat-E and A flat-B.

Do not fill the gap automatically with chromatic notes; that changes the scale. Use ornamentation only when it fits the musical style being played.

A tonic drone makes their interval patterns clear. Riffs can emphasize flat 2 against the tonic or outline the tonic triad before crossing an augmented second.

Functional progressions may use the leading tone to reach the tonic. Other pieces treat the collection modally over repeated harmony.

Choose chords from the scale and watch for close semitone clusters in low registers.

Hold C and play C major. Lower D and A to create C double harmonic.

Next, compare B natural with B flat to move between double harmonic and Phrygian dominant.

For Hungarian minor, begin with C harmonic minor and raise F to F sharp. Name the changed degree and both augmented seconds.
