The Hungarian minor scale,[2][3][4][5][6]double harmonic minor scale,[7] or Gypsy minor scale[4][8] is a type of combined musical scale. It is the same as the harmonic minor scale, except that it has a raised fourth scale degree[2][3][4][6][7][8] to introduce an additional gap, or augmented second. It is a symmetrical scale with a slightly ambiguous tonal centre, due to the many half steps.
Its step pattern is W, H, +, H, H, +, H, where W indicates a whole step, H indicates a half step, and + indicates an augmented second (three half steps, enharmonically equivalent to a minor third but functionally distinct). In intervallic terms, it would be described as: 1 2 ♭3 ♯4 5 ♭6 7.
The scale contains two augmented seconds,[5] one in each tetrachord.[1] It also contains an augmented fourth between the first and fourth degree.
This scale is one of the few perfectly balanced seven-note subsets of the equally tempered chromatic scale: when its pitches are represented as points in a circle whose full circumference represents an octave, their average position (or "centre of mass") is the centre of the circle.[9]
The scale may be used with minor or m+7 chords.[2][6] See: chord-scale system. Chords that may be derived from the B Hungarian minor scale are Bm(maj7), C♯7♭5, Dmaj7♯5, E♯6sus2♭5, F♯maj7, Gmaj7, G7, A♯m6 and more.
This scale is obtainable from the double harmonic scale by starting from the fourth degree of that scale, so the C Hungarian minor scale is equivalent to the G double harmonic scale.[7]
This scale is sometimes also referred to as "Gypsy Run", or alternatively "Egyptian Minor Scale", as mentioned by Miles Davis who describes it in his autobiography as "something that I'd learned at Juilliard".[11]
An alternative (and less common) version is the asymmetric Aeolian ♯4 scale, the only difference with the Hungarian minor scale being that the 7th degree of the scale is not raised.[12][13] This form of the scale can also be used in the fourth mode and would then be referred to as the Neapolitan scale.
The Pink Panther Theme, originally played in the key of E minor, is noted for its quirky, unusual use of chromaticism which is derived from this scale.[14]
The second section of Klaus Schulze's long composition “Ludwig II” from the album X has a theme built on an ascending Hungarian minor scale.
The song “Worth It” by Fifth Harmony features a saxophone riff written in this scale.
The theme tune from the 1983 animated TV series “Inspector Gadget”[18] uses this scale.
In a song by Will Wood, BlackBoxWarrior - OKULTRA, Will references “A hymn out in Hungarian Harmonic”. Following this lyric is a walk up the Hungarian Minor scale.
Much of the album The Hand of the Wicked One by Wynter Kills was written in the Hungarian Minor scale, with many sections harmonized in Hungarian Minor.
