Hungarian minor scale
From Wikipedia, the free encyclopedia
The Hungarian minor scale is a type of combined musical scale. It is akin to the harmonic minor scale, except that it bears a raised fourth. Its tonal center is slightly ambiguous, due to the plentiful amount of half steps. Also known as Double Harmonic Minor, or Harmonic Minor #4, it figures prominently in Eastern European music, particularly among the gypsy population. Melodies based on this scale have an exotic, romantic flavor.
A Hungarian minor scale in the key of C would proceed as follows: C D Eb F# G Ab B.
Its scale degrees are 1 2 b3 #4 5 b6 7, and its step pattern is W H m3 H H m3 H.
Chords that may be derived from the scale are Cm, D7b5, Eb+, G, Ab7 and Bm6.
