The Hungarian minor scale, double harmonic minor scale, or Gypsy minor scale is a type of combined musical scale. It is the fourth mode of the double harmonic scale. It is the same as the harmonic minor scale, except that it has a raised fourth scale degree 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. This scale is obtainable from the double harmonic scale by starting from the fourth of that scale, so the C Hungarian minor scale is equivalent to the G double harmonic scale.
