Jazz minor scale

Melodic Minor upward (short MMA) denotes a scale used mainly in jazz, which corresponds to the upward variation of the melodic minor scale used in the classical period. MMA has the same Tonvorrat as the acoustic scale, and is the fifth mode within the Heptatonia Secunda.

It is formed by the sixth and seventh intervals of a natural minor scale are hochalteriert. The rest of the scale remains unchanged. This is a semitone between the second and third, and between the seventh and eighth stage, the other intervals are whole steps. It is striking that MMA is a minor scale, but ( the major seventh ) has a leading tone to the tonic. This feature it shares with the harmonic minor scale and the Gypsy Minor, but is in contrast to those without hiatus steps. This major seventh is the major third of the dominant, which would not develop dominant diagram function without these major third. The emergence of these major third is derived analogous to the formation of the major third in the double dominant or the diminished seventh chord.

Typically, it is the tonic in a jazz minor cadence. The corresponding chords are XM6 or Xm maj7 and not XM7. Improvised there is no minor seventh.

On the steps of the MMA - scale, many commonly used scales are based. For example, the altered scale is the seventh stage of Melodic Minor upward.
