Melodic minor upwards
Melodic minor upward ( MMA for short ) refers to a scale used primarily in jazz , which corresponds to the upward variant of the melodic minor scale used in classical music . MMA has the same set of tones as the acoustic scale and is the fifth mode within the Heptatonia Secunda .
It is formed by the sixth and seventh of a natural minor scale hochalteriert be. The rest of the scale remains unchanged. This means that there is a semitone between the second and third and between the seventh and eighth steps , the other intervals are whole steps . It is noticeable that MMA is a minor scale, but still has a leading tone to the root (the major seventh ). It shares this property with the harmonic minor scale and the gypsy minor , but in contrast to these, it does not have hiatus steps . This major seventh is the major third of the dominant, which would not develop a dominant function without this major third. The origin of this major third is derived analogously to the origin of the major third in the double dominant or the diminished four-chord.
Typically it forms the tonic in a jazz minor cadence . The associated chords are Xm6 or Xm maj7 and not Xm7. It is improvised without a minor seventh.
Many commonly used scales are built upon the steps of the MMA scale. For example, the altered scale is the seventh degree from Melodic Minor upwards.
