The ascending form of the melodic minor scale: the natural minor scale with a raised sixth and seventh. The traditional classical descending form is the natural minor; in jazz practice the ascending form is used in both directions, which is why it is also called the jazz minor.

Positions on the guitar
The five windows below are computed, not copied from a shape chart. The script locates the lowest
occurrence of Ab on each of the five upper strings within the first twelve frets and takes a
five-fret window centred on it. Because a scale repeats every twelve frets, these five windows cover
the whole neck; the same sequence returns an octave higher. The positions are numbered from the lowest
fret upwards, so position 1 is always the window nearest the nut and position 5 the window nearest the
twelfth fret.
Position 1 — frets 0–3
Root on the 3rd string G3 at fret 1. 13 notes of the scale inside this window.
Read the grid as a chord diagram: the top row is the first string. Degrees appear in the
notes and degrees table above; a filled cell is a note of the scale, and the shaded cell is the tonic.
