The fifth mode of the harmonic minor scale: a major third with a flattened second, sixth and seventh. The augmented second between the flat second and the major third is what gives the scale its characteristic sound.

Positions on the guitar
The five windows below are computed, not copied from a shape chart. The script locates the lowest
occurrence of A 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 0–2
Root on the 5th string A2 at fret 0. 11 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.
