The sixth mode of the major scale. Identical in pitch content to the natural minor scale; the mode name is used when the set is treated as a rotation of a parent major scale.

Positions on the guitar

The five windows below are computed, not copied from a shape chart. The script locates the lowest occurrence of Bb 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

Root on the 5th string A2 at fret 1. 12 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.
