The first mode of the major scale. Identical in pitch content to the major scale; the mode name is used when the scale is being treated as one of the seven rotations of the same set of notes rather than as a key.
Each degree of the scale, its note name in this key, and its distance from the root in semitones.

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 — frets 0–3
Root on the 5th string A2 at fret 1. 15 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.
