The seven-note diatonic scale the tonal system is built on. Its step pattern is whole, whole, half, whole, whole, whole, half. The Ionian mode is identical in pitch content.
The reference scale for Western harmony; every key signature on this site is derived from a 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 G 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 3rd string G3 at fret 0. 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.
