My Guitar Notes

E locrian scale

The seventh mode of the major scale: a minor scale with a flattened second and a flattened fifth. It is the only mode whose tonic triad is diminished, which is why it is rarely used as a key centre.

Positions on the guitar

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

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.
