F# locrian major

The major locrian scale, catalogued in older collections as the arabian scale, starts like a major scale (natural 2nd and 3rd, 4th) and collapses into locrian from the flat 5th upward. The bright opening makes the diminished top half hit harder. It also functions as the fifth mode of the neapolitan major scale, and suits dominant chords with both altered 5ths.

it consists of these notes and degrees:

tip
  • Start lines like plain F# major (II, III, IV all natural), then let the collapse from b5 (C) onward land the tension; the contrast is the scale.
  • Catalogued in older books as the arabian scale: over a root drone, the bright-then-diminished shape reads instantly exotic.
  • Use it over a dominant chord with altered 5ths; the major 3rd (A#) and flat 7th (E) hold the center while b5 (C) and b6 (D) pull down.
  • The natural 4th (B) beside the flat 5th (C) is a free chromatic slide; use it as the pivot between the scale's two halves.

How to play F♯ locrian major on guitar

Four open strings fall in this key: both E strings as the minor seventh, the open D a minor sixth above the tonic and the open B a perfect fourth. Not one of them is the tonic or fifth, which lets them sit as colour under a fretted line but never as a pedal. Low E holds the lowest root at fret 2. EM answers to the bVII, meaning that triad is playable straight off the open sixth string.
