E Locrian ♮2 ♮3 Scale
E Locrian ♮2 ♮3 contains 7 notes: E, F♯, G♯, A, B♭, C, D. It has 2 sharps: F♯, G♯. The step pattern is W–W–H–H–W–W–W.
Also known as "Arabian," this is a surprisingly usable Locrian variant. Restoring the natural 2nd and major 3rd transforms Locrian from nearly unusable into a dominant-quality scale with a Middle Eastern edge.
The formula is 1, 2, 3, 4, b5, b6, b7. It sounds like Mixolydian with a b5 and b6 — the major 3rd gives it dominant quality while the b5 prevents full stability. In Middle Eastern music, it provides an instantly recognizable exotic flavor. It works over dominant chords with altered fifths.
To get a true "Arabic" feel, add rapid microtonal string bends, pre-bends, or whammy bar flutters to simulate quarter-tones — the guitar's fret system can't natively produce the microtonal inflections of actual Middle Eastern music, but these techniques get close. Use it over 7b5b13 or similar altered dominant chords.
