Why it sounds like that

Its altered interval creates tension while the supplied root and remaining tones stay fixed. The intervals are 1, ♯2, 3, 5, ♯5, 7, with step pattern 1½, H, 1½, H, 1½, H. Compare with F♯ harmonic minor to hear the raised fourth. The scale contains augmented triads F♯–A♯–C♯♯ and A♯–C♯♯–E♯.

When to use it

Use F♯ augmented over F♯ major or F♯ minor chords for a raised fifth. It fits F♯ major or F♯ minor. Also use over A augmented and C♯ augmented chords.

Which position to practise

Practise Box 1 first. The root on string 6, fret 2 gives a low anchor and prepares Box 2.
