Locrian ♮2 scale in F# on cavaquinho
Locrian ♮2 scale in F#: F#, G#, A, B, C, D and E, the degrees 1–2–b3–4–b5–b6–b7. The box shown is in open position, from the open strings up to fret 4; the lowest tonic sits on the 4th string, fret 4, and the hand stays put in the region, with no position shift.
On the cavaquinho, four steel strings pack the scale into a short, bright space — there is nowhere for a note to hide. Its four steel strings give a bright, sharp attack that cuts through the mix and drives the beat.
Once the shape is memorized, play the box in thirds: the real memory test.
