Locrian mode in B on cavaquinho
Locrian mode in B: B, C, D, E, F, G and A, the degrees 1–b2–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 3rd 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.
Practice it tonic to tonic: hearing degree 1 at both ends anchors the scale's sound.
