Chord & FretDouble harmonic (Byzantine) on cavaquinho (C)
Double harmonic (Byzantine) in C: C – Db – E – F – G – Ab – B. On the cavaquinho, four steel strings pack the scale into a short, bright space — there is nowhere for a note to hide. The box shown runs from fret 1 to 4; the lowest tonic sits on the 2nd string, fret 1, and the hand stays put in the region, with no position shift. 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.
Read the dots by degree: 1 is the tonic (highlighted); the rest follow the scale's formula.
