Progressions in B — Puerto Rican Cuatro (Standard)

B major harmonises to B – C#m – D#m – E – F# – G#m – A#°; B minor to Bm – C#° – D – Em – F#m – G – A. Each chord links to its Puerto Rican Cuatro (Standard) grips, so a whole key becomes a short list of hand positions.

Most of this repertoire lives on three or four of these chords, and the interesting work is in what happens between them: the pick states a line, the grip lands underneath it, and the next change arrives before the ear has finished the last one.
