Progressions in G — Puerto Rican Cuatro (Standard)

G major harmonises to G – Am – Bm – C – D – Em – F#°; G minor to Gm – A° – Bb – Cm – Dm – Eb – F. 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.
