Progressions in Db — Puerto Rican Cuatro (Standard)

Db major harmonises to Db – Ebm – Fm – Gb – Ab – Bbm – C°; C# minor to C#m – D#° – E – F#m – G#m – A – B. 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.
