Chord Voicings — Puerto Rican Cuatro (Antiguo A-D-G-C-F)

The Puerto Rican Cuatro (Antiguo A-D-G-C-F) chord reference: pick a root, then any of 62 qualities, and every charted grip arrives on A-D-G-C-F with its frets, its fingers, and audio.

Ten strings in five doubled courses is a lot of instrument for a chord, and the doubling is the point: each course answers twice, so a grip rings like a small twelve-string and carries over a room. The Puerto Rican instrument is a lead voice first — a cuatrista states the tune with a pick and drops the full grip in between phrases, which is why these charts name the fret and finger for every course rather than only the shape.

Every adjacent pair on A-D-G-C-F climbs, so the open strings run straight from bottom to top across a minor thirteenth.
