B maj7 Chord on Puerto Rican Cuatro
Play B maj7 on Puerto Rican Cuatro: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The B maj7 chord is a major seventh — a lush, jazzy extension of the major triad. It is built from the notes B, D#, F#, A#. This page shows how to play B maj7 on Puerto Rican Cuatro with clear fretboard diagrams and suggested finger positions.
The B string ring open in the lowest shape, with the remaining notes fretted at fret 1 over a 2-fret stretch. The G string stays silent, so 4 of 5 sound. The root is the B string itself. It sounds from F#3 up to D#4. 4 voicings are charted, the highest starting at fret 7.
Puerto Rican Cuatro is strung in five courses of two, the lower two paired an octave apart, so each stopped note here sounds as two — which is why the shape rings thicker than the same grip on a single-strung instrument.
Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on B or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
