Play B Dim on Puerto Rican Cuatro: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The B Dim chord is a diminished chord built from stacked minor thirds, often used as a passing or leading chord. It is built from the notes B, D, F. This page shows how to play B Dim on Puerto Rican Cuatro with clear fretboard diagrams and suggested finger positions.
The shape nearest the nut leaves the B and D strings open and takes the rest at fret 1, reaching across 4 frets. The root is the B string itself. It sounds from F3 up to B4.
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.
