B Major Chord on Mandolin
Play B Major on Mandolin: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The B Major chord is a bright, stable major triad — one of the first chords most players learn. It is built from the notes B, D#, F#. This page shows how to play B Major on Mandolin with clear fretboard diagrams and suggested finger positions.
The lowest shape sits at fret 2 and spans 3 frets, with no open strings in it. B falls on the G string. It sounds from B3 up to F#5. 2 voicings are charted, the highest starting at fret 4.
Mandolin is strung in four courses of two, each pair tuned in unison, 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.
