The B 7#9 chord is an extended or altered dominant that stacks ninths, elevenths, thirteenths, or chromatic tensions over a dominant-seventh core. It is built from the notes B, C##, D#, F#, A. This page shows how to play B 7#9 on Mandocello with clear fretboard diagrams and suggested finger positions.
The shape nearest the nut leaves the D and A courses open and takes the rest at fret 8, reaching across 4 frets. B falls on the C course. It sounds from B2 up to A3.
Mandocello is strung in four courses of two, 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.
