C 9 Chord on Mandocello
Play C 9 on Mandocello: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The C 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 C, D, E, G, Bb. This page shows how to play C 9 on Mandocello with clear fretboard diagrams and suggested finger positions.
The C and D courses ring open in the lowest shape, with the remaining notes fretted at fret 3 over a 5-fret stretch. The root is the C course itself. It sounds from C2 up to E4.
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 C 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.
