F add9 Chord on Cello
Play F add9 on Cello: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The F add9 chord is an added-ninth chord that layers in a ninth without the seventh for an open, modern sound. It is built from the notes F, G, A, C. This page shows how to play F add9 on Cello with clear fingerboard diagrams and suggested finger positions.
The shape nearest the nut leaves the G and A strings open and takes the rest in position 3, reaching across 3 positions. F falls on the C string. It sounds from F2 up to A3.
Cello is bowed, with a bare fingerboard and no fixed stops, so this is really a double-stop study: two strings at a time speak cleanly, and the full stack is rolled rather than sounded at once.
Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on F 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.
