C 7 Chord on Viola
Play C 7 on Viola: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.
The C 7 chord is a dominant seventh — a major triad with a flat seventh that pulls strongly toward resolution. It is built from the notes C, E, G, A#. This page shows how to play C 7 on Viola with clear fingerboard diagrams and suggested finger positions.
The shape nearest the nut leaves the C and G strings open and takes the rest in position 1, reaching across 2 positions. The root is the C string itself. It sounds from C3 up to A#4. 2 voicings are charted, the highest starting in position 12.
Viola 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 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.
