C Major 7 Guitar Chord

Cmaj7 is a smooth, spacious extension of C major. The open B adds colour without making the shape harder than a basic C chord.

Why this shape works

Removing the first finger from C major reveals the major seventh B, producing a soft unresolved shimmer.

Clean fingering tip

Compare C and Cmaj7 by lifting only the first finger. Train your ear to recognise the change from root to major seventh.

Fix it fast

Common mistake

The open B and high E must ring. Keep the second finger arched above both strings.

Check every string

Pick from the lowest included string to the highest. A note should either ring clearly or be deliberately muted. Accidental half-muted strings are what make a chord feel weak.
