C7 Barre / Movable Chord Shapes

Below you’ll find two other ways of playing a C7 guitar chord. They’re both ‘barre chords’–sometimes known as a bar chords–in which the first finger is placed over the strings to hold down the notes on more than one string.

The first C7 chord is based on the open position A7 chord, but played 3 frets higher with a barre.

Dominant Seventh Chords

The full name for a C7 chord is ‘C seventh’ (or, to be even more precise, C dominant seventh).

Seventh chords contain 4 notes (in guitar chords each note may appear more than once in different octaves).

The notes are: The root note, the major third, the fifth, and the minor 7th.

The first three notes are the same as those in a major chord. The addition of the minor 7th note gives the seventh chord its characteristic ‘expectant’ sound.
