G7 Guitar Chord
G Dominant 7th · G–B–D–F
G7 is the G dominant 7th chord: G–B–D–F. Its sound is bluesy and unresolved — the dominant 7th wants to pull somewhere, which is why it powers blues turnarounds and V chords.
G7 is the V7 chord in the key of C, which is where its pull comes from — the ♭7 (F) rubs against the major 3rd and demands resolution. In a 12-bar blues in G, every chord (I7, IV7, V7) gets this dominant treatment.
The easiest way to play G7 is the open-position shape (3 2 0 0 0 1, low E string to high E string), which uses open strings and stays in the first few frets. Below you'll find 6 ways to play it across the neck, from open position to barre and shell voicings, with the theory behind the chord and the progressions it lives in.
