How to play the D Dominant 7th chord on guitar
D7 has a distinctive pointed shape on the top strings and a sharp, insistent sound. It resolves naturally to G, which makes the D7–G pair one of the most common cadences in folk, country and early rock.
D Dominant 7th is a dominant seventh: the D triad with a flattened seventh on top — D, F#, A, C. That added note is what gives it its bluesy, unfinished pull.
Finger it one string at a time
- low E string: don't play it.
- A string: don't play it.
- D string: play it open.
- G string: fret 2 with your middle finger.
- B string: fret 1 with your index finger.
- high E string: fret 2 with your ring finger.
Looks like a backwards D major. Makes you want to resolve to G!
What makes this shape awkward
- 2 strings stay silent, so your strumming hand has to start on the right string. Aim the pick rather than sweeping all six.
Where you'll use it
D7 appears in 2 of the play-along progressions in RiffRoute. These are the actual sequences it sits in:
- Delta Turnaround (Texas Blues, 110 BPM) —
A7 → D7 → A7 → D7 → A7 → E7 → D7 → A7 → … - Amber Turnaround (Jazz Standard, 120 BPM) —
Am → D7 → G7 → C7
Chords it's usually played with
In the progressions that use D7, these turn up alongside it most often — learning them together is more useful than learning D7 alone.
Hear it and check yourself
Reading a diagram only gets you so far — the part that decides whether D7 sounds right is whether every string rings cleanly. RiffRoute plays the chord back, listens while you strum it, and tells you which string is buzzing.
