How to play the D7 guitar chord
Open D7 Chord
The open D7 chord is the most common D7 chord on guitar, and is a common guitar chord for beginners.
This is a commonly seen substitute for the common open D guitar chord.
D7 Guitar Chord (E7 Shape)
This is arguably the most difficult D7 guitar chord shape, because it’s a barre chord.
Don’t let that hold you back from learning this chord, though. Due to it’s barre nature, and the bass note being the root, this chord is easy to move around from one 7th chord shape to another.
D7 Guitar Chord (C7 Shape)
This is a commonly used guitar chord with the Travis picking style.
It’s also common in country and bluegrass guitar.
If you already know your open position C7 guitar chord, just move it up a whole step to get this shape.
D7 Guitar Chord (A7 Shape)
This is another barre chord, not quite as common as it’s earlier barred shape brother.
Despite that fact, this chord shape is a no-brainer if you’re sticking around the fifth fret of the guitar.
This shape is derived from an open A7 chord.
D7 Guitar Chord (Jazz Shape)
I call this the jazz shape because it’s so easy to move the intervals, such as the root or fifth, to new intervals in order to create unique harmonies.

What is the difference between D and D7 on guitar?
The D7 chord differentiates itself from a D chord by incorporating an extra note, the C note, which is the flattened 7th interval.
The addition of a flat 7th can cause tension in music, which is usually resolved by moving to a tonic.
Is D7 and D Major 7 the same?
D7 and D Maj7 are not the same chord.
D7 is a major triad plus a flat 7th, and D Maj7 is a major triad plus a major 7th.
This gives D7 the notes D-F#-A-C and D Maj7 the notes D-F#-A-C#.
What scale goes with D7?
As a general rule the D major pentatonic scale and D Mixolydian both go with D7.
Can I play D7 instead of D?
You can play a D7 chord instead of D, but they both have different functions in music.
Choose which chord to play based on the function the chord has in the song.
