The D7 (D dominant 7) chord contains the notes D, F#, A and C. It is produced by taking the root (1), 3, 5 and b7 of the D Major scale. It is essentially a D chord, with an added flat 7.

The D7 is a popular open chord and used often in the key of D. Is is also commonly played with the root note on the 5th fret of the 5th string (second shape down, in the picture below).

D7 is short for D dominant 7. The dominant 7 chord is a significant chord, because it plays a very important function in any given key.

The dominant 7 chord functions as a chord that resolves to the first chord in a key. For example, the D dominant 7 chord resolves to the G Major chord (which is the first chord in the key of G)
