The Db7 (D flat dominant 7) chord contains the notes Db, F, Ab and Cb. It is produced by taking the root (1), 3, 5 and b7 of the Db Major scale. It is essentially an Db chord, with an added flat 7.

Db7 is most commonly played with the root note on the 4th fret of the 5th string.

Db7 is short for Db 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 flat dominant 7 chord resolves to the Gb Major chord (which is the first chord in the key of Gb)
