D♭7 (D♭7)

Also called C♯7 (C♯7).

A dominant seventh chord: a major chord with an added minor seventh. It creates tension that pulls toward the next chord.

There’s no open shape: it’s played as a barre chord, starting at the 4th fret. It pulls toward F♯ major: you hear it right before the return home in songs in F♯ major, and all over the blues.

Notes:: D♭, F, A♭, C♭.
Formula:: 1, 3, 5, ♭7.
Difficulty:: Intermediate.
Strings played:: 5 (from the A string).
