All chords More Db chordsDescription and theory
The Db9 is a dominant chord and equivalent to C sharp 9th. It consists of five notes, though depending on the instrument, some notes may be doubled or tripled. Since all the chord notes, except one, are absent among the open strings in standard tuning, there are no simple fingerings in open positions. Because of that, the chord is mostly played in closed positions or as a barre chord.
