FAQ

What notes are in Db dominant seventh?

Db7 is Db, F, Ab and Cb. The Cb is the minor seventh, written as a C flat because the letters have to run D, F, A, C.

Is Db7 the same as C#7?

Yes. C#7 is spelled C#, E#, G# and B, and it sounds exactly like Db7 with Db, F, Ab and Cb. The two names simply belong to different keys.

Why does Db7 include Cb instead of B?

A seventh takes its letter from the root: D up to C. A minor seventh over Db is a semitone lower than C, so it is written Cb, and it sounds like B.

Which scale suits the Db7 chord?

Db Mixolydian is Db, Eb, F, Gb, Ab, Bb and Cb. All four chord notes are in it, and the Cb is what makes the scale dominant rather than major.

How many voicings does Db7 have on the fretboard?

There are 12 voicings, spread from fret 2 to fret 13. Four are barre voicings, and none uses an open string.
