Gb 7 Guitar Chord | Play, Hear and Practice Interactively
The Gb7 chord, or Gb dominant seventh, is made of Gb, Bb, Db and Fb. It sounds like F#7, and the Fb is simply a theoretical way of writing E.
Eight voicings are listed and two use a barre; none has an open string, and the lowest is at the 2nd fret. In B major the same sound is V7, written F#7, so charts usually print that name. The Gb Mixolydian scale contains all four notes.

FAQ
Which notes spell Gb dominant seventh?
Gb, Bb, Db and Fb. That is a Gb major triad with a minor seventh on top. The Fb is the minor seventh and sounds the same as E.
Is Gb7 just another name for F#7?
Yes. F#7 uses F#, A#, C# and E, the same four pitches. Gb7 fits a flat-key chart, since F#7 would force sharps into the notation.
Why is the seventh of Gb7 written Fb and not E?
A seventh always uses the letter one step under the root's letter, G down to F. A minor seventh over Gb is a semitone lower than F, so it is Fb.
Where does the Gb7 chord sit as a V7?
Gb7 sounds like F#7, which is the V7 chord of B major. In that key the chord resolves to B, and its minor seventh E is the fourth degree.
How many voicings does Gb7 have?
There are 8 voicings, from fret 2 to fret 11. Two of them are barre voicings and none uses an open string.
