F#7 Guitar Chord
F# Dominant 7th · also written Gb7 · F#–A#–C#–E
F#7 is the F# dominant 7th chord: F#–A#–C#–E. Its sound is bluesy and unresolved — the dominant 7th wants to pull somewhere, which is why it powers blues turnarounds and V chords. It's also written as Gb7 — same notes, same shapes, different spelling.
F#7 is the V7 chord in the key of B, which is where its pull comes from — the ♭7 (E) rubs against the major 3rd and demands resolution. In a 12-bar blues in F#, every chord (I7, IV7, V7) gets this dominant treatment.
The most common way to play F#7 is the e7 shape at the 2nd fret (2 4 2 3 2 2, low E string to high E string). Below you'll find 6 ways to play it across the neck, from open position to barre and shell voicings, with the theory behind the chord and the progressions it lives in.
