F#sus4 Guitar Chord
F# Sus4 · also written Gbsus4 · F#–B–C#
F#sus4 is the F# sus4 chord: F#–B–C#. Its sound is tense and suspended — the 4th leans hard on the 3rd it displaced, begging to resolve. It's also written as Gbsus4 — same notes, same shapes, different spelling.
Suspended chords are about motion: F#sus4 usually resolves to plain F# or F#m, and strumming between them is a songwriting trick you've heard in everything from The Who to Tom Petty. Because there's no 3rd, F#sus4 works over both major and minor contexts in the key of F#.
The most common way to play F#sus4 is the barre shape at the 2nd fret (2 4 4 4 2 2, low E string to high E string). Below you'll find 8 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.
