About the F#add9 Chord on Guitar
The F#add9 chord is built from four notes: F# (the root), A# (the major 3rd), C# (the perfect 5th), and G# (the 9th). It is the F# major triad with an added 9th and no 7th — bright and open, with a shimmering colour over a firmly major base. Because none of its notes match open guitar strings, every voicing is fretted and moveable. F#add9 is enharmonically identical to G♭add9 — same pitch, same shapes, different spelling depending on the key. This page covers three voicings: a compact no-barre top-string form, a full E-shape barre, and a moveable A-shape barre. Every diagram is interactive and playable with acoustic guitar sound.
