Fadd9 is F major with one extra note on top: G, the ninth. The chord keeps everything that makes F sound like F, and the G opens it up, a little brighter, a little more spacious. On guitar it also has a practical side: its easiest shape grows straight out of the small F you may already know, with one more finger and no barre.
Fadd9 chord: notes and shapes at a glance
- Name: F add nine
- Symbol: Fadd9
- Notes: F, A, C, G
Each shape below is written from the thickest string to the thinnest: a
number is the fret, 0 an open string, x a string you
do not play. New to this? See how to read chord diagrams.
| Shape | Frets, low E to high E | Notes, low to high | What it is for |
|---|---|---|---|
| Fadd9, four strings | xx3213 | F A C G | No barre, no thumb: the small F shape with the fourth finger adding G on the high E. |
| Fadd9, thumb bass | 1x3213 | F F A C G | The same shape with the thumb on F at the first fret of the low E. The fifth string stays muted. |
| Fadd9, fifth string root | x 8 7 5 8 x | F A C G | A wide, piano-like voicing up the neck: root on the fifth string, G on top. A stretch from fret 5 to fret 8. |
Read each diagram from the thickest string on the left to the thinnest on the right. A cross means the string is not played, a circle means it rings open.
Fadd9 on the neck: every F, A, C, G
Standard tuning, frets 0 to 12. The highlighted notes are the notes of Fadd9: any shape you build from them, anywhere on the neck, is still Fadd9.
How to play Fadd9, step by step
1. Start from the small F
Third finger on the fourth string at fret 3 (F), second finger on the third string at fret 2 (A), first finger on the second string at fret 1 (C). That is the core of F.
2. Add the ninth: xx3213
Put the fourth finger on the high E at fret 3. That note is G. Strum from the fourth string down. You now have all four notes: F, A, C, G.
3. Add the bass: 1x3213
Hook the thumb over the neck onto the low E at fret 1. It gives the chord an F in the bass. The fifth string is not played: let the thumb touch it lightly, or simply start the strum below it.
Fadd9, Fsus2 and F9: three different chords
These three names get mixed up all the time. One note decides each of them.
| Chord | Notes | What it means |
|---|---|---|
| Fadd9 | F, A, C, G | Full F major, plus the ninth. Still major, still at rest. |
| Fsus2 | F, G, C | The third (A) is gone, replaced by G. Open, undecided. |
| F9 | F, A, C, Eb, G | Adds the flat seventh too: a dominant chord that pulls to Bb. |
The quick test on the fretboard: in xx3213, lift the second finger and the open G string rings in place of A. That is no longer Fadd9.
Progressions with Fadd9
Fadd9 works best where F already is: as the IV chord in C, or as home in F. Practice these slowly, four beats per chord, and listen for the G appearing and disappearing.
| Progression | Shapes | What to listen for |
|---|---|---|
| F, Fadd9, F | 1x3211, 1x3213, 1x3211 | Only the fourth finger moves. The harmony stays put, the color breathes. |
| F, Fadd9, C, G | xx3211, xx3213, x32010,
320003 | The add9 as a passing color inside a common loop. |
| C, Fadd9, Am, G | x32010, xx3213, x02210,
320003 | Fadd9 as the IV chord of C, in place of a plain F. |
| F, Fadd9, Fsus4, F | 1x3211, 1x3213, 1x3311,
1x3211 | Three colors on one bass note. The Fsus4 is the one that wants to come home. |
Common mistakes
- Losing the A. The chord becomes Fsus2 without your noticing. Check the third string on its own.
- Letting the fifth string ring. The open A is in the chord, but in the bass it blurs the F root. Start the strum on the fourth string or with the thumb.
- Using it everywhere. An add9 on every F stops sounding like a color. Keep it for an intro, a held chord, an arpeggio.
If the plain chord is still a struggle, the F chord page builds it from three strings to the full barre, and Fmaj7 is the other easy way to color F.
