Fmaj9 on the ukulele is a major 9th chord made from F, A, C, E, G. Its first ukulele voicing is the open position: G string open; C string at fret 4 (middle finger); E string at fret 1 (index finger); A string open. Below you will find its notes and intervals, every usable voicing on the ukulele, the common mistakes players make with it and the keys and progressions where it belongs.
What notes are in the Fmaj9 chord?
The Fmaj9 chord is a major 9th chord, and its notes are fixed: F, A, C, E, G. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root F, so you can see the structure of Fmaj9 at a glance. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
| Note | Interval |
|---|---|
| F | Root |
| A | 3 |
| C | 5 |
| E | 7 |
| G | 9 |
The root is F, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Fmaj9 are 3, 5, 7, 9. Those intervals are the fingerprint of the major 9th quality — any chord with the same interval pattern, on any root, is the same kind of chord. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
Fmaj9 sounds lush, dreamy and wide open — the major 9th is one of the prettiest chords in popular music. That character comes straight from the intervals above, not from the instrument: the same notes on piano, guitar or ukulele carry the same colour, even though the voicing changes. On the ukulele, the open position voicing is the place to hear it in Fmaj9.
Comparing Fmaj9 with its closest relatives helps to fix it in your ear. In short, major 9th against dominant 9th: Fmaj9 keeps the major 7th E; the dominant 9th flattens it to D#. The major 9th sounds dreamy; the dominant 9th sounds bluesy. Practise the two chords back to back and listen to the one note that changes — that single note is the difference between the two chords. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
How to play Fmaj9 on ukulele
On the ukulele, Fmaj9 has 3 voicings in the data below, and each one uses the same notes — F, A, C, E, G — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
The open position puts Fmaj9 in open position: G string open; C string at fret 4 (middle finger); E string at fret 1 (index finger); A string open. The stretch is the challenge: the fretted notes span from fret 1 to fret 4, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Fmaj9 — F, A, C, E, G — sounds, with no buzz and no accidental open string.
Another way to play Fmaj9 is the barre chord, in around fret 5: G string open; C string at fret 5 (index finger); E string at fret 5 (index finger); A string at fret 7 (middle finger). It barres across strings 2 to 3 at fret 5 with the index finger. The barre is the hard part: the index finger must press every string from 2 to 3 evenly at fret 5, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in Fmaj9 — F, A, C, E, G — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want Fmaj9 in around fret 7: G string at fret 10 (middle finger); C string at fret 7 (index finger); E string open; A string open. The stretch is the challenge: the fretted notes span from fret 7 to fret 10, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Fmaj9 — F, A, C, E, G — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Fmaj9 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide Fmaj9 up the neck to any key without changing the shape. When you change chords, pick the voicing of Fmaj9 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Fmaj9 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
A short practice routine for Fmaj9 on the ukulele: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above F and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits.

Common mistakes
These are the mistakes that most often make Fmaj9 sound wrong on the ukulele, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Playing it too fast. Fmaj9 is a slow chord. At a fast tempo its colour gets lost; give each note time to sound. On the ukulele, the open position voicing is the place to hear it in Fmaj9.
Forgetting the 9th. Without G this is just a major 7th chord. The 9th is the note that makes it a 9th. On the ukulele, the open position voicing is the place to hear it in Fmaj9.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on Fmaj9 pulls the notes sharp and tires the hand. Use the lightest touch that gives a clean note, and keep your fingers close to the frets. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
Flattening the 7th. If the 7th is D# instead of E, the chord becomes a dominant 9th with a different function. Keep the 7th major. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
Where Fmaj9 is used
Fmaj9 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of C major, the key of F major, the key of A# major. a tonic chord in jazz and neo-soul, where the 9th adds width without tension. As a dominant-type chord it also points toward A# major, the key a perfect fourth above F, which is the tonic it most often resolves to. That is where Fmaj9 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, the open position voicing is the place to hear it in Fmaj9.
Because Fmaj9 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain F triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try Fmaj9 in a progression in any key and hear how it connects to the chords around it. On the ukulele, start with the first voicing above and listen for the notes F, A, C, E, G in Fmaj9.
The same chord on other instruments is covered in Fmaj9 on guitar, Fmaj9 on piano, Fmaj9 on bass, and the scales that fit over it are the F major scale and the F minor pentatonic scale. Learning Fmaj9 on the ukulele and then checking it on another instrument is one of the best ways to fix the notes — F, A, C, E, G — in your memory, because the notes stay the same while everything else changes.
Practising Fmaj9
A short worked example makes Fmaj9 concrete. Play the four-chord progression A# – F – Gm – D# in A# major, the key Fmaj9 most often resolves toward: A# – F – Gm – D#. Play each chord for one bar at a slow tempo, and listen to how Fmaj9 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on Fmaj9 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the ukulele, the open position voicing is the place to hear it in Fmaj9.
For a second exercise, play Fmaj9 and then the chord a fourth above F, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move Fmaj9 is built for when it acts as a dominant. Finish by playing Fmaj9 on its own, slowly, and naming each note out loud as you play it: F, A, C, E, G. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the ukulele, the open position of Fmaj9 puts those notes under your fingers in the order the fingering lists them.
