What notes are in the F#m9 chord?
The F#m9 chord is a minor 9th chord, and its notes are fixed: F#, A, C#, E, G#.

| Note | Interval |
|---|---|
| F# | Root |
| A | b3 |
| C# | 5 |
| E | b7 |
| G# | 9 |

That combination is what makes F#m9 sound the way it does: the intervals decide the colour, and the root decides the pitch. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
F#m9 sounds smooth, mellow and deep — the minor 9th is the most relaxed extended chord there is. Listen for that character when you play it — if F#m9 does not sound that way, one of the notes is probably wrong, and the table above is the place to check. On the ukulele, the open position voicing is the place to hear it in F#m9.
Comparing F#m9 with its closest relatives helps to fix it in your ear. In short, minor 9th against minor 7th: F#m9 adds the 9th G# to the minor 7th chord. The extra note widens the sound without changing the function. Play both chords slowly, one after the other, and notice which note moves. Naming that note out loud while you play is the fastest way to learn the difference. On the ukulele, the open position voicing is the place to hear it in F#m9.
How to play F#m9 on ukulele
On the ukulele, F#m9 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. There are 3 voicings listed for F#m9 on the ukulele; learn the first, then add the others as you need them. 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 is the voicing to learn if you want F#m9 in open position: G string at fret 1 (index finger); C string at fret 4 (ring finger); E string at fret 2 (middle 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 F#m9 — F#, A, C#, E, G# — sounds, with no buzz and no accidental open string.
The movable voicing puts F#m9 in around fret 8: G string at fret 11 (middle finger); C string at fret 8 (index finger); E string open; A string open. The stretch is the challenge: the fretted notes span from fret 8 to fret 11, 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 F#m9 — 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 F#m9 in around fret 9: G string at fret 11 (middle finger); C string at fret 9 (index finger); E string open; A string at fret 11 (ring finger). This voicing is comfortable because the fretted notes sit close together, from fret 9 to fret 11, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in F#m9 — F#, A, C#, E, G# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of F#m9 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 F#m9 up the neck to any key without changing the shape. When you change chords, pick the voicing of F#m9 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into F#m9 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 F#m9.
A short practice routine for F#m9 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 F#m9 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.
Raising the 7th. The 7th here is E, flattened. Play F and you get a minor-major 9th, a much tenser sound. On the ukulele, start with the first voicing above and listen for the notes F#, A, C#, E, G# in F#m9.
Crowding the voicing. Five notes need room. Drop the 5th (C#) first and keep the root, minor 3rd, 7th and 9th. On the ukulele, start with the first voicing above and listen for the notes F#, A, C#, E, G# in F#m9.
Losing the 9th. Without G# this is just a minor 7th chord. Make sure the note carrying the 9th rings clearly. On the ukulele, start with the first voicing above and listen for the notes F#, A, C#, E, G# in F#m9.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on F#m9 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, the open position voicing is the place to hear it in F#m9.
Where F#m9 is used
F#m9 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 D major, the key of E major, the key of A major. the ii chord in major keys and the i chord in minor keys, in richer form. As a dominant-type chord it also points toward B major, the key a perfect fourth above F#, which is the tonic it most often resolves to. That is where F#m9 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 F#m9.
Because F#m9 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 F#m9 in a progression in any key and hear how it connects to the chords around it. On the ukulele, the open position of F#m9 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in F#m9 on guitar, F#m9 on piano, F#m9 on bass, and the scales that fit over it are the F# major scale and the F# minor pentatonic scale. Learning F#m9 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 F#m9
A short worked example makes F#m9 concrete. Play the four-chord progression B – F# – G#m – E in B major, the key F#m9 most often resolves toward: B – F# – G#m – E. Play each chord for one bar at a slow tempo, and listen to how F#m9 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 F#m9 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the ukulele, the open position of F#m9 puts those notes under your fingers in the order the fingering lists them.
For a second exercise, play F#m9 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 F#m9 is built for when it acts as a dominant. Finish by playing F#m9 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 voicing is the place to hear it in F#m9.
