To play F#11 on the ukulele, you need the notes F#, A#, C#, E, G#, B. Its first ukulele voicing is the open position: G string at fret 4 (ring finger); C string at fret 4 (ring finger); E string at fret 2 (middle finger); A string at fret 1 (index finger). This guide covers the dominant 11th chord in full: what is in it, how to play it cleanly on the ukulele, where it fits musically and how to practise it.
What notes are in the F#11 chord?
The F#11 chord is a dominant 11th chord, and its notes are fixed: F#, A#, C#, E, G#, B. 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 F#11 at a glance. On the ukulele, start with the first voicing above and listen for the notes F#, A#, C#, E, G#, B in F#11.
| Note | Interval |
|---|---|
| F# | Root |
| A# | 3 |
| C# | 5 |
| E | b7 |
| G# | 9 |
| B | 11 |
The root is F#, the note the chord is named after and the note your ear hears as home. Above it, the intervals in F#11 are 3, 5, b7, 9, 11. Once you know the intervals, you can build F#11 from any root by counting the same semitone steps, which is how the chord works in every key. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
F#11 sounds complex but smooth, a dominant chord with an extra note that softens its edge. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of F#11 noticeably. On the ukulele, the open position of F#11 puts those notes under your fingers in the order the fingering lists them.
Comparing F#11 with its closest relatives helps to fix it in your ear. In short, 11th against 9th: F#11 adds the 11th B on top of the 9th G#. In practice the 3rd is often left out of the voicing, because the 11th clashes with it. Hearing the comparison matters more than reading it: play F#11, then play the chord it is compared with above, and let your ear find the note that changed. On the ukulele, the open position voicing is the place to hear it in F#11.
How to play F#11 on ukulele
On the ukulele, F#11 has 3 voicings in the data below, and each one uses the same notes — F#, A#, C#, E, G#, B — 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 F#11 in open position: G string at fret 4 (ring finger); C string at fret 4 (ring finger); E string at fret 2 (middle finger); A string at fret 1 (index finger). 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#11 — F#, A#, C#, E, G#, B — sounds, with no buzz and no accidental open string.
Another way to play F#11 is the barre chord, in around fret 2: G string at fret 3 (middle finger); C string at fret 4 (ring finger); E string at fret 2 (index finger); A string at fret 2 (index finger). It barres across strings 3 to 4 at fret 2 with the index finger. The barre is the hard part: the index finger must press every string from 3 to 4 evenly at fret 2, 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 F#11 — F#, A#, C#, E, G#, B — sounds, with no buzz and no accidental open string.
Another way to play F#11 is the movable voicing, in around fret 4: G string at fret 4 (index finger); C string at fret 6 (middle finger); E string at fret 6 (middle finger); A string at fret 7 (ring finger). The stretch is the challenge: the fretted notes span from fret 4 to fret 7, 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#11 — F#, A#, C#, E, G#, B — sounds, with no buzz and no accidental open string.
Choosing between the voicings of F#11 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#11 up the neck to any key without changing the shape. When you change chords, pick the voicing of F#11 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into F#11 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#, B in F#11.
A short practice routine for F#11 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#11 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.
Using it as a tonic. F#11 is a dominant chord. It wants to resolve to the tonic. On the ukulele, start with the first voicing above and listen for the notes F#, A#, C#, E, G#, B in F#11.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on F#11 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 of F#11 puts those notes under your fingers in the order the fingering lists them.
Playing the 3rd and 11th together. A# and B clash badly in the same octave. In an 11th chord the 3rd is usually omitted or placed far from the 11th. On the ukulele, the open position of F#11 puts those notes under your fingers in the order the fingering lists them.
Crowding six notes. Six notes are too many for most voicings. Drop the 5th and often the 3rd too, keeping root, 7th, 9th and 11th. On the ukulele, start with the first voicing above and listen for the notes F#, A#, C#, E, G#, B in F#11.
Where F#11 is used
F#11 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 B major. a V11 chord that resolves to the tonic with a suspended, open sound. 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#11 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, start with the first voicing above and listen for the notes F#, A#, C#, E, G#, B in F#11.
Because F#11 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#11 in a progression in any key and hear how it connects to the chords around it. On the ukulele, the open position of F#11 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in F#11 on guitar, F#11 on piano, F#11 on bass, and the scales that fit over it are the F# major scale and the F# minor pentatonic scale. Learning F#11 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#, B — in your memory, because the notes stay the same while everything else changes.
Practising F#11
A short worked example makes F#11 concrete. Play the four-chord progression B – F# – G#m – E in B major, the key F#11 most often resolves toward: B – F# – G#m – E. Play each chord for one bar at a slow tempo, and listen to how F#11 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#11 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the ukulele, start with the first voicing above and listen for the notes F#, A#, C#, E, G#, B in F#11.
For a second exercise, play F#11 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#11 is built for when it acts as a dominant. Finish by playing F#11 on its own, slowly, and naming each note out loud as you play it: F#, A#, C#, E, G#, B. 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 F#11 puts those notes under your fingers in the order the fingering lists them.
Frequently asked questions
What notes are in F#11?
F#11 contains F#, A#, C#, E, G#, B: root, major 3rd, perfect 5th, flattened 7th, 9th and 11th. In practice the 3rd is often omitted from the voicing, because it clashes with the 11th. On the ukulele, the voicings above put that note under your fingers.
Why is the 3rd often left out of F#11?
The 11th B is a semitone above the major 3rd A#, so the two notes clash in the same octave. Leaving the 3rd out keeps the chord open and lets the 11th colour it. On the ukulele, the voicings above put that note under your fingers.
Where is F#11 used?
F#11 is a dominant colour in jazz and fusion, used as a V11 that resolves to the tonic. It suits slow tempos and open voicings where its width can be heard. On the ukulele, the voicings above put that note under your fingers.
How do you play F#11 on the ukulele?
The first voicing is the open position: frets 4–4–2–1, fingers 3–3–2–1, on the ukulele. That voicing uses the notes F#, A#, C#, E, G#, B, and it is the one to learn first. The page above lists more voicings for F#11, so you can choose the shape nearest the chords around it.
Is F#11 hard to play on the ukulele?
It depends on the voicing. The first voicing of F#11 on the ukulele is the easiest starting point, and the movable voicings further up the neck are harder because they need a barre or a wider stretch. Practise the first voicing cleanly at a slow tempo before you try the others, and the harder shapes will come more easily.
