To play F#7sus4 on the ukulele, you need the notes F#, B, C#, E. Its first ukulele voicing is the movable voicing: G string at fret 4 (middle finger); C string at fret 4 (middle finger); E string at fret 2 (index finger); A string at fret 4 (ring finger). This guide covers the 7th suspended 4th 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#7sus4 chord?
The F#7sus4 chord is a 7th suspended 4th chord, and its notes are fixed: F#, B, C#, E. 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#7sus4 at a glance. On the ukulele, start with the first voicing above and listen for the notes F#, B, C#, E in F#7sus4.
| Note | Interval |
|---|---|
| F# | Root |
| B | 4 |
| C# | 5 |
| E | b7 |
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#7sus4 are 4, 5, b7. Those intervals are the fingerprint of the 7th suspended 4th 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.
F#7sus4 sounds spacious and dramatic, the sus4 colour on top of a dominant 7th. 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#7sus4 noticeably. On the ukulele, the movable voicing of F#7sus4 puts those notes under your fingers in the order the fingering lists them.
Comparing F#7sus4 with its closest relatives helps to fix it in your ear. In short, 7sus4 against sus4: F#7sus4 adds the flattened 7th E to the sus4 triad. The 7th makes it a dominant chord; the plain sus4 is neither major nor minor. 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, the movable voicing of F#7sus4 puts those notes under your fingers in the order the fingering lists them.
How to play F#7sus4 on ukulele
On the ukulele, F#7sus4 has 3 voicings in the data below, and each one uses the same notes — F#, B, C#, E — 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 movable voicing is the voicing to learn if you want F#7sus4 in around fret 2: G string at fret 4 (middle finger); C string at fret 4 (middle finger); E string at fret 2 (index finger); A string at fret 4 (ring finger). This voicing is comfortable because the fretted notes sit close together, from fret 2 to fret 4, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in F#7sus4 — F#, B, C#, E — sounds, with no buzz and no accidental open string.
The barre chord puts F#7sus4 in around fret 6: G string at fret 6 (index finger); C string at fret 6 (index finger); E string at fret 7 (middle finger); A string at fret 7 (middle finger). It barres across strings 1 to 2 at fret 6 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 2 evenly at fret 6, 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#7sus4 — F#, B, C#, E — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want F#7sus4 in around fret 4: G string at fret 4 (index finger); C string at fret 6 (ring finger); E string open; A string at fret 4 (middle finger). This voicing is comfortable because the fretted notes sit close together, from fret 4 to fret 6, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in F#7sus4 — F#, B, C#, E — sounds, with no buzz and no accidental open string.
Choosing between the voicings of F#7sus4 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#7sus4 up the neck to any key without changing the shape. When you change chords, pick the voicing of F#7sus4 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into F#7sus4 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, the movable voicing of F#7sus4 puts those notes under your fingers in the order the fingering lists them.
A short practice routine for F#7sus4 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#7sus4 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 the 3rd as well. If A# sounds with B, the chord clashes. The 3rd must be absent while the suspension lasts. On the ukulele, the movable voicing of F#7sus4 puts those notes under your fingers in the order the fingering lists them.
Forgetting the 7th. Without E this is just a sus4 triad. The 7th is what makes it a dominant chord. On the ukulele, the movable voicing of F#7sus4 puts those notes under your fingers in the order the fingering lists them.
Holding it too long. A suspended chord that never resolves sounds stuck. Use it as a delay, not a destination. On the ukulele, the movable voicing voicing is the place to hear it in F#7sus4.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on F#7sus4 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 movable voicing voicing is the place to hear it in F#7sus4.
Where F#7sus4 is used
F#7sus4 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 dominant chord that delays its resolution: play the sus4, then let it fall to the dominant 7th. 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#7sus4 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, the movable voicing voicing is the place to hear it in F#7sus4.
Because F#7sus4 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#7sus4 in a progression in any key and hear how it connects to the chords around it. On the ukulele, the movable voicing voicing is the place to hear it in F#7sus4.
The same chord on other instruments is covered in F#7sus4 on guitar, F#7sus4 on piano, F#7sus4 on bass, and the scales that fit over it are the F# major scale and the F# minor pentatonic scale. Learning F#7sus4 on the ukulele and then checking it on another instrument is one of the best ways to fix the notes — F#, B, C#, E — in your memory, because the notes stay the same while everything else changes.
Practising F#7sus4
A short worked example makes F#7sus4 concrete. Play the four-chord progression B – F# – G#m – E in B major, the key F#7sus4 most often resolves toward: B – F# – G#m – E. Play each chord for one bar at a slow tempo, and listen to how F#7sus4 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#7sus4 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#, B, C#, E in F#7sus4.
For a second exercise, play F#7sus4 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#7sus4 is built for when it acts as a dominant. Finish by playing F#7sus4 on its own, slowly, and naming each note out loud as you play it: F#, B, C#, E. 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 movable voicing voicing is the place to hear it in F#7sus4.
