On the piano, the Gsus4 chord is the suspended 4th chord built from G, C, D. On piano it is played from the keys G, C, D, root position first, then in inversions. Keep this page open while you practise: it lists the notes, every practical voicing, the mistakes that make it sound wrong and the progressions where it does its best work.
What notes are in the Gsus4 chord?
The Gsus4 chord is a suspended 4th chord, and its notes are fixed: G, C, D. 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 G, so you can see the structure of Gsus4 at a glance. On the piano, Gsus4 is the keys G, C, D, and the inversions above move the same notes around.
| Note | Interval |
|---|---|
| G | Root |
| C | 4 |
| D | 5 |
The root is G, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Gsus4 are 4, 5. Once you know the intervals, you can build Gsus4 from any root by counting the same semitone steps, which is how the chord works in every key. On the piano, the notes appear in the order the fingering dictates, but the set of notes never changes.
Gsus4 sounds open but restless, the classic suspended sound that every listener recognises as unfinished business. Listen for that character when you play it — if Gsus4 does not sound that way, one of the notes is probably wrong, and the table above is the place to check. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
Comparing Gsus4 with its closest relatives helps to fix it in your ear. In short, sus4 against sus2: Gsus4 uses the 4th C where the sus2 uses the 2nd A. The sus4 is tenser and its resolution to the 3rd is more dramatic. Hearing the comparison matters more than reading it: play Gsus4, then play the chord it is compared with above, and let your ear find the note that changed. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
How to play Gsus4 on piano
On the piano, Gsus4 is played from the keys G, C, D. In root position the lowest note is G, the root, with the other notes stacked above it in the order G, C, D. Play it with the right hand first, then with the left hand an octave lower, so both hands know the shape of Gsus4 before you try it in a progression.
First inversion of Gsus4 puts C in the bass, with the notes in the order C, D, G. The chord is still Gsus4 — the notes have not changed, only their order — but the bass note changes how it connects to the chord before and after it. Use this inversion when the bass line wants to step to C rather than jump to G, and practise moving from root position to this inversion without lifting your hand off the keys more than you must.
Second inversion of Gsus4 puts D in the bass, with the notes in the order D, G, C. The chord is still Gsus4 — the notes have not changed, only their order — but the bass note changes how it connects to the chord before and after it. Use this inversion when the bass line wants to step to D rather than jump to G, and practise moving from root position to this inversion without lifting your hand off the keys more than you must.
For fingering, a good starting point for Gsus4 in root position in the right hand is thumb on G, then one finger per note in order, with the little finger on the top note D. For the left hand, mirror it: little finger on the low G and thumb on the top note. When a note is a black key — none of the notes in this chord are black keys — let your longer fingers take it, since they reach the black keys more easily. Practise Gsus4 in root position and first inversion, hands separately, then together, at a slow tempo, and use the Piano Chord Finder to check the voicing on the keyboard.
Common mistakes
These are the mistakes that most often make Gsus4 sound wrong on the piano, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Playing every inversion with the same hand shape. Each inversion of Gsus4 needs its own hand shape, because the notes sit under different fingers. If you force the root-position fingering onto an inversion, the hand cramps and notes get missed. Learn the fingering for each inversion of Gsus4 separately, hands apart, before you join them. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
Never resolving the 4th. The 4th C wants to fall to B. If you sit on the sus4 forever the chord sounds stuck. Practise the sus4-to-major move until the resolution feels natural. On the piano, Gsus4 is the keys G, C, D, and the inversions above move the same notes around.
Resolving to the wrong 3rd. The sus4 resolves to the major 3rd B, not the minor 3rd. Resolve to A# and you have changed key, not resolved. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
Playing the 3rd as well. If B sounds together with C the chord clashes badly. The 3rd must be absent while the 4th is present. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
Where Gsus4 is used
Gsus4 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 D major, the key of G major. a way to delay a chord: play the sus4, hold it, then let it fall to the triad. As a dominant-type chord it also points toward C major, the key a perfect fourth above G, which is the tonic it most often resolves to. That is where Gsus4 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the piano, play the keys G, C, D slowly and listen for each note of Gsus4 in turn.
Because Gsus4 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 G 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 Gsus4 in a progression in any key and hear how it connects to the chords around it. On the piano, Gsus4 is the keys G, C, D, and the inversions above move the same notes around.
The same chord on other instruments is covered in Gsus4 on guitar, Gsus4 on ukulele, Gsus4 on bass, and the scales that fit over it are the G major scale and the G minor pentatonic scale. Learning Gsus4 on the piano and then checking it on another instrument is one of the best ways to fix the notes — G, C, D — in your memory, because the notes stay the same while everything else changes.
Practising Gsus4
A short worked example makes Gsus4 concrete. Play the four-chord progression C – G – Am – F in C major, the key Gsus4 most often resolves toward: C – G – Am – F. Play each chord for one bar at a slow tempo, and listen to how Gsus4 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 Gsus4 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the piano, Gsus4 is the keys G, C, D, and the inversions above move the same notes around.
For a second exercise, play Gsus4 and then the chord a fourth above G, 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 Gsus4 is built for when it acts as a dominant. Finish by playing Gsus4 on its own, slowly, and naming each note out loud as you play it: G, C, D. 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 piano, the root-position keys G, C, D show Gsus4 most clearly.
Frequently asked questions
How do you resolve Gsus4?
Let the 4th C fall by a semitone to the major 3rd B. That one-step move, sus4 to major, is the classic resolution and the sound every listener expects. On the piano, the keys above put that note under your fingers.
Is Gsus4 major or minor?
Neither, while it is suspended: it has no 3rd. It usually resolves to the major triad, which is why it is most often heard as a delayed major chord. On the piano, the keys above put that note under your fingers.
How do you play Gsus4 on the piano?
In root position, play the keys G, C, D, with G as the lowest note. That is the basic shape of Gsus4 on the piano. The inversions above put a different note in the bass, and the Chord Inverter shows every inversion of Gsus4 on the keyboard.
What is the first inversion of Gsus4?
The first inversion of Gsus4 puts C in the bass, with the notes in the order C, D, G. The chord is still Gsus4 — only the bass note has changed — and it is the inversion to use when the bass line steps to C.
Which fingers do you use for Gsus4 on piano?
In the right hand, start with the thumb on G and one finger per note in order, ending with the little finger on D. In the left hand, mirror it with the little finger on the low G. Longer fingers take the black keys, so check which notes of Gsus4 are black keys before you settle on a fingering.
