To play a piano chord, press three or more keys at the same time, with the right hand using fingers 1, 3, and 5 for a triad, and the left hand using 5, 3, and 1. A C major chord is C, E, and G, played together, and the notes are the root, the major 3rd, and the perfect 5th.

To play a piano chord, press three or more keys at the same time, with the right hand using fingers 1, 3, and 5 for a triad, and the left hand using 5, 3, and 1. A C major chord is C, E, and G, played together, and the notes are the root, the major 3rd, and the perfect 5th, and the chord is the harmony, and the harmony is played with the hands together, pressing the keys down, and holding them, so the notes ring together, and the chord is heard as one sound. The piano is the easiest instrument to see a chord on, because the keys are laid out in a line, and the notes are visible, and the chord is the keys, pressed together, and the player can see the notes, and feel them, and hear them, all at once. A triad is the basic chord, with three notes, the root, the 3rd, and the 5th, and the triad is played with three fingers, 1, 3, and 5 in the right hand, and 5, 3, and 1 in the left hand, and the fingers are the thumb, the middle finger, and the pinky, and the hand is curved, with the fingers on the keys. The C major piano chord and the G major piano chord are the chords most players first play, and the metronome keeps the beat steady.
How piano chords work
A piano chord works because the keys are pressed down together, and the hammers strike the strings, and the strings vibrate, and the notes ring together, as one chord. The chord is the notes, played at the same time, and the notes are the root, the 3rd, and the 5th, and the interval from the root to the 3rd determines whether the chord is major or minor: a major 3rd, four semitones, makes a major chord, and a minor 3rd, three semitones, makes a minor chord, and the 5th is a perfect 5th, seven semitones, in both, and the chord is major or minor, by the 3rd. The right hand plays the chord with fingers 1, 3, and 5, the thumb, the middle finger, and the pinky, and the hand is curved, with the fingers on the keys, and the wrist is level, not bent, and the arm is relaxed, not tense, because the tension makes the playing worse, and the relaxation makes the chord ring. The left hand plays the chord with fingers 5, 3, and 1, the pinky, the middle finger, and the thumb, and the hand is a mirror of the right hand, with the same curve, and the same relaxation. The D major piano chord and the A major piano chord are the chords the playing is built on.
Worked example — playing a C major chord. Put your right hand on the piano, with the thumb on C, middle C, C4, 261.63 Hz, the middle finger on E, E4, 329.63 Hz, and the pinky on G, G4, 392 Hz, and press the three keys down together, at the same time, and hold them, and the notes ring together, C, E, G, which are the root, the major 3rd, and the perfect 5th of C major, and the chord is C major, played with fingers 1, 3, and 5. Now put your left hand on the piano, with the pinky on C, C3, 130.81 Hz, the middle finger on E, E3, 164.81 Hz, and the thumb on G, G3, 196 Hz, and press the three keys down together, and the notes ring together, C, E, G, and the chord is C major, played with fingers 5, 3, and 1, and the two hands together make the chord fuller. The key of C major lists the chords the playing is built on.
How to practise playing piano chords
Practise playing piano chords by playing one chord at a time, with each hand, until the fingers are in the right place, and the chord rings cleanly, and then play the chords together, with both hands.
- Play a C major chord with the right hand, fingers 1, 3, and 5, on C, E, and G, pressing the keys down together, and listening for the notes to ring together.
- Play a C major chord with the left hand, fingers 5, 3, and 1, on C, E, and G, pressing the keys down together, and listening for the notes to ring together.
- Play the I–V–vi–IV progression in C major with the right hand, and then with the left hand, changing chords smoothly, and listening for the harmony to change.
- Practise with the metronome at 60 beats per minute, and increase the tempo by 5 beats per minute when the chords are clean at the current tempo.
- Use the piano note finder to check the notes of any chord, and name each note as you play it, so the notes are learned with the fingers.
Common mistakes
- Playing the notes one at a time, not together — A chord is the notes played together, at the same time, and playing them one at a time makes an arpeggio, not a chord, and the harmony will not be heard. Press the keys down together, at the same time, and hold them, so the notes ring together.
- Using flat fingers — Flat fingers will hit neighbouring keys, and play wrong notes, and the chord will be muddy, because the fingers are not curved, and they touch the keys they should not touch. Curve your fingers, with the fingertips on the keys, and the chord will be clean.
- Tensing the arm — A tense arm will make the chord hard, and the playing will be stiff, and the hand will tire, and the chords will be slow. Relax the arm, let the weight fall into the keys, and the chord will ring, with less effort.
Quick reference
This table shows the four basic triads in C major, with the right-hand fingers and the notes for each one, so you can see the chords side by side and practise them one at a time. The fingers are 1, 3, and 5, the thumb, the middle finger, and the pinky, and the notes are the root, the 3rd, and the 5th.
| Chord | Right-hand fingers | Notes |
|---|---|---|
| C major | 1 – 3 – 5 | C – E – G |
| D minor | 1 – 3 – 5 | D – F – A |
| E minor | 1 – 3 – 5 | E – G – B |
| F major | 1 – 3 – 5 | F – A – C |
| G major | 1 – 3 – 5 | G – B – D |
| A minor | 1 – 3 – 5 | A – C – E |
Use the table to practise the triads in C major: play each chord with the right hand, fingers 1, 3, and 5, and then with the left hand, fingers 5, 3, and 1, and listen for the notes to ring together. When you can play all six chords, you can play the key of C major, and the harmony is yours.
Frequently asked questions
How do I play piano chords?
Press three or more keys at the same time, with the right hand using fingers 1, 3, and 5 for a triad, and the left hand using 5, 3, and 1. A C major chord is C, E, and G, played together, and the notes are the root, the major 3rd, and the perfect 5th.
What fingers do I use for piano chords?
The right hand uses 1, 3, and 5, the thumb, the middle finger, and the pinky, and the left hand uses 5, 3, and 1, the pinky, the middle finger, and the thumb, and the hand is curved, with the fingertips on the keys.
What is a triad on piano?
A triad is a chord with three notes, the root, the 3rd, and the 5th, and a major triad has a major 3rd, four semitones, and a minor triad has a minor 3rd, three semitones, and the 5th is a perfect 5th, seven semitones, in both.
How do I change chords smoothly on piano?
Move the fingers as a group, from one chord to the next, keeping the hand curved, and the wrist level, and the arm relaxed, and practise the change slowly, until it is smooth, and then increase the speed, with the metronome.
Should I play chords with one hand or two?
Start with one hand, until the chords are clean, and then play with two hands, the left hand playing the root and the 5th, and the right hand playing the full chord, so the sound is fuller, and the harmony is complete.
