HOW TO PLAY SONGS ON PIANO FROM CHORDS. three notes, one hand

Most songs you hear were never written out note for note. What a band passes round is a chord chart: the words with a chord name over each change, or a grid of bars with a chord in each. Guitarists read them without thinking. Piano players often don’t, because piano lessons start from sheet music, where every note is written down for you.

Playing from chords is a different skill, and a freeing one. A chord symbol tells you which notes belong together and nothing else. Which octave, which order, which rhythm: that is up to you. Once you can turn a symbol into a chord under your hands, any chart becomes something you can play, and a song you know can be accompanying a singer within the hour.

This guide starts where you have the chords and want to play them. If you need to work out the chords yourself, by listening, our guide to piano chords by ear does that part. Here the chords come from the recording, in time with it, so you can practise with the real song from the first minute.

You need the song, as a YouTube link or an audio file, and a keyboard. Work one section at a time, usually the chorus first, since it tends to repeat.

In the screenshot the demo song Coming Home is open in the Chord Lens Studio with Live chords set to Piano. The song is in B, but the Key is raised one semitone to C, so its four chords become C, F, G and Am, all on the white keys. Each chord is drawn on a keyboard with its notes named above it, C, E and G for the C at the playhead, and the chord sheet on the right shows the chords over the words.

A chord symbol names a root and a colour. The root is the letter: C, F♯, B♭. The colour is what comes after it, and most of the time there is nothing, which means major, or a small m, which means minor. Build either one from the root by counting keys, black ones included.

Major: the root, then four keys up, then three more. C major is C, E and G. Minor: the root, three keys up, then four more. A minor is A, C and E. Those three notes, root, third and fifth, are a triad, and a triad is all a pop song needs from you most of the time.

The extras build on the triad. A 7 adds the note two keys below the root’s octave: C7 is C, E, G and B♭. A maj7 adds the note a key under the octave: Cmaj7 adds B. A sus4 swaps the third for the note above it, sus2 for the note below it. A slash chord such as C/E means the chord C with E as the lowest note, which is a job for your left hand. Our guide to chord symbols goes through the rest.

You don’t have to count while the song plays. With Live chords on Piano, the Studio draws each chord on a keyboard with its notes lit and named, the root marked in red, so you can check a chord at a glance. If the chart is full of sevenths and sus chords you don’t know yet, switch on Simplify: every chord drops to its plain major or minor triad, and the song still sounds right under your hands.

The simplest way to split a chord between two hands works for almost every song. The left hand plays the root, alone or as an octave, low on the keyboard. The right hand plays the triad, in the middle. That one change, from a three-note chord to a bass note and a chord, is what makes a keyboard sound like a band.

Now the trick that makes it sound smooth: your right hand doesn’t have to play every chord from its root up. The same three notes in another order are still the same chord. These are called inversions, and they let your hand stay in one place while the chords change around it.

Take Coming Home in C. Play C as C, E and G. For F, don’t jump up to F, A and C: keep the C you already have and play C, F and A. For G, play B, D and G, and for Am play C, E and A. Your right hand barely moves through the whole chorus, while your left hand walks C, F, A, G under it. It sounds like a pianist, and it is easier than jumping.

The rule of thumb is to keep any note two chords share, and move the others to the nearest key. The Studio’s keyboards show each chord’s notes from the root up; the order you play them in is yours to choose. When the chart has a slash chord, play the note after the slash in your left hand instead of the root.

Holding each chord until the next one is a start, but a song needs movement. Here are four patterns, from easiest to fullest. Try each one over the same chorus.

Whole notes. Play the chord on the first beat of the bar and hold it. Good for slow songs and for learning the changes. Pulses. Play the right-hand chord on every beat, root held in the left. The most common pop accompaniment there is. Broken chords. Play the three notes one after another, low to high, round and round. It suits ballads. Left-hand root and fifth. Alternate the root and the fifth in your left hand on beats one and three while the right hand pulses. It gives the song a bass line.

Let the record tell you which one. Listen to what the drums and the original keys are doing. If the song pulses in eighth notes, so can you. Turn on the Studio’s metronome if you lose the count: it clicks on the song’s own beat, with beat one accented.

Want to hear just what the pianist on the record plays? The Piano Stem Splitter splits the song into six stems, so you can solo the piano and copy its pattern, or mute it and take its place.

Reading a chart while you play is its own skill. The trick is to look ahead: you should already know the next chord when the current one starts. A chart that scrolls with the song makes that much easier than paper.

The Studio’s chord sheet has three views. Lead puts the chords over the lyrics, line by line, the way most song charts are written; Lyrics shows the words alone; Grid shows the chords in bars, which is handy for intros and instrumental parts that have no words. The line being sung is lit and the sheet scrolls with it. Our Lyrics and Chords page shows the views side by side.

Notice where each chord sits on the word. A chord written over the second syllable lands there, not at the start of the line. Sing or hum along as you play and the timing falls into place.

If the song is too fast to follow, slow it down. The BPM stepper goes from half the song’s tempo to double, and the pitch stays where it is, so the chords on your keyboard still match. Loop a hard line until you can play through it, then raise the speed a few BPM at a time. Free keeps 3 saved loops per song.

Pianists don’t get a capo. A song in B, like Coming Home, has five sharps, and its chords B, E, F♯ and G♯m mean black keys in nearly every shape. You can learn it there, and in the end it’s worth doing, but you don’t have to start there.

Raise the Studio’s Key by one semitone and the recording itself moves up to C, with every chord re-spelled: C, F, G and Am. Now you are playing along with the real record, a semitone higher, in a key that is all white keys. The Key moves up to 12 semitones either way, so any song can land in a key you know. The Auto, Sharps and Flats buttons respell the names if a chart reads more easily one way.

This is also how you fit a singer. Move the key until the melody sits comfortably in their voice, then play the chords the Studio shows for that key. Our guide to transposing chords explains the counting behind it.

The chords, the piano diagrams and the lyrics a song already has are free on every plan, with no ads. The Studio asks you to sign in free with Google, and Free has a set number of new songs each month. Key and speed are free once you sign in. In Chrome, the Chord Lens extension shows the same chords and keyboards beside a YouTube video.

Chord Lens gives you the chords in time, not sheet music. The voicing, the rhythm and the left-hand part are yours to choose, which is exactly the skill this guide is about.
