Piano Chord Lookup
Identify piano chords from pressed keys — every note of the chord highlighted on the keyboard, with its name.
About the piano chord lookup
A visual dictionary of piano chords. Pick any of the 12 root notes and 30 chord types — from a simple C major triad to a Cmaj13 — and the keys you need to press light up on a three-octave keyboard, each labelled with its note name. The root note is shown in a solid color so you always know where the chord is built from.
Press Play to hear the chord note by note — each key lights up as it sounds — and then all notes together. Switch between English note names (C, D, E) and solfège (Do, Re, Mi) with one click.
Piano chord FAQs
How do I read the keyboard diagram?
Every highlighted key is part of the chord, labelled with its note name. The root note — the note the chord is named after — is shown in a solid, darker color; the other chord tones are lighter.
Which hand should I play the chord with?
Either. The diagram shows the notes, not a hand. A common starting point: play the chord with your right hand and the root note an octave lower with your left.
Can I play the chord in a different octave?
Yes — the pattern of keys is identical in every octave. Play the same shape higher for a brighter sound or lower for a fuller one.
What about inversions?
The diagram shows the chord in root position (root at the bottom). To play an inversion, move the lowest highlighted note up an octave — the chord keeps its name and quality.
What’s the difference between "C D E" and "Do Re Mi"?
Two naming systems for the same notes: English notation (C, D, E…) and Latin solfège (Do, Re, Mi…), common in Spain and Latin America. Use the toggle above the keyboard to switch — every label updates.
