Chord Lookup
Identify any chord for guitar, piano or ukulele — see exactly where your fingers go and hear how the chord sounds, note by note.
What is Chord Lookup?
A visual chord dictionary for three instruments. Choose any of the 12 root notes and 30 chord types — from a simple C major to a Cmaj13 — and it shows you exactly how to play that chord: which keys to press on a piano, or which frets and fingers to use on guitar and ukulele, with real fingerings and several positions along the neck.
You can also hear every chord: press Play and each note sounds one at a time — lighting up its dot or key so you can follow along — then the full chord together. Made for music teachers and students, but useful to anyone learning songs, writing music, or checking a fingering on the spot.
Frequently asked questions
Which instruments are supported?
Guitar (standard EADGBE tuning), piano, and ukulele (standard GCEA tuning). Each has a dedicated lookup page with diagrams built for that instrument.
How many chords can I look up?
12 root notes × 30 chord types — around 360 chords per instrument, from basic triads (major, minor, sus, dim, aug) to 6ths, 7ths and extended chords up to 13ths. Guitar and ukulele chords include several positions along the neck.
Can I hear the chord?
Yes. Press "Play chord" (or the spacebar): each note sounds one at a time — its dot or key lights up as it plays — and then you hear the full chord together.
Can I use Do Re Mi (solfège) note names?
Yes. A toggle switches every label between English notation (C, D, E…) and Latin solfège (Do, Re, Mi…). Your choice applies to root notes, chord names and every diagram.
Do I need to read music?
No. Everything is shown visually — highlighted keys on a keyboard, or dots on a fretboard diagram with finger numbers. Note names are shown too, so you learn them as you go.
