Chord Lookup
Identify any chord for guitar, piano or ukulele. Look a chord up by name to see where your fingers go — or enter the notes you’re playing and we’ll name the chord.
What is Chord Lookup?
A visual chord dictionary for three instruments, working in both directions. Type a chord name, or 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.
On guitar and ukulele you can set a capo and everything is recalculated — the shape you actually play, the fret numbers counted from the capo, and the pitches you hear — while Lower and Higher slide capo and shape up or down the neck together.
It works in reverse too: enter the notes you’re playing and we name the chord — clicking the frets or keys, or playing them straight from a MIDI keyboard on the piano page. Order and octave never matter, so Do–Mi–Sol, Mi–Sol–Do and Sol–Do–Mi are all simply C major.
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.
Whether you call it a chord finder, a chord calculator, or a chord analyzer — it’s the same tool, and it works both ways: look up a chord by name, or enter notes and let it identify the chord for you.
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 just type the chord name?
Yes. The search box takes almost any spelling — Cmaj7, CM7, C-7, F#m7b5, Bb sus4, even solfège like sol7 or do menor. Press / to jump straight to it, use ↑↓ to pick a suggestion and ↵ to load it.
Can I go the other way and name a chord I’m playing?
Yes — that’s the “Notes → name” mode on every instrument page. Click the keys or the frets you’re holding (or play them on a MIDI keyboard on the piano page) and we name the chord, with alternatives when the same notes have more than one valid name.
Does the order or octave of the notes matter?
No. The name comes from the set of notes, so Do–Mi–Sol, Mi–Sol–Do and Sol–Do–Mi are all simply C major.
Can I use a capo?
On guitar and ukulele, yes. Set a capo position and everything is recalculated: the shape you actually play, the fret numbers counted from the capo, and the pitches you hear. Lower and Higher slide capo and shape together.
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…), and your choice is remembered as you move between instruments. Typing a chord in solfège switches it automatically.
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.
