Get It FreeSearch works in both directions. By name: type any chord symbol (Cm7, F♯dim, B♭maj7) and open its page with keyboard diagrams and fingerings. By notes: select the notes you are holding down, and the finder lists every chord they can spell — including inversions where another note takes the bass.
The same set of notes can have more than one valid name. C–E–G–A is C6, but it is also Am7 in first inversion; which name fits depends on the bass note and the harmony around it. When several chords match, the finder shows them all so you can pick the one that fits your context.
Every result links to a full chord page: notes in every inversion, keyboard diagram, fingerings for both hands, and the chord's aliases — so a chord you found by ear becomes one you can name, read and reuse.
Frequently asked questions
How do I find out what chord I'm playing?
Select the notes you are holding down in the finder above. It lists every chord those notes can spell, with links to each chord's chart and inversions.
Why does one set of notes match several chords?
Chords are named relative to a root. C–E–G–A reads as C6 if C is the root, or Am7 (first inversion) if A is. The musical context — usually the bass note — decides which name applies.
Is the chord finder free?
Yes. The finder and all chord pages are free in your browser. The Piano Companion app offers the same reverse lookup plus scales, progressions and offline use.
