Play the notes, get the chord name
Click the notes you are holding on the keyboard and the chord names itself instantly, inversions and all. Hear it back to confirm, and find out what else that same set of notes could be called.
How to use it
From a mystery shape to a named chord in four steps.
Work out your notes
From a piano voicing, a guitar shape, or a MIDI clip, figure out which note names you are holding. On guitar, name the note each fretted string produces.
Click them on the keyboard
Tap each note. The lowest note you click is treated as the bass, which is how the tool tells a root-position chord from an inversion. Click again to deselect.
Read the name
The chord name appears instantly. If your bass note is not the root, you get a slash chord like C/E. The line underneath says what kind of chord it is and lists any other valid names for the same notes.
Hear it to confirm
Press Hear the chord to play your selection back. If it sounds like what you played, you have named it correctly.
Why naming chords is worth it
Communication. Telling another musician “it is a Gm7” transfers the idea in a second. “The shape with these four frets” does not survive the conversation.
Reusability. Once a mystery voicing has a name, you can transpose it, find its role in a key, and reuse it on purpose. It stops being a happy accident and becomes vocabulary.
Theory the painless way. Naming chords you already play is the easiest theory lesson there is, because the sound came first. The same notes can often carry more than one name, and which is correct depends on the bass note and the key you are in, which is exactly why the tool shows you the alternatives.

Questions, answered
Why does it say no exact match?
Either the notes form an extension or cluster beyond the library, such as 11ths, 13ths or altered chords, or there is a stray note in the selection. Remove the most doubtful note and try again. Most real voicings resolve to a named chord within one edit.
Do octaves matter?
No. The tool works on pitch classes, so the same note in different octaves counts once. The one thing that does matter is which note is lowest, since that bass note is what distinguishes a root-position chord from an inversion.
What is a slash chord like C/E?
It is a chord with a note other than the root in the bass. C major with E at the bottom is still C major, written C/E, called first inversion. The bass note changes how the chord behaves in a progression, so it is worth noting.
Why does one set of notes have two names?
Some note collections are genuinely ambiguous. C-E-G-A is both C6 and Am7. Which name is right depends on the key and the bass, so the tool shows both and lets you choose the one that fits your music.
Can I use this for guitar chords?
Yes. Work out the note each fretted string produces, click those notes here, and you get the proper name for the shape, including the half-remembered ones from tabs.
