Chord Identifier
Chord Identifier
Click the notes you are holding, optionally set the bass note, and get the chord name with alternatives, the inversion, and the major and minor keys that contain it.
Pick at least two notes. With three or more the match is exact; with partial matches you get the closest chords ranked. Set the bass note to name inversions and slash chords.
What chord is this?
You found a voicing on the keyboard or guitar that sounds right and need its name to write it down, tell the band, or build a progression around it. This identifier takes the notes you are holding and compares them against thirty chord qualities from every possible root, from plain triads to ninths, elevenths and thirteenths. Exact matches win; if the notes do not fit a textbook chord you get the closest candidates ranked, with an asterisk marking the approximate ones.
Inversions and slash chords
The same notes in a different order are the same chord with a different bass. Set the bass note and the identifier names the inversion or writes the slash chord, which is what a session player expects to see on a chart.
From chord to key
The keys list shows every major and minor key that contains all the selected notes, which is a fast way to decide where a progression can go next. Use it with the Scale and Chord Finder to see the other chords in those keys.
FAQ
How does the chord identifier work?
It reduces your notes to pitch classes and scores them against chord templates built on every root. Exact matches rank first, then the closest partial matches.
Why do I get two names for the same notes?
Some chords share notes: C6 and Am7 are the same four notes. The bass note usually decides which name is right.
Can it identify chords from audio?
Not directly. Use the Song Key Finder to get the key, then identify individual chords by ear or from the notes you play.
What is the difference between add9 and 9?
A 9 chord includes the seventh; add9 does not. Select the seventh note and the identifier will tell them apart.
