Chord Identifier
Select notes to find likely chord names, formulas, and alternate interpretations.
C is being treated as the bass/root clue. Also called C dominant seventh. The selected notes match the formula 1 3 5 b7.
The b7 is what makes this a dominant seventh chord.
Inversions depend on which note is in the bass, so the same note set can still have several useful labels.
All selected notes fit the chord, and the essential chord tones are present.
Chord names can depend on bass note, key context, and how the notes function in the song.
About this tool
Chord Identifier helps you name a group of notes. If you find an interesting shape on guitar, stack notes on a keyboard, or see a cluster in an arrangement, this tool gives you likely chord names.
Chord names are contextual. The bass note, key, spelling, and musical function can change the best label, so the tool shows likely matches rather than pretending every note set has one absolute name.
What the results mean
The main result is the strongest match for the selected notes. Formula shows how those notes relate to the root, while alternate names show inversions or other useful spellings.
When to use it
Use it when labeling a voicing, checking an unfamiliar chord, arranging harmony, or understanding a sound you found by ear.
