Guitar Chord Identifier
Enter the frets you are holding to find matching chord names, including inversions.
Matching chord names
C
Played notes: C3 · E3 · G3 · C4 · E4
Enter only the strings you actually play
Set each string to its fret number, Open, or Mute. The controls run from the lowest string to the highest. Select the instrument tuning before entering the shape because the open pitches determine every fretted note.
For a first example, enter x–3–2–0–1–0 in standard tuning. The notes are C3, E3, G3, C4, and E4, so the result is C major. Muting is different from an open string: a muted string contributes no pitch.
Why several names can be correct
The tool compares the distinct notes against its chord dictionary. Repeated octaves do not add a new chord tone. A slash after a chord name identifies a bass note other than the root, as in C/E.
Some collections of notes allow several roots or interpretations. The result lists exact matches and gives priority to a root in the bass. Musical context can still favor another name.
What no exact match means
The current dictionary recognizes major and minor triads, common sevenths, suspended chords, diminished and augmented triads, and power chords. Extensions such as ninths or chords with omitted tones may fall outside that set.
An unmatched result does not mean the shape is wrong. Check for a ringing open string, verify the tuning, and read the listed pitches. This identifier takes fret positions; it does not transcribe microphone recordings.
