How chord recognition works
Chord identification works by looking at the intervals between the selected notes — the distances between them. C, E, and G have specific relationships (a major third and a perfect fifth from C), so they're recognized as C major.
The tool tries every possible root note and checks whether the selected notes match a known pattern. If they do, that’s the chord.
Some combinations of notes might be ambiguous — C, E, G could technically be C major or Am/C (A minor with C in the bass). The tool shows the most common interpretation. If it doesn't seem right, try removing one note or adding the bass note.
Questions
Why does it say 'No standard chord matched'?
Some combinations of notes don't correspond to a named chord. This is common with very large intervals, clusters of adjacent notes, or notes that happen to be in a key but don't form a standard chord pattern.
What chords can it recognize?
Major, minor, 7th, major 7th, minor 7th, half-diminished, diminished, augmented, sus2, sus4, 6th, minor 6th, add9, and diminished 7th. Most common chord types across all 12 root notes.
Does it matter which octave I click the notes in?
No — octave doesn't change what chord the notes form. C3 and C4 are both C. The tool identifies the chord from the note names regardless of octave.
How is this different from the Guitar Chord Identifier?
The Guitar Chord Identifier works from a fret shape — it looks up chords by their fingering pattern. This works from note names — it recognizes the chord from which notes you select. For piano players or anyone thinking in notes rather than shapes, this is the right tool.
