Frequently asked questions
What is a chord finder?
A chord finder is a music tool that names the chord formed by a set of notes. Select the notes and it reports the chord symbol, quality, inversion, and common alternate spellings.
How does the chord finder detect inversions?
The lowest selected note is treated as the bass. If the bass is the third, fifth, or seventh of the chord, the result shows the inversion and a slash chord such as C/E.
Why do some notes have more than one chord name?
Some note sets are ambiguous. C E G A can be C6 or Am7/C, and diminished seventh chords repeat every minor third. Readings with the bass as the root are listed first.
Can I use sharps and flats?
Yes. Type notes such as F#, Bb, or E♭, and switch the display between automatic, sharp, and flat spellings. Enharmonic notes like C# and Db are treated as the same pitch.
What if my notes do not match a chord?
The finder names two-note intervals and suggests one-note fixes, such as removing an extra note or adding a missing seventh, so you can reach a common chord.
Are my notes uploaded anywhere?
No. Chord identification runs entirely in your browser, with no account, audio recording, or upload.
