How chord detection works

Your notes are matched against the chord table this site is built on, so every name it gives back can also be spelled, given a degree formula, played on the keyboard and drawn on the neck. It only names chords out of the notes you actually chose — no extra note appears in the answer.

Frequently asked questions

What does the chord finder do?
Given any group of notes, it finds the chord names that match. It's the reverse of looking up a chord in a chord library.
Does it detect inversions and slash chords?
Yes. The lowest selected note is treated as the bass; if it differs from the chord root, you'll see slash-chord names like C/G.
Why do I get multiple chord names for the same notes?
The same set of notes can spell different chords depending on which note is the root. We list every reasonable interpretation.
Which key are these notes in?
Open the Likely key tab under the tool: every key that contains your notes is scored and spelled with its own key signature, so a flat key is named B♭ minor rather than A♯ minor.
