What chord is this?

Click the notes you're playing on the keyboard below. As soon as they match a chord in the library, it shows up with a link to its full page. Looking for scales instead? Try the scale finder.

The finder matches on pitch class only, not octave or which note is lowest, so C-E-G reads the same whether you click them low or high on the keyboard. Some results are symmetric chords, like diminished sevenths, that are genuinely the same keys under more than one name.
