How it names chords

The detector compares your selected pitch classes against common chord formulas such as major, minor, 7, maj7, m7, sus, dim, aug, add9, 9, 11, and 13. It also shows slash notation when the bass note differs from the root.

Best results

The app works best when the root note is included. Some guitar voicings are ambiguous, especially when they omit the root or fifth, so alternatives are shown when multiple names fit.
