How to play

Start the game and listen to the notes played together. Choose Major or Minor. Replay with R if you need another listen, then continue through ten rounds.

Scoring and methodology

A major triad uses root, major third and perfect fifth; a minor triad lowers the third by one semitone. Each correct classification earns one point, with a separate major/minor personal best.

What this test can tell you

This exercise covers major and minor triads. It does not assess inversions, seventh chords, chord progressions or general musical ability.
