The Ear Training Lab

You'll hear a randomly selected root position triad (major or minor). Your task is to identify the root note — the lowest note that names the chord.

Root notes range from C4 to B4, covering all 12 chromatic notes in that octave.

Click any key to audition it. Once selected, Next becomes Submit [note] — press to confirm. Use Replay to hear the triad again.

Use 🎵 Play Ref – C Major Triad to hear a C Major reference triad followed by the root note (C4) on its own.
