Check your understanding

Play beside the clef hears the whole example; press it again to stop. Click a note to hear it. On note-answer questions, that also selects or deselects it—even after Check—and changes your answer. On concept questions, choose an answer below the music.

Use Left/Right or Home/End to move between notes, then Enter or Space to hear it (and, on note-answer questions, select it). Check gives feedback; Next continues. A correct pentatonic answer leaves removed notes faint and silent in whole-example playback. Editing restores the original scale. Whole-example Play preserves your answer. Finish completes six questions without claiming a first-attempt score.
