Echo a P4 or P5 in either direction.
Why this matters: P4 (Here Comes the Bride) and P5 (Star Wars main theme) are the biggest landmark intervals in tonal music. Echoing them stabilizes long melodic jumps and locks in the dominant–tonic relationship.
10 prompts. We play two notes (random P4 or P5, up or down). Sing the second note within ±50¢ for 2.0s. Hit 8 of 10 to pass.
