Hear the verse. Sing it back from memory.
Why this matters: holding an entire 8-bar verse in working memory and reproducing it in tune is the integration test for the whole 12-week curriculum. It combines pitch precision, phrase memory, tonal centering, and breath planning.
5 verses, 8–14 notes each. Listen once, wait 1.5s, then sing each note within ±50¢ for 0.8s. Land ≥85% of notes per verse; 4/5 passes the session.
