Sing 1-3-5-3-1, two keys deep.

Why this matters: hearing the tonic triad in any key and reproducing it from the body unlocks every harmony exercise downstream. We rotate I and V keys so you build transposition, not just memorize one shape.

4 arpeggio trials, alternating tonic and dominant keys. Each note ±50¢. Pass when 4/5 notes hit per trial.
