Sound Garden
Parent plays different gentle sounds for baby — crinkling paper, tapping a glass, humming, shaking a jar of rice — and the agent coaches the parent to observe baby's reactions to different timbres, volumes, and rhythms. This activity explores early aesthetic sensitivity through auditory experience.
