Summary
This set of 9 video clips shows the developmental progression of children's knowledge about sound from infancy through five years of age. Watch as an infant works to confirm her discovery that that a toy horn can alter the pitch of her voice. Observe as a three-year-old boy teaches his two peers how to whistle. Around five years of age, children demonstrate an emerging understanding of the more formalized features of musical collaboration. Watch the children experiment with music notation, and invent gestures to indicate a change in pitch and signal fellow choir members about when to stop and start
