Koko Plays a Flute Duet with her Doll [2008 KokoArc Video]
Koko was very creative and frequently initiated pretend play. She would make her dolls sign, and seen here she is having one of her favorite dolls, a WaterBaby, “play” the recorder (a type of flute). Koko was also capable of modulating her breath which enabled her to play the recorder with her doll (at 2 different volumes and pitches).
