This educational toy introduces children to sound composition by demonstrating how individual instrument sounds combine to form eight Mozart compositions. It features authentic sound samples from five classical instruments: harp, flute, French horn, piano, and violin. The orchestra function allows all instruments to play simultaneously, while synchronized LED lights pulse in time with the musical tempo. Designed for aspiring young musicians, the toy has soft, rounded edges for safe handling by small children. The unit operates on three AA batteries (included for trial use; Polaroid AA batteries recommended for optimal performance). Suitable for children of various ages.
