The Chicco Baby Piano Do Re Mi has two play modes which you select by turning the pages of the booklet: Musical Notes: the baby presses the keys that light up and discovers the sound of individual notes; Melodies: each key on the piano has different melodies: Classical, Jazz, Pop, Rock and Caribbean. The keys flash to the rhythm of the music and baby learns to distinguish between different musical styles. Moving the musical note, depending on mode selected, you can re-create the sound effect of a musical scale or add to melodies a fun jingle.
