Hello, World! Music teaches babies and toddlers all about musical instruments and the sounds they make—with colors, shapes, sizes, and super-simple facts! Hello, World! board books introduce first nonfiction concepts to babies and toddlers. Told in clear and easy terms with read-aloud sound words (“Plink! There are 88 keys on a piano, and they each make a different sound”) and featuring bright, cheerful illustrations, Hello, World! makes learning fun for young children.
