The books in this collection offer a fun, accessible, and educational introduction to music by focusing on a particular theme. The first three are about birds, fantasy creatures, and water. This fourth book is about animals and the various compositions they've inspired through the ages. These pages are populated with flies, wasps, frogs, spiders, crickets, ants, and butterflies as imagined and recreated musically by composers like Rimsky-Kórsakov, Haendel, Bartók, Ravel, Telemann, Haydn, Prokófiev, and Revueltas.
