Paul Rand and his wife, Ann, wrote this book for their daughter, Catherine, to explain the interplay of sound and color. Paul's distinctive papercut illustrations of bold shapes and bursts of color beautifully complement Ann's rhythmic text, encouraging children to listen and repeat noises they hear every day: the "blop" of a raindrop, the "wham!" of a shutting door, the whisper of the wind in the trees, and the "crunch crunch" of buttered toast.
