This illustrated book explores sound, starting with the basics - how does sound work? and what, exactly, is music? - and then describes how music and the ways we experience it have transformed over the years. It's a fascinating blend of history and science, broken into readable chunks, with graphic, colourful illustrations by Carl Wiens to enhance the text. This book has strong cross-curriculum links to physical science, engineering, technology, music and history. Alan Cross lives in Oakville, ON. Illustrator Carl Wiens lives in Belleville, ON.
