There has always been a close connection between physics and music. From the great days of ancient Greek science, ideas and speculations have passed backward and forward between natural philosophers (physicists) and musical theorists. Measured Tones: The Interplay of Physics and Music, Second Edition explores the story of that relationship in an entertaining and user-friendly way.

The book provides an easy-to-understand introduction to the physics involved in every stage of the music making process: from the very earliest experiments on vibrating strings and primitive sound makers to the latest concerns of digital sound recording, MP3 files, and information theory. At the same time, it examines the story of our developing concept of the universe we live in: from the ancient visions of a cosmos regulated by the music of the spheres to our current understanding of an expanding universe controlled by the laws of quantum mechanics and string theory. Running through all this is one recurring question - the so-called puzzle of consonance. Why do humans respond to music and musical sounds the way they do? It is the attempts by musicians and scientists through the ages to apply new knowledge to answer this question that gives this story its fascination.
