Measured Tones : The Interplay of Physics and Music, Hardcover by Johnston, Ian, ISBN 1420093479, ISBN-13 9781420093476, Brand New, Free shipping in the US In this third edition of his work on the relationship of music and physics, Johnston (physics, University of Sidney, NSW Australia, emeritus) brings his study into the twenty-first century, including electronic music and computers as composers. The work is presented chronologically, starting with Pythagoras and his theories of mathematical intervals. "Interludes" between chapters explain the development and function or each type of instrument, including the human voice. During his voyage through history, Johnston pauses to discuss what the theories of Copernicus did to the music of the spheres, how the first phonographs worked, the development of musical notation and why computers only like ones and zeroes. Written in a humorous colloquial style with a great deal of erudition, this book will delight physicists and musicians as well as general readers curious about both.
