A Geometry of Music

Description

In this groundbreaking book, Tymoczko uses contemporary geometry to provide a new framework for thinking about music, one that emphasizes the commonalities among styles from Medieval polyphony to contemporary jazz.

• User-friendly introduction to a radically new approach to music theory and tonality
• New interpretation of the history of Western music reveals surprising commonalities among different musical styles
• Hundreds of original diagrams and illustrations

About the Author(s)

Dmitri Tymoczko, Associate Professor, Princeton University

Dmitri Tymoczko is a composer and music theorist who teaches at Princeton University. His 2006 article "The Geometry of Musical Chords" was the first music theory article published in the 127-year history of Science magazine, and was widely covered in the popular press. His music has been performed by ensembles throughout the country, and he has received a Rhodes scholarship, a Guggenheim fellowship, and numerous other awards.
