Understanding Post-Tonal Music is a student-centered textbook that explores the compositional and musical processes of twentieth-century post-tonal music. Intended for undergraduate or general graduate courses on the theory and analysis of twentieth-century music, this book will increase the accessibility of post-tonal music by providing students with tools for understanding pitch organization, rhythm and meter, form, texture, and aesthetics. By presenting the music first and then deriving the theory, Understanding Post-Tonal Music leads students to greater understanding and appreciation of this challenging and important repertoire.

The updated second edition includes new "Explorations" features that guide students to engage with pieces through listening and a process of exploration, discovery, and discussion; a new chapter covering electronic, computer, and spectral musics; and additional coverage of music from the twenty-first century and recent trends. The text has been revised throughout to enhance clarity, both by streamlining the prose and by providing a visual format more accessible to the student.
