The Reader's Guide to Music is designed to provide a useful single-volume guide to the ever-increasing number of English language book-length studies in music. Each entry consists of a bibliography of some 3-20 titles and an essay in which these titles are evaluated, by an expert in the field, in light of the history of writing and scholarship on the given topic. The more than 500 entries include not just writings on major composers in music history but also the genres in which they worked (from early chant to rock and roll) and topics important to the various disciplines of music scholarship (from aesthetics to gay/lesbian musicology).

The challenge, in twentieth-century music, to the normative status of triadic tonality is one of the most far-reaching and extreme revolutions that the history of music has known. In his classic work, Twelve-Tone Tonality, George Perle argues that the seemingly disparate styles of post-triadic music in fact share common structural elements. According to Perle, these elements collectively imply a new tonality as "natural" and coherent as the major-minor tonality that was the basis of a common musical language in the past. His book describes the foundational assumptions of this post-diatonic tonality and illustrates its compositional functions with numerous musical examples. The second edition of Twelve-Tone Tonality is enlarged by eleven new chapters. Some of these are "postscripts" to earlier chapters, clarifying, elucidating, and expanding upon concepts discussed in the original edition. Others discuss new developments in the theory and practice of twelve-tone tonality, including voice-leading implications of the system and dissonance treatment. Errors discovered in the original edition have been corrected. - Jacket flap.
