A wide variety of essays by colleagues and former students reflect Professor Strunk's particular role as music historian, teacher, and a pre-eminent musicologist. Donald Grout provides the introduction and outlines the problems confronting musicology today. Other essays are devoted to early Christian music, Renaissance music, early Italian opera; Arthur Mendel writes on ambiguities of the munsural system, Edward Lowinsky on Willaert's "Chromatic Duo," Joseph Kerman on Verdi, and Elliot Forbes on Beethoven. Originally published in 1958. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
