"The most important study of any part of Mozart's output to have appeared for many years. Indeed, it blazes a trail. There have been books in plenty that discuss the music and the background of various groups of Mozart's works...but none, I think, until now that has applied the full rigour of modern musicological method, work by work, supported by a comprehensive grasp of the literature, both contemporary and secondary....There are, without exaggeration, hundreds of new, interesting and thought-provoking points in his discussion....Bound to be a cornerstone of Mozart scholarship for many decades and a starting-point for any future work."--Early Music

"Monumental....An admirable and exhaustive job on a subject that will serve scholars for years to come....Highly recommended."--Journal of Musicological Research

"This exhaustively researched work delivers a plethora of details about the symphonies and the composer's personal and professional life."--Symphony Magazine

"Until now there has been no really substantial book on Mozart's symphonies, but Zaslaw's work is so thorough and finely done that surely it will be the standard source on this important repertory for years to come. It is good to see such a significant gap in the Mozart research literature filled by a book that will no doubt become as indispensable in its own way as the Köchel thematic catalog or Emily Anderson's edition of the Mozart letters....A handsome volume, very reasonably priced for the riches it contains."--Choice

"Both Mozart and the symphonies are shown in an interesting new light. Thoroughly researched, clearly written, and fascinating to read, this is a welcome addition to the growing number of high-quality studies of classical composers."--Library Journal
