Written in 1970, this winner of the National Book Award is perhaps the best guide to the music of the late 18th century that the reader is likely to find. Rosen defines classical music (which, in this case, is probably more properly rendered "Classical," as it refers to that specific style) through the music of its greatest geniuses: Mozart, Haydn and Beethoven. This is serious stuff, but well worth the effort for the student of classical music. There are many printed musical illustrations; you'll get more out of this book if you read music. This volume has a logical successor in Rosen's The Romantic Generation. A revised version in hardcover is due later this year.
