I finally decided to move along from Wagner and Strauss and tried to get into atonal opera. So I bought a CD of Berg's "Wozzeck" and tried listening to it. It definitely wasn't an easy task and so I consulted this book to help me understand the opera better. It really helped. The book introduces you to Berg's life and the situation in Vienna around the time of the opera's composition and spends some time discussing the original play on which "Wozzeck" was based, all of which set me in the right mind-frame to listen to the opera. The structural elements are presented very clearly and the most important of them are explained. There are books in which the form of the opera is analysed in more detail, but this books just gives you enough to absorb if you are a newcomer to Berg. Once you've read this book and started to enjoy "Wozzeck", the next wonderful reading would be George Perle's "The operas of Alban Berg". This book goes into much more detail and the analysis is quite impressive, but requires an extensive musical background to understand all the intricacies of the form.
