Tristan und Isolde is quite possibly Wagner's finest achievement. In fact, it holds a unique place in operatic history; it has inspired the thinking of philosophers, even scientists, just as works such as Oedipus Rex, Hamlet and Don Giovanni had done before. No opera lover's book shelf is complete without a copy of this score. Dover's edition is a reprint of the reliable C.F. Peters edition from the early twentieth century. The scholarship is highly reliable as is generally true with Peters, especially with Peters' German scores. There is an English translation of all German frontismatter, but no glossary of German musical terms. The cover art for this edition is Der Kuss in Gustav Klimt, an art work as erotic and disturbing as this Opera is. The score is too big, and the book too small for podium use, but it is perfect for at home. Many of the innovations of twentieth century music and drama, indeed all twentieth century culture, may never have occurred if this opera had not been written. If that sounds far-fetched, buy this score, and a good recording, and see why I make that assertion.
