Opera performances are often radically inventive. Composers' revisions, singers' improvisations, and stage directors' re-imaginings continually challenge our visions of canonical works. But do they go far enough? This elegantly written, beautifully concise book, spanning almost the entire history of opera, reexamines attitudes toward some of our best-loved musical works. It looks at opera's history of multiple visions and revisions and asks a simple question: what exactly is opera? "Remaking the Song", rich in imaginative answers, considers works by Handel, Mozart, Donizetti, Verdi, Wagner, Puccini, and Berio in order to challenge what many regard as sacroscant: the opera's musical text. Scholarly tradition favors the idea of great operatic texts permanently inscribed in the canon. Roger Parker, considering examples ranging from Cecilia Bartoli's much-criticized insistence on using Mozart's alternative arias in the "Marriage of Figaro" to Luciano Berio's new ending to Puccini's unfinished "Turandot", argues that opera is an inherently mutable form, and that all of us - performers, listeners, scholars - should celebrate operatic revisions as a way of opening works to contemporary needs and new pleasures.
