The Works of Giuseppe Verdi is the first critical edition of the composer's oeuvre. Together with his operas, the series presents his songs, his choral music and sacred pieces, and his string quartet and other instrumental works. Based on Verdi's autograph score and an examination of important secondary sources, including contemporary manuscript copies and performing parts, this edition of Il trovatore identifies and resolves numerous ambiguities of harmony, melodic detail, text, and phrasing that have marred previous scores. Scholars and performers alike will find a wealth of information in the critical apparatus to inform their research and interpretations. The introduction to the score outlines the work's genesis, sources, and performance history, while the critical commentary discusses all editorial decisions.
