Samuel Barber: A Thematic Catalogue of the Complete Works is the first publication to list the entire musical output of Samuel Barber, one of the most beloved and frequently performed American composers. In this exhaustive study, renowned Barber biographer Barbara Heyman chronologically lists and details hundreds of core repertory and the most recently published works, as well as numerous works previously unknown and unpublished. Each entry includes information about first performances, commissions, and the circumstances and inspiration of the composition; the texts of songs; a musical extract containing the opening measures of each work, movement, or major aria; duration, revisions, editions, arrangements, and a select discography of historical and contemporary performances. The descriptions of manuscript sources provide details about the hundreds of holograph manuscripts, sketches, drafts, and significant publishers proofs with Barbers corrections. Entries are enhanced by Heymans extensive commentary, which draws from Barbers correspondence, interviews, and diaries. Useful appendices to the catalogue comprise a register of works by genre; an alphabetical directory of works; an index of first lines of vocal works; a listing by nationality of authors and translators of texts set by Barber; and a comprehensive discography. This thematic catalogue is an invaluable guide for musicians, scholars, and students, providing an essential foundation for any serious study of Barber and his music.
