An indispensable resource on Samuel Barber's complete oeuvre-more than 100 published and nearly twice as many unpublished compositions-with an abundance of information on song texts, first performances, genesis of composition, duration, revisions, editions, arrangements, selected discography of historical and contemporary recordings, and detailed description of the hundreds of holograph manuscripts, sketches, drafts, and significant publisher's proofs founded in libraries and private collections throughout the United States. Illuminating quotations drawn from Barber's letters and diaries will be of special interest not only to scholars but conductors, composers, performers, and the general music enthusiast.
