The music of Samuel Barber is well known in the vocal, piano, and string literature; however, little of his chamber music involves woodwinds, and in particular, only one work involves the woodwind quintet. Summer Music, originally commissioned as a septet, developed after the premiere of the work into the woodwind quintet version, with the assistance of the New York Woodwind Quintet. Barber is considered a contemporary .romantic. composer, evidenced through his use of lyricism. Summer Music, a standard in the woodwind quintet literature, should be included in every professional flutist's repertoire. The intent of this dissertation is to consider Barber's use of lyricism as a determinant of the form of Summer Music, as well as to compare the differences between the manuscript and the published edition.
