This dissertation addresses specific theoretical issues within Gotkovsky's Eolienne. She was a student of Messiaen, and his influence is evident in Eolienne, but at the same time, Gotkovsky's compositional voice is both personally distinctive and reflects l'esprit de temps of the twentieth century Parisian musical world. The research provides extensive analytical insight into Gotkovsky's musical language in Eolienne, specifically her use of symmetrical scales, emphasis on timbre, and formal constructs. Because there are limited scholarly resources available on the subject of flute and harp chamber music, and a small amount of biographical information on Gotkovsky, this dissertation is a significant contribution within the area of chamber music for flute, both historically and theoretically. It provides an analysis of Gotkovsky's musical language and the analysis gives performers access to musical-theoretical information previously unavailable.
