Pastorale pour Orgue (1909) is Jean Jules Aimable Roger-Ducasse’s only solo organ composition, which demonstrates skillful use of organ colors and demands a virtuoso technique for performance. Writing Pastorale in 1909, Roger-Ducasse synthesized compositional styles and techniques of two very different compositional approaches – impressionism and classicism. This study examines the stylistic characteristics of Pastorale by Roger-Ducasse as examples of both of these influences. the synthesis in Pastorale is primarily evident in the combination of classical forms and generic references with impressionist harmony and color. Thus, examining these musical elements provides hitherto unexplored insights into Pastorale as a master solo organ work of the early twentieth century. the dissertation is divided into four chapters. the first chapter presents the purpose, the significance, and the state of research of the piece. in the second chapter, I examine the traits of classicism through genre, form, thematic variation and other classicist elements of the composition. the third chapter presents the traits of impressionism including harmonic parallelism, extended chords, pedal points, ostinatos, and whole-tone scales. in the fourth chapter, I summarize the study and make a suggestion for further research of the piece.
