The target of this thesis is to research and inquire Franz Liszt’s Année de Pélerinage, Premiére Année - Swisse “Vallée d’Obermann” and to discuss its origins from the literary beauty and style of the poems of Etienne de Senancour and Lord Byron. This thesis will research Liszt’s works through in-depth analysis from the point of view of its original poems and literature. Liszt’s historical background and musical compositions will be summarized in four chapters as a way of introducing Liszt. The first chapter overviews Liszt’s life and his music compositions. The second chapter classifies Liszt’s piano works such as virtuoso pieces, 19th-century piano character pieces, piano sonatas exemplary of the Classical period, and religious works. The third chapter analyzes the musical structure and background of Année de Pélerinage, Premiére Année – Swisse “Vallée d’Obermann.” The final chapter discusses the combination of its musical writing with poetry.
