Chopin’s Third Piano Sonata, Op. 58, is the largest solo work of his late period. Chopin’s successful combination of the Classical and the Romantic aesthetic, which is explored in Chapter 1, results in an effective balancing of structural integrity and emotional fulfillment. Every movement of Op. 58 possesses qualities of movements in a traditional sonata cycle; however, the tendency to blend structural elements, the expansion of thematic material, and the postponement of climaxes contribute to Chopin’s distinctive treatment of the sonata genre. The issue of late style in Chopin’s output has recently garnered considerable attention. Most writers focus on particular compositional techniques such as the blending of musical genres and the increasing importance of counterpoint and chromaticism. New expressive elements include manifestations of a dandified aesthetic as well as emotional lassitude. These discussions are primarily related to works in Chopin’s original genres, neglecting somewhat the Third Piano Sonata, Op. 58. The second chapter of this dissertation examines the elements of Chopin’s late style present in Op. 58, emphasizing the sonata’s first three movements. These aspects of late style include blurring of genres, complex use of chromaticism, intricacy of counterpoint, textural and thematic variety, dandified impertinence, emotional lassitude and polyvalence. The employment of late stylistic features within the sonata model results in formal ambiguities, which are particularly manifest in the first movement. Chapter 3 reconsiders the movement’s thematic boundaries and especially evaluates the juncture between development and recapitulation. In Chapter 4, the last movement’s indebtedness to Chopin’s balladic model is examined. The gradual intensification of the primary theme together with the presence of a characterizing theme and dancelike episode suggest a merging of Chopin’s balladic practice with rondo form to create an end-directed hybrid structure. This study not only encourages further research into the implications of Chopin’s late style for his larger forms but also increases the variety of interpretative choices available to performers through awareness of Chopin’s stylistic features. The final chapter suggests how insights into musical structure, style, and genre might inform performances of this sonata and how these possibilities relate to a selection of recorded performances.
