This paper examines the generic aspect of Beethoven's Opus 5 Cello Sonatas (1796) from structuralist and post-structuralist perspectives, and explores the works from these viewpoints in order to gain insights into how the sonatas function as autonomous musical texts rather than historiographic documents of Beethoven's biography or transitional contributions in the development of the genre of the solo sonata as it was later cultivated. The insights offered by these perspectives argue for a reconsideration of the conventional notions of "work" and "text," which underscore the doctrine of work-immanence. This perspective also offers insights that have proven elusive when the works are considered primarily in the context of the historical-biographical construct of Beethoven's three style-periods. By applying the aesthetic practice of expressive doubling prevalent at the turn of the nineteenth century to Beethoven's Opus 5 Sonatas, a deeper understanding of the constellation of the duo sonatas in accompanied keyboard literature will be attained. Also, by illuminating the relational nature of meaning realized within a textual framework, this study attempts to enlarge the restricted scope of interpretation conventionally imposed on the Opus 5 sonatas.

Over the last quarter-century, scholars have taken a unified approach in discussing form in Italian and French opera of the nineteenth century. This approach centers around the four-part aria and duet form begun by Bellini, codified by Rossini, modified by Verdi, and dissolved by Puccini. A similar trajectory can be seen in French opera in the works of Meyerbeer, Gounod, and Massenet; however, only Meyerbeer and Gounod have received significant critical attention. This is in part due to Massenet's reception as a "composer for the people," a title ill fitting and ripe for reconsideration. This dissertation will examine duet forms in Massenet's oeuvre and will focus on the gradual change in style manifest in his twenty-five operas. Massenet's output can be divided into three distinct periods delineated by his approach to form. Representative works from each period will show how he inherited, interpreted, thwarted, and ultimately rewrote the standard formal conventions of his time and in doing so, created a dramaturgical approach to opera that unified the formerly separate number-based elements. Massenet's longevity and popular appeal make him the quintessential French opera composer of the fin de siècle and the natural choice for examining reconstructed conventions.
