Polyphonic Harmony in Three of Ferruccio Busoni’s Orchestral Elegies

This dissertation focuses on three of Busoni’s late orchestral works known as “orchestral elegies”: Berceuse élégiaque (Elegie no. 1, 1909), Gesang vom Reigen der Geister (Elegie no. 4, 1915), and Sarabande (Elegie no. 5, 1918-19). The study seeks to provide a better understanding of Busoni’s late style as a crucial bridge from late nineteenth-century chromaticism in the works of Liszt, Wagner, and others to the post-tonal languages of the twentieth century. At the heart of this study lies a particular concept that forms the basis of many characteristic features of Busoni’s late style, namely the concept of polyphonic harmony, or harmony as a cumulative result of independent melodic lines. This concept is also related to a technique of orchestration in which the collective harmony is sounded in such a way that the individual voices are distinct. In the highly personal tonal language of Busoni’s late works, passages often consist of a web of motives weaved throughout the voices at the surface level of the music. Linear analysis provides a means of unravelling the dense fabric of voices and illustrating the underlying harmonic progressions, which most often consist of parallel, primarily semitonal, progressions of tertian sonorities. Chapter 1 provides a backdrop for this study, including a brief summary of Busoni’s ideas on the aesthetics of music and a summary of his influence and development as a composer. Chapter 2 addresses the concept of polyphonic harmony in more detail, some theoretical ideas related to it, and characteristics of Busoni’s late style that reflect this concept. Chapter 3 is dedicated to analytical methodology, addressing concepts which emerge from various linear approaches to the analysis of some twentieth-century music. Chapters 4, 5, and 6 are each dedicated to a specific work, the purpose being to illuminate through linear analysis compositional characteristics and techniques related to the concept of polyphonic harmony, including the flexibility between the melodic and harmonic realms, chord misalignment, overlap, and superposition.
