The period between 1880 and 1885 was a significant time in Claude Debussy's life and compositional career. 1880 marks the date of his first published composition, "Nuit d'étoiles," and 1885 is the year in which he began his two-year tenure in Rome after winning the coveted Prix de Rome in 1884. During the intervening time Debussy composed about forty songs. Scholarly literature, especially analytical literature, tends to focus heavily on music in Debussy's mature style, often casting his early compositions in an unfavorable light. Writing on Debussy is scattered with references to the early songs but authors almost always situate them on one end of a continuum that shows an evolution of compositional style culminating in maturity. Such a view tends, if only tacitly, to regard early works as inferior instances of juvenilia rather than works worthy of study in their own right. In this dissertation I establish a foundation for regarding Debussy's early songs as significant compositions in their own right, independent from anachronistic comparisons with his more mature compositional style, and provide justification for considering the songs as a unified, identifiable repertoire within Debussy's larger œuvre. Using a modified Schenkerian analytical approach, I identify consistencies among the songs …

The progressive metal style "djent" emerged in the mid-to-late 2000s with bands that modeled their use of extended range instruments and complex rhythmic cycles after that of Swedish metal band Meshuggah. The addition of a new vocabulary of melody and harmony by bands such as Periphery, Tesseract, and Animals as Leaders has come to define djent in a new way and provided fruitful ground for voice-leading and metrical analysis. In this dissertation, I approach analysis in two steps. The first step is the production of detailed transcriptions of four djent songs. The process of transcription has allowed for the development of Transcription Preference Rules, modeled after Lerdahl and Jackendoff's preference rule approach in their Generative Theory of Tonal Music. The Transcription Preference Rules account for the selection of key signatures, time signatures, and other features of the scores that may affect analysis. Second, using these scores, I examine the connection between the textual topic of change and the voice-leading and metrical structures in Periphery's "Insomnia" and Tesseract's "Of Matter." I show how this topic is reflected by techniques such as change melodic direction, multidimensional metrical dissonance, and auxiliary cadential events. Finally, I apply voice-leading and metrical analysis to Animals as …
