Many of the early writings and lectures of the German phenomenological philosopher Martin Heidegger involve investigations into the question of Being. An important part of these investigations is his examination of how we go about the everyday business of existing--doing our jobs, dealing with things in our environment, working through problems, thinking, talking--and what our ways of operating in these everyday activities tell us about our Being in general. Musicians have their own everyday musical tasks, two of the most prominent of which are composing and performing. Composers and performers, like everyone else, have a 'world'--Heidegger's word for the structure of relationships between equipment, persons, and tasks and the way in which a person is situated in that structure--and that 'world' allows them to cope with their musical environment in ways that enable them to make music as composers and performers. Analyzing music is an activity that a Heideggerian approach sees as derived from the primary musical activities of composing and performing. A music analyst trades the possibility of primary musical involvement for a kind of involvement that points out determinate characteristics; hence in adopting an analytical stance, the analyst trades doing something musical for saying something about music. In making such a trade, however, a prior musical involvement--a basic musicality--is always presupposed. Every way of analyzing music has its own way of making determinations, and after detailing the manner of the derivation of the general analytical attitude, this study examines several types of analysis and the ways in which they exemplify the derivative nature of analytical activity. One extended example, an analysis of Jean Sibelius's The Swan of Tuonela, provides several opportunities for discussion (via interspersed passages of commentary) of a view of music analysis drawn from Heideggerian phenomenology.

This study explores Sibelius's last and, perhaps, most enigmatic Symphony from historical (source-critical), Schenkerian, and transtextual perspectives. Through a detailed study of its genesis, musical architecture, and meaning, the author maintains that the Seventh, its composer, and its generative process, can best be understood as a series of verges: conceptual points of interaction between two or more forces. Verges between Sibelius's nature mysticism and the dramatic biographical circumstances of the period (1914-1924), between inspired and reasoned modes of composition, between genres (symphony and fantasy), between various form types, between tragic despair and hopeful yearning, between innovation and classicism, and between a host of other seeming oppositions, all define the Seventh Symphony and illuminate various facets of the composer's life and thought.

While he was composing his important orchestral tone poem Finlandia in 1899–1900, Jean Sibelius (1865–1957) made his own piano arrangement of it. The purpose of this study is to compare the piano arrangement and orchestral version and to see further the similarities with Sibelius's other piano compositions from the same time period (1899-1904). Through this study I have found compositional patterns, which are typical for the composer and defined his composition style for piano during his "Kalevala-Romantic" phase. Sibelius's piano style was characterized as unpianistic and bulky by some. However, through my research I can show that with an analysis of certain harmonic structures, subtle use of pedal and correct voicings, his piano texture is indeed very thoughtful and transparent with a clear focus on counterpoint while remaining pianistic and comfortable to play. In order to fully understand the idiosyncrasies of the two versions of Finlandia, a detailed comparative analysis of the piano and orchestral scores is necessary. For this purpose, I primarily used the printed scores of both the piano and orchestral versions. In addition, the manuscript of the piano version of Finlandia was consulted as an important resource. From the orchestra manuscript, only one page has been found. The analysis focuses on the comparison between the textures of both versions, the score and the piano arrangement. I also applied the results of the comparison to the other scores of Sibelius's piano compositions from that time period to show his consistency in his use of the described arrangement techniques. With using the orchestration possibilities of the piano Sibelius's writing allows the instrument to stand completely on its own using all the possibilities of the piano sound while maintaining a highly pianistic texture. The goal of my research is to provide insight to understanding Sibelius's early piano style, introduce some performance practice ideas appropriate to this period, and highlight his smaller-scale works such as the character pieces and songs of this period.
