While Vienna certainly served as the primary center for Beethovens music world, his hometown of Bonn left an indelible mark on the composers life. One of his original worksthe Wind Octet, Opus 103and its recompositionthe String Quintet, Opus 4serve as model representatives for two completely different cities, times, and, in a sense, composers. An in-depth comparison of the Octet and Quintet reveals a great deal of change in Beethoven and his compositional style and approach from Bonn to his early time in Vienna. The arrangement of the Octet into the Quintet is a unique opportunity to gain insight into Beethovens development as a composer. The fact that the musical ideas from a completed unpublished work were allowed to freely gestate is remarkable. The differences found between the Octet and Quintetparticularly in terms of melody, harmony, structure, and motivic usageeffectively show the development of his compositional style during his formative years. Beethovens insatiable desire to reshape his music allowed the Quintet to serve as the perfect instrument to incorporate and adapt the Octets preexisting musical ideas. This music more aptly suited not only Beethovens tastes at the time, but also the very concepts that would go on to define him as one of the most remarkable and influential composers in the history of western art music. While there is extant research that uses the Octet and Quintet to compare Beethovens late Bonn and early Vienna compositional styles, a comprehensive comparison of each movement is currently not available. This document serves four purposes. First, it presents a detailed factual history of both works. Next, the paper details current scholarship and its trends regarding Beethovens arrangements, specifically the Octet and Quintet. Third, this dissertation provides an in-depth look into the differences between the two works in their entirety in order to more effectively focus on the specific musical changes Beethoven exhibited while arranging the Quintet. Lastly, this dissertation will present a guide to performing the Octet, specifically the works interpretational and logistical issues.
