This paper provides an overview of Functional Analysis, a musical analysis technique developed by the Austrian-born musician, broadcaster, and critic Hans Keller. The underlying philosophy, public and critical reception, as well as potential pedagogical applications are also surveyed. In order to explore the method further, and to provide a demonstration, a new functional analysis was composed based on Haydn’s Piano Sonata No. 12 in A Major, and is included in the appendix. The new functional analysis was composed in accordance with Keller’s writings on the topic, and was modeled after the available examples he composed himself. This research was motivated in part by what I believe are important pedagogical applications of the method, which were not explored by Keller, as Functional Analysis has the potential to offer students a subtle, integrated, and unique perspective on a composition.</p
