Leonard Ratner, pioneer of topical analysis, was one of the first modern scholars to insist on the importance of the musical surface in analysis; not to trivialize musical structure and process, but simply to assert that the character of a piece—the part the listener hears, in other words—is of central importance to “how it works.” Since his ground-breaking work, topical analysis and topic theory has blossomed and this conference is dedicated to exploring topic-related scholarship. We are pleased to feature a keynote address by Melanie Plesch, Melbourne Conservatorium of Music, The University of Melbourne and a plenary address by Jonathan Bellman, University of Northern Colorado School of Music. We encourage submissions from scholars, scholar-performers and students in the areas of topic theory (in its broadest sense) and its many potential applications: music analysis, music and meaning, and performance as applied to a diversity of musics including, but not limited to, Western art music, music and film, popular music, video-game music, etc. Performance-based scholarly presentations are also welcome.
