ABSTRACT Joon Park takes a closer look at Steven Strunk’s innovative application of the neo-Riemannian Tonnetz to jazz. Strunk reinterprets neo-Riemannian transformations as geometric reflections—as opposed to more conventional group theory operations—showing his understanding of jazz performance practice. Park clarifies the difference between conventional methods and Strunk’s. In addition to illustrating Steve’s close accord with jazz performance practice, Park extends his work by representing Z-related sets on the Tonnetz.
