This dissertation presents analyses and musical scores for three original compositions for percussion ensemble – Tablet 7055 (2020), Fountain (2021), and Boal Machines (2020). The analyses include explanations of the works' conceptual motivations, instrumentations, musical materials, developmental processes, structures, and uses of live electronics. As a set, these pieces illustrate core aesthetic principles in my artistic practice as well as various approaches to arranging performer action and interaction in experimental percussion music.
