Lee, Jung-AThe purpose of my dissertation project to explore the coloratura repertoire and the technical requirements needed to sing it: a repertoire which requires flexibility to navigate through technically challenging passages as well as the skill to control the legato requirements and the freedom needed to execute, with brio, passages of the high range. This dissertation project comprises two major roles in staged performances of Der Schauspieldirektor (The Impresario), by W. A. Mozart and Lucia di Lammermoor (The Bride of larnmerrnoor) by G. Donizetti, as well as a recital presenting coloratura concert and song repertoire. These recordings are available through the Michelle Smith Performing Arts Library in Clarice Smith Performing Arts Center at University of Maryland, College Park.en-USDissertation
