This document investigates the six piano etudes that have been written to this point (1995-2003) from an envisioned set of 12 Piano Etudes composed by Korean-born composer Unsuk Chin (b. 1961), one of the most accomplished composers of the twenty-first century. These etudes are an excellent case study in Chins developing musical language. They synthesize elements from around the world (scales, rhythms, and harmonies) with influences from composers such as her teacher, Gyrgy Ligeti. They also reflect her experiments in sound created through her electro-acoustic work. This study provides a brief biography of Unsuk Chin, along with an introduction to her published works. This is followed by a detailed discussion of the six piano etudes. The main body of this study is an analysis of all six etudes with respect to their formal structures, unique harmonic language, and rhythmic virtuosity. Each analysis is followed with performance suggestions to enable pianists to approach the technical difficulty of each work.
