Kaikhosru Shapurji Sorabji (1892-1988) was an English composer-pianist of Parsi descent. Although he composed many works for piano, these compositions remain largely unknown to the public due to the composer's self-imposed 40-year ban on public performances of all his works and the immense technical difficulty of his music. This research proposes a comparative study of Sorabji's two versions of Rapsodie espagnole de Maurice Ravel-Transcription de concert pour piano (1923, 1945). These transcriptions are based on Ravel's orchestral work and are different in terms of the style of their arrangements: the 1923 version is more of a literal transcription, whereas the 1945 version has been expanded upon the former. This dissertation compares the differences between the two versions, as well as identifying how Sorabji infused his own style into the 1945 transcription. This study relies on primary sources including writings and manuscripts of Sorabji, and secondary sources such as articles on interpreting Sorabji's piano works and biographies about Sorabji.

The purpose of this dissertation is to offer a pedagogical guide to Woodsprite and Waterbug Collection (1977) by Dan Beaty (1937-2002) through an analysis of its pedagogical values and teaching applications. This set consists of twelve short, intermediate-level pieces, featuring various contemporary idioms. Each piece is also pedagogically written to help intermediate students to refine specific pianistic techniques beyond the elementary level. In addition, Beaty's collection expands students' musical vision and musicianship for more advanced studies via the incorporation of contemporary music theory and techniques. These qualities make Woodsprite and Waterbug Collection a valuable tool for intermediate piano students. It is also useful for instructors searching for repertoire to introduce contemporary idioms. The author hopes that this study will encourage performers, teachers and scholars to consider this work and Beaty's other piano compositions. By studying Woodsprite and Waterbug Collection, students will be more appreciative of contemporary repertoire and will welcome learning similar pieces in the future.

Unsuk Chin (b.1961), a Korean-born woman composer, was a student of Gyorgy Sandor Ligeti (1923-2006). Chin's work reflects the influence of Ligeti but also undeniably has its own style. This study investigates the six piano etudes so far published from 12 Piano Etudes (1995-2003) by Unsuk Chin and compares them with Ligeti's piano etudes to highlight the influence of the teacher on the student and to aid pianists in facing the unique technical challenges posed by both sets of etudes. The practice guide provided in this study for each specific technical difficulty requires a degree of patience from a student which, if followed, will enhance the performance.
