Colombian composer Jaime León (1921-2015) is known for his art songs. Most of the current scholarly literature about León defines him as a nationalist composer even though a majority of his songs do not appear to have nationalist traits. This document examines a representative selection of León's songs divided into three categories: songs influenced by the bambuco (the Colombian genre most present in his songs); songs whose text refers to Colombian culture; and songs without Colombian elements present in their text or music. After examination of these songs, my conclusion is that León, rather than being nationalist, was a cosmopolitan composer who used national elements as rhetorical tools in an isolated and experimental way.

This dissertation provides an interpretive guide to Variationen und Fuge über ein Thema von Händel, Op. 24, written in 1861 by Johannes Brahms (1833–1897), in orchestral terms, using as basis the orchestral transcription by Edmund Rubbra (1901–1986), published as his Op. 47 in 1938. Not only does Brahms' Variationen present players with considerable pianistic difficulties, its intense harmonic and polyphonic structures make the music sound symphonic. The English composer Edmund Rubbra, a great Brahms enthusiast, transcribed the work for orchestra. The transcription in effect represents Rubbra's interpretation of the piano work as well as his respect for it. When both orchestra and piano versions of a composition exist, pianists may obtain essential musical ideas from studying the orchestral version, just as it is advisable for conductors to study the piano versions of symphonic works, not only those arranged by the composer. Brahms himself was not only a composer but also a pianist and conductor. It is possible that he imagined orchestral sound when composing large-scale piano works such as his Variationen. New experiments in interpretation can offer a refreshing perspective. This study focuses on elements from Rubbra's orchestral version of Variationen that can inform pianists' interpretation.

Bohuslav Martinů's "Concerto for Oboe and Small Orchestra" is one of the most frequently played pieces in the oboe repertoire. For this reason, it is often played with the piano reduction instead of the orchestra in oboe recitals. However, the existing piano reductions include many errors and discrepancies from the orchestral score, misrepresent the orchestration, sometimes fail to make the oboe entries clear, and tend to be unplayable for pianists. Moreover, the scores were published after the composer's death without him supervising the final editing. I have prepared a new, playable piano reduction to represent the orchestration more faithfully and help pianists work with their soloists more easily. Based on the work of Martin Katz, a prominent collaborative-pianist, I establish four principles for creating a new piano reduction. After scrutiny of the deficiencies of existing piano reductions, I suggest solutions for making the passages in question practical and bringing out the leading voices clearly so that the soloist can join in as easily as playing with an orchestra. To aid in reflecting the orchestral texture that Martinů created, I include abbreviated instrument names in many passages to help pianists to understand how to create balance. I have changed some passages …

In the world of chamber music, programmatic suites are more rarely composed and consequently more rarely presented in recital than other musical forms. Perhaps partially for this reason, George Enescu's Impressions d'enfance for violin and piano, his last chamber piece written in the tumultuous year of 1940, has been overlooked for a long time; even the composer himself did not make a recording of this seldom performed piece. This dissertation examines Impressions d'enface in order to explore the relationship between the underlying Romanian folk rhythmic and melodic patterns, to provide an analysis, as well as to serve as a performance guide to assist performers in surmounting the technical challenges and thus create a more effective ensemble. I hope this dissertation will encourage more duos to experiencing the joy of George Enescu's richly fulfilling Impressions d'enfance for themselves.

A Poem Carved in Stone, a work for piano solo by Washington DC-based Chinese composer Wu Yiming was composed in Spring 2020 and is dedicated to the author of this dissertation. The piece is inspired by the poetry of Han Shan, a recluse who lived during the Tang Dynasty (618-907 A.D.). His poetry is in Chan (Zen) tradition. Wu depicts the imagery and philosophy in Han Shan's poetry through highly complex rhythms, extreme sound effects and pitches, tone clusters, and extended piano techniques. This dissertation provides practical instructions for achieving these effects and executing the unconventional techniques found in this piece, which include playing inside of the piano, various standing and sitting positions, and coordination and balance. A guide to interpret this piece is from both the composer's and the performer's perspective. Observations are drawn directly from communications and coaching received from the composer. This study briefly explores the historical and cultural context of Han Shan's poetry and discusses how Wu's use of modern western compositional devices reflects the Zen philosophy. An interview with the composer is included along with an overview of both his compositions and those of composers who influenced him. It is hoped that this dissertation will …
