Composer William Bolcom (1938-) has shown a remarkable capacity for incorporating disparate materials and combining them to create original compositions, while often using traditional genres and forms. This style has earned Bolcom the reputation as a leading composer of American postmodernism. This study provides a brief sketch of Bolcom's development as a postmodern composer, his repertoire for violoncello and piano, and it examines his compositional style as applied in his Sonata for Violoncello and Piano (1989). In the Sonata Bolcom applies a wide variety of musical vocabulary from serious and popular traditions. He juxtaposes contrasting ideas to create and resolve rhythmic, melodic and harmonic tensions and amalgamates concepts of three centuries of music history into one new integral work. All these disparate elements with classical, romantic, impressionist, expressionist, modernist and popular connotations are molded together to form a serious piece of musi c with a sense of humor. The three contrasting movements of the Sonata share many common rhythmic, melodic and harmonic traits. The movements form a congruent work of Classical and Romantic spirit, often reminiscent of Brahms' music, despite the mixed use of traditional, popular, and modernist musical languages.

Kirke Mechem (b. 1925), American composer, has a musical output which includes a variety of genres, the most prolific being choral music. This document examines selected choral works by Mechem that are set to the poetry of Sara Teasdale (b. 1884, d. 1933). Included are biographical sketches of Mechem and Teasdale. Selected choral works examined include Christmas Carol (1969) SATB and guitar, The Winds of May, five movement choral cycle (1965) SATB, Birds at Dusk, from the choral cycle Winging Wildly (1998) SATB, and Barter (1995) SA, trumpet, piano 4-hands. Analysis of the poetry involved as well as musical attributes and compositional techniques, including meter, form, harmonic structures, wordpainting, rhythmic treatment and melodic characteristics are included in the discussion.

Aaron Copland has been in the forefront of the American musical scene since the 1920s. He has been called an "American composer" for his ability to formulate the essence of American folk music into a wide variety of mediums. The variety and scope of his compositions encompass a diverse array of styles and techniques. From the jazz influenced works that dominated his early period to the works for Hollywood films, from the chamber music that was directly influenced by his Jewish background to the partial acceptance of serial technique, Copland has managed to delve equally into all these styles. Yet, one could arguably rank his works for the stage as his most popular and generally most successful compositions of his career. The extent to which the American public has accepted these works as being "folk" is a case for the genius and adaptability of Copland's talent. Although works like Appalachian Spring, Rodeo, and Lincoln Portrait command the attention of the general public, of whom Aaron Copland was constantly aware, there are works for the piano that deserve and demand close study by pianists. One such work is the Piano Variations. Written in 1930, it has been acknowledged as a twentieth …

The dissertation focuses on Joe Lovano's utilization of thematic material in relation to "Misterioso" by Thelonius Monk. Thematicism is defined more broadly in this study to include reference to the form, phrase structure, and harmony of "Misterioso". Methodological models provided by Gary Potter, Henry Martin, and Paul Hindemith serve as points of departure for this study which focuses on four areas: 1) phrasing, 2) step progression, 3) motives and formulas, and 4) harmonic implications. Thematic relationships are discovered through the analysis of the transcription of Lovano's improvisation; the four levels of the analysis work together and also independent of one another to produce a kind of thematic counterpoint. This study also examines how Lovano creates an effective solo. The study will be of benefit to students, professional musicians, pedagogues, theorists, musicologists, and jazz aficionados.

This study documents and analyzes cyclic patterns used as melodic vocabulary in John Coltrane's improvisations from compositions of 1965 to 1967. The analysis is categorized in two distinct sections. The first section analyzes melodic vocabulary that is derived from the cycle of descending major thirds progressions found in the compositions of 1959 to 1960. The second section analyzes melodic vocabulary that is derived from Nicolas Slonimsky's Thesaurus of Scales and Melodic Patterns using the theoretical terminology incorporated in the treatise. Musical examples consist of patterns from the Thesaurus and excerpts from selected improvisations of John Coltrane as transcribed by Andrew White. Important scholarly contributions relevant to the subject by Carl Woideck, Lewis Porter, David Demsey, and Walt Weiskopf are included. Every effort has been made to cite interviews with musicians and commentaries by writers contemporary to that period of time with special emphasis on the important influence of Thelonious Monk, Miles Davis, and Ornette Coleman. Chapter headings include: Literature Review and Methodology; Thelonious Monk, Miles Davis, and Ornette Coleman: Converging Influences; Analysis: Coltrane's Major Thirds Harmonic Cycles Used as Melodic Vocabulary; Interval Cycles in Coltrane's Melodic Vocabulary Based on Patterns from Slonimsky's Thesaurus; Summary and Conclusion.

Several interpretations in performances, recordings, and publications of Giuseppe Verdi's Messa da Requiem raise issues concerning the relationship between these readings and the composer's intention. Understanding Verdi's tempo and phrasing in the Requiem is of crucial importance in rediscovering his intention. Knowing that Verdi's metronome markings were not merely performance suggestions but that they actually reflected his final decision is equally important. Unlike his operas, fast tempos are not introduced suddenly in the Requiem; rather, where tempo changes occur gradually from one section to the next, thereby maintaining the music's overall character. Verdi's phrasing is very subtle, and unconventional, because one sign may have multiple meanings. Compounding this complication are the many editorial errors in the published editions. David Rosen, in his critical edition, corrected many of these errors, and made additional editorial suggestions, but there are still numerous places where determining correct phrasing, as well as tempo fluctuations, knowledge of Verdi's use of signs and symbols is difficult.
