Historically, composers have used methods in addition to inspiration in writing music. Regardless of the source materials they used, composers ultimately rely on their musical sensitivity to inform the compositional decision-making. Discuses the rotational aspects of decimals that are created from certain prime-number denominators, and focuses on the prime number 17. Shows how these decimals can be transformed by converting them to different number bases. Looks at the Golden Proportion and its use in creating formal structures. Examines compositional and aesthetic issues arising from using number series to generate the pitches, rhythms, and sections in the Concerto for Organ and Orchestra. This process of composition reveals musical gestures that may not have been discovered using more intuitively based approaches to composition. Shows how musical sensitivity was necessary in shaping the numerically derived material in order to create aesthetically satisfying music.

James Sellars has established himself as one of America's foremost composers whose eclectic style reveals a wealth of influences. His artistic combination of various traditional and avant-garde techniques, along with his sensitive and expert craftsmanship has earned him an important position in contemporary American music. Sellars' compositional styles have encompassed neo-Romanticism, in his early days, through post-serialism and Dada to an eclectic, post-Romantic style utilizing popular elements including electro-acoustic techniques. His extensive catalog of over 150 compositions includes works for orchestra, opera, chorus, dance, chamber, voices with ensemble, solo voice, piano, instrumental solos, band, and media. Sellars' compositions for piano solo span a 38-year period and total 17 works, the most important of which are his six one-movement sonatas, which represent, according to Sellars, "a journey from modernism to post-modernism." Their value lies in their eclectic stylistic approaches, artistic nd technical challenges, and pianistic effectiveness. The first three sonatas, incorporating post-serial elements, fall into a modernist stylistic stance while numbers four through six, in postmodern style, contrast one another drastically. Sonata Brasileira, recalls the broad sweeping gestures of the Romantic period; Sonata V reveals the influence of the absurdist Dada movement; and the last sonata Patterns on a Field, blends …

The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other avenues of register development. If registers are laryngeally derived, there should be another way of register unification, which directly addresses the coordination of the laryngeal muscles. In support of this argument, this thesis investigates the teaching practices of a group of twentieth-century American voice teachers, who rely on intensity manipulation as the primary means for enhancing the register adjustments. Intensity exercises such as the messa di voce has long been practiced in historical pedagogy, but it is not until now that voice science confirmed its significance in register coordination.

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 …

Gottlob Harrer (1703-1755) composed at least twenty-seven sinfonias for his patron Count Heinrich von Bruhl in Dresden from 1731-1747, placing them among the earliest concert symphonies written. Harrer's mostly autograph sinfonia manuscripts are significant documents that provide us with a more thorough understanding of musical activities in and around Dresden. Several of the works indicate topical references, including dance, march, and hunt allusions, that comment on the Dresden social occasions for which Harrer composed these works. Harrer mixes topical references with other gestures in several of his sinfonias to create what I believe is an unrecognized affective language functioning in instrumental works of the time. An examination of the topical allusions in Harrer's works solidifies their connection to the social milieu for which he wrote them, and therefore better defines the genre of the concert sinfonia of the time. The first part of this study of Harrer's sinfonias addresses evidence about the composer, his patron, Dresden society, and the circumstances surrounding the first performances of several works, musical evidence of the composer's stylistic and formal approach to the genre, and the rhetorical meaning of topical gestures in the scores in ways not yet explored. In this dissertation, I demonstrate that …

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.

Examines the use of vernacular, country guitar styles in an electro-acoustic environment. Special attention is given to performance practices and explanation of techniques. Electro-acoustic techniques-including sound design and spatialization-are given with sonogram analyses and excerpts from the score. Compositional considerations are contrasted with those of Mario Davidovsky and Jean-Claude Risset with special emphasis on electro-acoustic approaches. Contextualization of the piece in reference to other contemporary, electric guitar music is shown with reference to George Crumb and Chiel Meijering.

Till Millennial Kingdom is a single-movement composition, eleven minutes in length, combining a trumpet, three percussionists, and tape. Throughout this text, use of the word "tape" will refer to pre-recorded audio on compact disk. This is also a programmatic composition, in that it uses music to depict a non-musical event. The form and instrumentation of Till Millennial Kingdom create a musical depiction of natural and supernatural events as they relate to biblical prophecy. The trumpet makes a significant thematic contribution throughout the work and particularly during the end of the piece. The use of percussion grants an element of rhythmic agitation, and the tape part provides a musical canvas upon which all sonic elements of the work are arranged. The combination of percussion and electro-acoustic gestures represents the programmatic concept of wrath and tribulation. Ironically, the closing stages of this work musically represent the beginning of eternity.

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.

The Prayer of Daniel is a chamber piece in the style of an oratorio for vocal bass-baritone soloist, flute doubling on alto flute, B flat clarinet doubling on bass clarinet, violin, cello, piano, percussion on vibraphone and marimba, doumbek (a middle eastern drum), and men's chorus (TTBB). The approximate duration is thirty minutes. The text comes from the Old Testament book of Daniel, Chapter 9 verses 4 through 19. In these passages the prophet Daniel rends from his heart a prayer of repentance, mercy and forgiveness on the behalf of a fallen nation. The harmonic language of the composition combines both classical contemporary and jazz sonorities. The rhythmic language is drawn from the meter of the text, and is used to underscore the emotion of the prayer. These elements combine to form a rich music experience that conveys the penitent heart of the prophet Daniel.

As a consequence to Gilbert and Sullivan's famed Carpet Quarrel, two operettas with decidedly "exotic" themes, The Nautch Girl; or, The Rajah of Chutneypore, and Utopia Limited; or, The Flowers of Progress were presented to London audiences. Neither has been accepted as part of the larger Savoy canon. This thesis considers the conspicuous business atmosphere of their originally performed contexts to understand why this situation arose. Critical social theory makes it possible to read the two documents as overt reflections on British imperialism. Examined more closely, however, the operettas reveal a great deal more about the highly introverted nature of exotic representation and the ambiguous dialogue between race and class hierarchies in late nineteenth-century British society.
