VERSATILITY IN THE MODERN PERFORMER: THREE DIVERSE OPERA ROLES

This dissertation project consisted of performances of three diverse operatic roles. The goal was to examine the challenges and benefits of performing diverse repertoire (baroque, classical, and romantic opera, in this case) and to observe how vocal and acting techniques might adjust to different styles and voice classifications. On December 3, 5, 11, and 13,2003, I performed a composite role in Fatal Song, directed by Leon Major, in the Robert & Arlene Kogod Theatre. This opera pastiche, premiered in 1996, contains spoken dialogue, and the music originates from famous eighteenth and nineteenth-century operas. I explored the challenges and benefits of playing three different, well-known opera characters within the same opera, performing four different languages within the same opera, and performing spoken dialogue in an opera. My roles in this pastiche of famous opera included Lucia from Lucia di Lammermoor by Gaetano Donizetti, Manon from Manon by Jules Massenet, and Pamina from Die ZauberJlote by W.A. Mozart. On January 28 and 29, 2005, I performed the role of Nice in Eurilla e Alcindo, a serenata by Antonio Vivaldi, in Homer Ulrich Recital Hall; musical direction by Joseph Gascho and stage direction by Kate Vetter Cain. I explored the challenges and benefits of preparing baroque ornamentation, singing without a conductor, performing an unknown work, staging a work that is not traditionally staged, singing with minimal sets and costumes, and singing with period instruments. On April 16,20, and 24,2005, I performed the role of Musetta in Giacomo Puccini's La BohBme, directed by Pat Diamond and conducted by Jeffrey Rink, in the Ina & Jack Kay Theatre. I examined the challenges and benefits of singing with a large orchestra of modem instruments, singing Puccini rubato and coordinating this with the conductor, and singing a role in one of the most well-known operas in today's repertoire. As a result of this investigation, I concluded that singing different styles, and singing outside one's voice classification, within reason, is beneficial. The knowledge, skill, confidence and insight I acquired by becoming more versatile benefited me as a performer and as a teacher.

THE ART OF TRANSCRIBING FOR HARPSICHORD

A relatively unexplored area of the harpsichord repertoire is the group of transcriptions made by J.S. Bach (1685-1750), Jean Henry d'Anglebert (1629-1691), and Jean-Baptiste Forqueray (1699-1782). These transcriptions are valuable and worth exploring and performing. Studying them provides unique insights into their composer‘s musical thinking. By comparing transcriptions with their original sources, the transcriber's decisions and priorities can be observed. The performance component of this dissertation comprises three recitals. The first features works of Johann Sebastian Bach: two transcriptions of violin concerti by Antonio Vivaldi (1678-1741), and two transcriptions of trio sonatas by Johann Adam Reinken (1643-1722). The most salient feature of Bach‘s transcriptions is his addition of musical material: ornamenting slow movements, adding diminutions and idiomatic keyboard figurations throughout, and recomposing and expanding fugal movements. The second recital features works of Jean Henry d'Anglebert and Jean-Baptiste Forqueray, two French composer/performers. From d'Anglebert‘s many transcriptions, I assembled two key-related suites: the first comprised of lute pieces by Ennemond Gaultier (c. 1575-1651), and the second comprised of movements from operas by Jean-Baptiste Lully (1632-1687). Forqueray's transcriptions are of suites for viola da gamba and continuo, composed by his father, Antoine Forqueray (1671-1745). Creative and varied ornamentation, along with the style brisé of arpeggiated chords, are the most important features of d‘Anglebert‘s transcriptions. Forqueray‘s transcriptions are highly virtuosic and often feature the tenor and bass range of the harpsichord. The third recital features my own transcriptions: the first suite for solo cello by J.S. Bach, excerpts from the opera La Descente d’Orphée aux Enfers by Marc-Antoine Charpentier (1643-1704), and two violin pieces by Nicola Matteis (fl. c. 1670-c. 1698). In these transcriptions, I demonstrate what I have learned from studying and performing the works in the first two recitals. These recitals were performed in the Leah Smith Hall at the University of Maryland on May 4, 2010; May 11, 2010; and October 7, 2010. They were recorded on compact discs and are archived within the Digital Repository at the University of Maryland (DRUM).

THE DEVELOPMENT OF THE AMERICAN SOLO TUBA REPERTOIRE

A very good case can be made that no other instrument has experienced as dramatic an increase in artistic solo repertoire as the tuba in the past sixty years. Prior to 1954, the mainstays of the tuba repertoire were trite caricature pieces such as Solo Pomposo, Rocked in the Cradle of the Deep, Beelzebub, and Bombastoso. A few tubists, seeing the tremendous repertoire by great composers written for their brass brethren, took it upon themselves to raise the standard of original compositions for tuba. These pioneers and champions of the tuba accomplished a great deal in the mid to late twentieth century. They structured a professional organization to solidify their ranks, planned and performed in the first tuba recitals at Carnegie Hall, organized the First International Tuba Symposium-Workshop, indirectly created more prestigious positions for tuba specialists at major universities, and improved the quantity and quality of the solo tuba repertoire. This dissertation focuses on the development of the solo repertoire for tuba that happened in the United States because of the tremendous efforts of William Bell, Harvey Phillips, Roger Bobo, and R. Winston Morris. Because of their tireless work, tuba instrumentalists today enjoy a multitude of great solo works including traditional sonatas, concertos, and chamber music as well as cutting edge repertoire written in many genres and accompanied by a variety of mediums. This dissertation attempts to trace the development of the repertoire presenting the works of American composers in varying genres and musical styles from 1962 to present through three performed recitals.

SELECTED TWENTIETH-CENTURY BRITISH & AMERICAN ENGLISH SONG REPERTOIRE WRITTEN FOR SOPRANO

English language song (both British and American) is influenced by a variety of cultures, races, and musical forms and has produced a broad range of song repertoire. Like songs in all countries and throughout history, these songs can be classified into three categories: imitative songs, experimental songs, and songs of individuality. Music experimentation, necessary and welcome as it is, can hardly command broad international attention. Thus, the songs of this dissertation performance project are chosen from the first and third categories: imitative songs and individual songs in the composer's own unique style. This project concentrates its exploration on twentieth-century solo songs written in English. Although twentieth-century British & American composers also produced solos and chamber music in other languages, this dissertation focuses upon their English repertoire. This performance project consists of three programs: one British repertoire and two American. The first program titled An Evening of British Song examines twentieth-century British song written by Roger Quilter, Peter Warlock, William Walton, Benjamin Britten, Thomas F. Dunhill, Ivor Gurney, and Frank Bridge. It was presented on December 12, 2001, in Homer Ulrich Recital Hall with the collaborative pianist Meriel Owen. The second program titled An Evening of American Song I comprises music written by Dominick Argento, Samuel Barber, Ned Rorem, Leonard Bernstein, and Lee Hoiby. It was presented on October 23, 2002, in Joseph & Alma Gildenhorn Recital Hall with the collaborative pianist R. Timothy McReynolds. The third program titled An Evening of American Song II written by John Duke, John Corigliano, Charles Ives, Richard Hundley, Lori Laitman, Frederick Loewe, George Gershwin, and Jerome Kern was presented on December 18, 2003, again in Joseph & Alma Gildenhorn Recital Hall with the collaborative pianist R. Timothy McReynolds and the flutist Jessica Dunnavant. Each of these three dissertation recitals occurred at the University of Maryland in College Park and was recorded. These CD recordings are held by the Michelle Smith Performing Arts Library at the University of Maryland.

Increasing Stability of Lithium-Ion Batteries with Ordered Graphene Silicon Negative Electrodes

Currently, lackluster battery capability is restricting the widespread integration of Smart Grids, limiting the long-term feasibility of alternative, green energy conversion technologies. Silicon nanoparticles have great conductivity for applications in rechargeable batteries, but have degradation issues due to changes in volume during lithiation/delithiation cycles. To combat this, we use electrochemical deposition to uniformly space silicon particles on graphene sheets to create a more stable structure. We found the process of electrochemical deposition degraded the graphene binding in the electrode material, severely reducing charge capacity. But, the usage of mechanically mixing silicon particles with grapheme yielded batteries better than those that are commercially available.

THE PIANO FANTASY FROM BACH TO DANIELPOUR

The Fantasy, as the term suggests, is a genre that composers have found congenial for exploring innovative and imaginative processes. Works in this genre are numerous in the solo piano literature, and extend even to works for piano and orchestra and to chamber music with piano. I was curious to explore how a specific genre of music maintained similar characteristics but evolved over time. A fantasy is primed to be inventive and I wanted to see how composers from different eras and backgrounds would handle their material in this genre. I have learned that composers worked through formal developments while making innovations within this genre. The heart of my dissertation is presented through the recording project. Because ofthe abundance ofpiano fantasies, many works had to be excluded from this project for time's sake. On two compact discs, I have recorded approximately two hours of solo piano music. I have included some shorter fantasies to magnify significant developments from era to era, country to country, and composer to composer. The first disc has recordings of eighteenth and nineteenth-century fantasies: Chromatic Fantasy and Fugue, BWV 903 by J.S. Bach (1685-1750); Fantasia inC major, H. XVII, 4 by Franz Joseph Haydn (1732-1809); Fantasy inc minor, K. 475 by Wolfgang Amadeus Mozart (1756- 1791); Fantasia inf-sharp minor, Op. 28 by Felix Mendelssohn (1809-1847); and Polonaise-Fantaisie in A-flat major, Op. 61 by Frederic Chopin (1810-1849). On the second disc I have included mid-19th, 20th and 2151-century piano fantasies: Fantasy and Fugue on the Theme B-A-C-H by Franz Liszt (1811-1886); Fantasia Baetica by Manuel de Falla (1876-1946); Three Fantasies by William Bergsma (1921-1994); Fantasy, Aria and Fugue by Frederic Goossen (1927-2011); and Piano Fantasy ("Wenn ich einmal sol! scheiden") by Richard Danielpour (b. 1956). The accompanying document includes program notes for each of the pieces recorded. They were recorded on a Steinway "D" in Dekelboum Concert Hall at the University of Maryland by Antonino D'Urzo ofOpusrite Productions. This document is available in the Digital Repository at the University of Maryland and the CO's are available through the Library System at the University of Maryland.

Tracing Neoclassical Influences in selected solo and chamber music for the clarinet

The musical period of Neoclassicism began in the 1920's, between the first and second world wars. It was initiated by French composers and eventually spread to other countries. One of the most important themes to emerge from the movement was to escape from the formless, rather emotional music of the Romantic era and instead, emphasize balance, order, objectivity and clarity in musical form. Many popular clarinet repertoires are enjoyed by performers and listeners because the music is enjoyable to play and easy to listen to. In particular, classically influenced clarinet music is quite interesting because it features musical elements from both the past and contemporary musical styles. For instance, some composers have integrated preexisting, more traditional styles of composition with lighter styles of modern culture such as popular music and Jazz. It is difficult to discover purely neoclassical clarinet repertoires even though many composers created their pieces during the neoclassical era. What we most commonly find are both neoclassical and non-neoclassical influences in compositions from that time period. Thus, I aim to trace the influence of neoclassicism in selected clarinet repertoires that exist today. It is my hope that increased awareness and knowledge about accessible clarinet music may encourage the general public to develop a deeper interest in a wider sphere of clarinet music, beyond what is considered popular today.
