BAROQUE MUSIC FOR TRUMPET: A STUDY OF SOLO AND CHAMBER REPERTOIRE

The trumpet experienced important changes in terms of its musical use during the middle and late Baroque period. Prior to the Baroque, and even in to the first half of the 17th century, the trumpet had historically been used for rather "non-musical" purposes, sometimes as an instrument for battle or as a tool to be used in the town square to announce the arrival of a dignitary. On the whole, the trumpet was most certainly not used as an instrument of melody -that was typically reserved for violins, flutes, and oboes. However, in the late 1600's, composers such as Allesandro Stradella and Henry Purcell began to treat the trumpet differently. They saw the melodic potential in the trumpet and began to feature the trumpet more as an instrument of melody, as opposed to relegating it to only outlining triads and emphasizing harmony. Of course, keyboard, string, and woodwind instruments had long established a significant catalogue of works by the late 17th century. Additionally, even after the trumpet had been established as an instrument of melody, prominent composers of the time still wrote significantly more solo music for these other instrument families than for the trumpet. Consequently, the overall Baroque repertoire for the solo trumpet pales in comparison to that of the other families of instruments. But, much of this Baroque literature not originally written for trumpet can be presented effectively in the form of a transcription, thereby adding greatly to the repertoire of the Baroque solo trumpet. The goal of these three dissertation recitals is twofold: 1) to perform literature that offers music from a variety of countries of origin that span the entire Baroque era and 2) to feature music that has remained relatively unknown in the trumpet world, yet is musically strong. I will also introduce viable "new" music to the trumpet repertoire through Baroque transcriptions originally written for other instruments or voice. The majority of the transcriptions I will be performing have originated from my own listening and study of Baroque music, and I have selected music that I felt would translate well for the trumpet.

SOLO AND CHAMBER CLARINET WORKS BY AMERICAN- BORN WOMEN COMPOSERS: 1990-2005

During the period of 1990-2005, American-born women composers have contributed significantly to the standard clarinet repertoire. Pioneering composers such as Joan Tower, Margaret Brouwer, and Libby Larsen have created staples for clarinet literature. Yet, there is very little scholarly research on women composers of clarinet music, most being concentrated on Joan Tower. Through my research, I have discovered over seventy-five works by more than fifty composers in the following genres: solo clarinet; clarinet and piano; clarinet and voice, with or without piano; and small chamber pieces for up to five players. This performance dissertation project consists of three recitals featuring solo and chamber works by nine living women composers, and program notes containing pertinent biographical and compositional information. My intent is to increase recognition women composers, both prominent and lesser known, who are writing high-quality, accessible clarinet literature. Each woman selected is making a full or partial living from the sales of her compositions, has received recognition through awards, commissions, grants, and frequent performances, and has composed works that are both performer and audience accessible. Recital 1: Trios for Clarinet, Violin, and Piano Commissioned by the Verdehr Trio and Composed by American-Born Women Composers. Composers: Jennifer Higdon, Joan Tower, Margaret Brouwer, and Libby Larsen. Recital II: Programmatic Clarinet Works by American-Born Women Composers. Composers: Andrea Clearfield, Stella Sung, and Karen Amrhein. Recital III: Works for Solo Clarinet, Clarinet and Piano, and Clarinet Concerto Genres by American-Born Women Composers. Composers: Persis Parshall Vehar, Jenni Brandon, Margaret Brouwer, and Libby Larsen.

THEATRICAL MUSIC FOR SOLO PERCUSSION

The act of playing percussion is innately theatrical. The motions by which a percussionist plays his instruments often resemble a carefully choreographed dance. Our bodies are freed from having to hold or blow into an instrument. We are free to move to and from our instruments, to change our facial expressions, and to vocalize. This performance dissertation consists of three recitals featuring theatrical music for solo percussion. The selections are limited to works in which the composer instructs the solo percussion performer to perform in an extra-musical capacity, whether it be by singing, speaking, moving, acting, dancing, or any other action. On all three recitals, I performed established works for solo theatrical percussion. However, on the first recital, I also played the world premiere performance of The Authors, a new work by Stuart Saunders Smith. This half-hour long marimba opera requires the solo performer to speak, sing, and act while playing the marimba. For the final recital, I featured pieces commissioned from two professional composers, John Leupold II and Daniel Adams. Through this series, I hope to both pay tribute to existing great works and to encourage new composition of solo theatrical percussion music.

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.

VIRTUOSIC ELEMENTS IN THE COLLABORATIVE PIANIST’S REPERTOIRE: SELECTED SOLO, VOCAL, AND CHAMBER WORKS OF RACHMANINOFF AND RAVEL

This dissertation project explores some of the technical and musical challenges that face pianists in a collaborative role—specifically, those challenges that may be considered virtuosic in nature. The material was chosen from the works of Rachmaninoff and Ravel because of the technically and musically demanding yet idiomatic piano writing. This virtuosic piano writing also extends into the collaborative repertoire. The pieces were also chosen to demonstrate these virtuosic elements in a wide variety of settings. Solo piano pieces were chosen to provide a point of departure, and the programmed works ranged from vocal to two-piano, to sonatas and a piano trio. The recitals were arranged to demonstrate as much contrast as possible, while being grouped by composer. The first recital was performed on April 24, 2009. This recital featured five songs of Rachmaninoff, as well as three solo piano preludes and his Suite No. 2 for two pianos. The second recital occurred on November 16, 2010. This recital featured the music of both Rachmaninoff and Ravel, as well as a short lecture introducing the solo work “Ondine” from Gaspard de la nuit by Ravel. Following the lecture were the Cinq mélodies populaires grecques and the program closed with the substantial Rachmaninoff Sonata for Cello and Piano. The final program was given on October 10, 2011. This recital featured the music of Ravel, and it included his Sonata for Violin and Piano, the Debussy Nocturnes transcribed for two pianos by Ravel, and the Piano Trio. The inclusion of a transcription of a work by another composer highlights Ravel’s particular style of writing for the piano. All of these recitals were performed at the Gildenhorn Recital Hall in the Clarice Smith Performing Arts Center at the University of Maryland. The recitals are recorded on compact discs, which can be found in the Digital Repository at the University of Maryland (DRUM).

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. The works performed and discussed in this dissertation are the following: (Recital I) Duo Concertante by Darius Milhaud; Sonata by Leonard Bernstein; Sonata for Two Clarinets by Francis Poulenc; Duos for Flute and Clarinet, Op. 34 by Robert Muczynski; Dance Preludes by Witold Lutoslawski, (Recital II) Sonatine by Arthur Honegger; Time pieces by Robert Muczynski; Suite for Clarinet, Violin and Piano by Darius Milhaud; Sonate for Clarinet, Flute and Piano by Maurice Emmanuel; Tarantelle for Flute, Clarinet and Piano, Op. 6 by Camille Saint-Saëns, (Recital III) Sonatina by Joseph Horovitz; Suite from L'histoire du Soldat for Clarinet, Violin and Piano by Igor Stravinsky; Contrasts for Clarinet, Violin and Piano by Béla Bartók The recitals that took place on December 1, 2012 and on April 25, 2013 were performed in the Ulrich Recital Hall of the Clarice Performing Arts Center in College Park, Maryland. The recital that took place on November 2, 2013 was performed at the Gildenhorn Recital Hall of the same performing arts center.

Rehabilitación de suelos salino - sódicos : evaluación de enmiendas y de especies forrajeras

La salinización de los suelos es uno de los problemas más graves de degradación en el mundo. En la Argentina hay aproximadamente 85.000.000 ha afectadas por exceso de sales y sodio. La generación de productos orgánicos como residuo de procesos industriales es vista con interés para la recuperación de suelos salino-sódicos. Por otra parte, en producciones extensivas se generan productos orgánicos con potencial de bioremediación como los biosólidos de Feedlot (BF) y los Efluentes de Tambo (BT). El objetivo de esta tesis fue investigar posibles estrategias de rehabilitación de suelos salino-sódicos, a través de la evaluación de la aplicación de enmiendas biológicas (Biosólidos de feedlot y Efluentes de tambo) y químicas (Yeso) con el fin de modificar las propiedades químicas de suelos Natracuoles y mejorar la productividad primaria de gramíneas forrajeras perennes. Para esto, se llevaron a cabo dos ensayos, uno bajo condiciones de invernáculo y otro a campo. En los dos ensayos los tratamientos fueron: testigo (T), aplicación de 8 t de materia seca (MS) ha-1 de BT, aplicación de 8 t MS ha-1 de BF y aplicación de 12 t ha-1 de Y. En invernáculo se evaluó la respuesta en biomasa aérea y radical de Thinopyrum ponticum (agropiro alargado). En el ensayo de campo se evaluó el comportamiento de las enmiendas sobre las propiedades químicas del suelo, utilizándose cobertura vegetal de cebada (Hordeum vulgare L.) y sorgo para silaje (Sorghum sudanense). En invernáculo se comprobó que los BT, los BF y el Y incrementaron la MS aérea y radical de T. ponticum. En el ensayo a campo, se comprobó que los BT, los BF y el Y, no tuvieron efecto alguno sobre las propiedades químicas del suelo. La variabilidad observada en la materia seca (MS) de S. sudanense se explicó en un 49 por ciento por el Porcentaje de Sodio Intercambiable (PSI) del suelo y la profundidad del horizonte A. Se concluye que los BT, los BF y el Y incrementaron la MS aérea y radical de agropiro bajo condiciones de invernáculo, pero a campo, no fueron efectivos en la remediación de la salinidad y la sodicidad del suelo debido a la elevada variabilidad edáfica y a la sequía ocurrida durante el período experimental, condiciones que impidieron la lixiviación de sodio intercambiado por calcio y el exceso de sales solubles, y la consecuente remediación. La falta de respuesta observada a campo fue atribuida, además a la decobertura superficial del suelo por la labranza, particularmente en suelos con delgado horizonte A
