TALLY HORN! ECHOES OF HOOFBEATS AND HAUNTS: RECORDED SELECTIONS FOR HORN AND PIANO

In the 17th and 18th centuries, the European hunting horn was an instrument associated with the thrill of the chase, rustic scenes, and the pageantry of royal hunts. The sound of this horn and the music that evolved from its heritage would inspire composers writing for the modern horn. TALLY HOrn! Echoes of Hoofbeats and Haunts: Recorded Selections for Horn and Piano are two compact discs of works for horn and piano as well as solo horn reflecting this association with the hunt and include additional works of expressive contrast – lyrical pieces and nocturnes. Nine of the pieces reflect the modern horn’s beginnings and they are Abbot’s Alla Caccia, Berge’s Horn-Lokk, Boutry’s Chassacor, Bozza’s En Fôret, Büsser’s La Chasse de St. Hubert, Pessard’s In the Forest, Piantoni’s Air de Chasse, Schmid’s Im Tiefsten Walde, and Vinter’s Hunter’s Moon. By contrast, three of the selections, Gliére’s Nocturne, Strauss’ Nocturno, and Van Ecchaute’s Nachtpoëma are nocturnes that showcase the expressive quality of the horn. In addition, Bush’s Autumn Poem, Bacon’s Song After the Rain, and Webber’s Summer Pastures are included for their lyric qualities and evocations of nature. The largest work of the project is John Williams’s Concerto for Horn. Its five movements feature both hunting horn traits and expressive qualities. Alejandro Hernandez-Valdez and Grace Cho were the two pianists engaged for the recording. The recording engineer was Edward Kelly. The producer was Carlos Rodriquez. The pieces were recorded at the Spencerville Seventh-day Adventist Church sanctuary in Spencerville, Maryland between November 2010 and February 2011.

WORKS FOR HORN BY AMERICAN WOMEN COMPOSERS

This performance dissertation consists of three recitals featuring the music of American women composers of the 20th and 21st centuries. My purpose in presenting these recitals is to expose and explore the lesser known compositions of these composers through live public performances. I selected a cross section of composers whose compositions employed a wide range of musical styles, techniques and instrumentation. The instrumentation included not only the "standard" works for solo horn and horn and piano, but various chamber compositions as well. Of these chamber works, there exists a duet for horn and harp, a trio for violin, cello and horn, and a quartet for viola, horn, piano, and percussion. In addition to the published works chosen, it was my intent to further heighten the awareness of American women composers through the commissioning of a work specifically for this dissertation. The resulting piece was Arbor for horn and harp by Elisabeth Mehl Greene, which received its premiere on April 18, 2009. Through this project, it is my hope to have not only increased the public's awareness of these lesser known works but to have contributed to the performances of these ever growing number of works by American women composers.

Time Reversed Electromagnetic Wave Propagation as a Novel Method of Wireless Power Transfer

We investigate the application of time-reversed electromagnetic wave propagation to transmit energy in a wireless power transmission system. “Time reversal” is a signal focusing method that exploits the time reversal invariance of the lossless wave equation to direct signals onto a single point inside a complex scattering environment. In this work, we explore the properties of time reversed microwave pulses in a low-loss ray-chaotic chamber. We measure the spatial profile of the collapsing wavefront around the target antenna, and demonstrate that time reversal can be used to transfer energy to a receiver in motion. We demonstrate how nonlinear elements can be controlled to selectively focus on one target out of a group. Finally, we discuss the design of a rectenna for use in a time reversal system. We explore the implication of these results, and how they may be applied in future technologies.

What's the Matter with Extended Techniques? Getting Beyond the Stigma in the Horn and Percussion Repertoire

For this project I prepared a series of recitals featuring music for horn and percussion, in which the horn part featured extended horn techniques. For this project, I considered anything beyond the open or muted horn an extended technique. These techniques range from the common hand-stopped note passages to complex new techniques involving half-valves, multi-phonics, and more, for new sounds desired by the composer. There are several pieces written for solo horn and percussion, with ensembles ranging from simple duets to solo horn with a full percussion ensemble. However, few include extended techniques for the horn. All of these select pieces are lesser known because of their difficulty, primarily because of the challenge of the extended techniques requested by the composer. In the introduction to this paper I give a brief background to the project, where the current repertoire stands, and my experiences with commissioning works for this genre. I then give a brief history and how-to on the more common extended techniques, which were found in almost every piece. I separated these techniques so that they could be referenced in the performance notes without being extremely repetitive in their description. Then follows the main performance notes of the repertoire chosen, which includes a brief description of the piece itself and a longer discussion for performers and composers who wish to learn more about these techniques. In this section my primary focus is the extended techniques used and I provide score samples with permission to further the education of the next musicians to tackle this genre. All works performed for this project were recorded and accompany this paper in the Digital Repository at the University of Maryland (DRUM). The following works were included in this project: o Howard J. Buss, Dreams from the Shadows (2015) o Howard J. Buss, Night Tide (1995) o George Crumb, An Idyll for the Misbegotten, trans. Robert Patterson (1986/1997) o Charles Fernandez, Metamorphosis: A Horn’s Life, “Prenatal and Toddler” (2016, unfinished) o Helen Gifford, Of Old Angkor (1995) o Douglas Hill, Thoughtful Wanderings… (1990) o Pierre-Yves Level, Duetto pour Cor en Fa et Percussion (1999) o David Macbride, Elegy for Horn and Timpani (2009) o Brian Prechtl, A Song of David (1995) o Verne Reynolds, HornVibes (1986) o Pablo Salazar, Cincontar (2016) o Mark Schultz, Dragons in the Sky (1989) o Faye-Ellen Silverman, Protected Sleep (2007) o Charles Taylor, Sonata for Horn and Marimba (1991) o Robert Wolk, Tessellations (2016) With this project, I intend to promote these pieces and the techniques used to encourage more works written in this style, and reveal to fellow horn players that the techniques should not prevent these great works from being performed. Due to the lack of repertoire, I successfully commissioned new pieces featuring extended techniques, which were featured in the final recital.
