Fifty years ago, we embarked on a journey for the first time in all of history \u2014 an exploration of the final frontier: outer space. Now, having been to the moon and back, we are still exploring the unknown. In the 21st century, we have pioneered genetic cloning and made other unprecedented biotechnological advances. Similarly, artists have ventured into their own frontier, branching out of their own narrowly defined areas and breaking down barriers \u2014 barriers between art and science, between the concert hall and the outdoors, between manmade instruments and the sounds of nature. At first glance, it seems that music and science have little in common. But upon closer inspection, one will discover that there are similarities and intersections between these two fields that deserve attention. Interest in the correlation between music and science can be traced back at least as far as Ancient Greece; since Pythagoras, mathematicians, physicists, acousticians and many others have addressed connections between the two fields in manifold ways. It is becoming increasingly obvious that art and science are not at the opposite ends of the spectrum, where conventional wisdom has traditionally located them, but at the opposite sides of the same coin. In my thesis, I seek to explore the connections between music and the sciences by examining the field of acoustic ecology. I will first provide an overview of music as an interdisciplinary field. Then I will undertake two case studies of musicians whose endeavors have been significant to the field of acoustic ecology, and consider the benefits that can be drawn from their work. These artists are David Dunn and Andrea Polli. I will draw on their philosophy, writings and art as well as on secondary literature. I will take a philosophical approach to the intersections between the two areas and identify heretofore little explored aspects of the interdisciplinary potential of these two fields.

I am interested in performance that includes multiple artistic media. I am looking for a way to communicate with other artists that can clearly express the meaning of an artistic gesture that they can interpret for their medium. I wish to make transmedia performance art with a meaning that is clear to an audience. That meaning can be abstract. Sometimes we call art "abstract" to imply that it has no perceivable meaning. However, everything has meaning. Even if a piece of art does not have narrative meaning, we can still perceive a structure. That is thanks to our imagination. Imagination is our way of making sense of our experience. I believe that if I can identify some of the imaginative structures through which I perceive and understand my own work, I can use those structures to annotate or organize scores for improvised performance pieces. I am interested in how we understand art. One theory of understanding, which comes from Mark Johnson, involves "image schemata." Image schemata (sing. schema) are basic, abstract structures that we develop based on what we perceive from our physical interactions with the environment. We project these structures that come from a physical domain onto the mental domain. Johnson calls this process "metaphorical projection," and he calls our ability to do this "imagination." By metaphorically projecting image schemata from one domain to another, we form meaning of our experiences, and thus contribute to our understanding of the world. I believe that I can use image schemata to explain the meanings inherent in the art I make and to explain the connections in meaning between one artistic medium to another. I wish to apply this in a transmedia performance setting. First, I will analyze previous transmedia works in terms of image schemata. Second, I will make a score using image schemata for an improvised performance. Third, I will reflect on the results of attempting to rehearse that score.

Piano Quintet> is a three movement piece, inspired by music of Eastern Europe. Sunrise in Hungary starts with a legato song in the first violin unfolding over slow moving sustained harmonics in the rest of the strings. This is contrasted with a lively Hungarian dance which starts in the piano and jumps throughout all of the voices. Armenian Lament introduces a mournful melody performed over a subtly shifting pedal tone in the cello. The rest of the voices are slowly introduced until the movement builds into a canonic threnody. Evening in Bulgaria borrows from the vast repertoire of Bulgarian dances, including rhythms from the horo and rachenitsa. Each time that the movement returns to the primary theme, it incorporates aspects of the dance that directly preceded it. The final return is the crux of the piece, with the first violin playing a virtuosic ornaments run on the melody.

Nelson Rolihlahla Mandela was born July 18, 1918 into the Madiba clan in Mvezo, Transkei, South Africa. Mandela was a lawyer by trade and a freedom fighter who envisioned freedom and equality for all South Africans regardless of race. In 1965, Mandela was imprisoned at Robben Island for twenty-seven years for treason and terrorist activities against the South African apartheid regime: he was assigned prison numbers 46664. In 1992, Mandela was released from prison and two years later not only became the first democratically elected president of South Africa, but also its first black president. "Madiba 46664" is an eight-minute chamber work scored for flute, oboe, clarinet in B-flat, and bassoon; vibraphone, and two percussionists; piano; violins, violas, and celli. The work blends traditional South African rhythms of the drumming culture with elements of Western harmony and form in contrasting textures of homophony, polyphony and antiphony. "Madiba 46664" utilizes Mandela's prison number, birthdate and age (at the time the composition process began in 2013) for the initial generation of meter, rhythm, harmony, melody, and form. The work also shares intercultural concepts that can be seen in the works of three contemporary African composers, South Africans Jeanne Zaidel-Rudolph and Andile Khumalo, and Nigerian Ayo Oluranti. Each section represents a period of Mandela's life as a freedom fighter, a prisoner, and a president. The inspiration stems from the composer's discussions with Mandela soon after his release from prison and prior to his presidency. These lively discussions pertained to the state of traditional music in then apartheid South Africa and led to this creation. The conversations also played a role in the creative process.

Since 1999, a small group of groundbreaking orchestral works for turntables and orchestra has surfaced on the concert stage. These compositions explore the possibilities of the turntables and invite an intriguing fusion of musical cultures of the classically trained musician and the hip-hop DJ. Since DJ turntablists typically follow an improvised tradition and do not read music, the composer must find an effective means of notating the turntables and collaborate with the turntablist in the execution of the work. As interest in turntables composition grows, there is a need for discussion and a compositional guide with advice based on present day works. In effort to contribute a guide for turntablism composition, my research includes a historical and composer perspective that discusses turntables techniques, operation of the equipment, digital technology, hip-hop background, history of the instrument, and works of the past and present with musical excerpts pertaining to the notation and use of the turntables. Specific sources include: RPM by Nicole Lizée, Concerto for Trumpet, Turntables, and Orchestra by Paul Leary, Concerto for Turntables and Orchestra by Gabriel Prokofiev, and Stephen Webber's turntable method book The Art of the DJ Turntable Technique. Interviews with composers Prokofiev, Lizée, and Leary have provided important primary source information regarding their experience with turntablism composition and performance. Unrelated to the above research and attached as an appendix, my composition Andrew's Ritual for Bedtime for chamber orchestra is a single movement for choreographed dance that depicts a mother preparing her energetic young son for bed. The title references the nightly rituals parents undertake in order to prepare their children for bedtime.

THE PEACOCK FLIES SOUTHEAST is a work for Qudi and orchestra inspired by an ancient Chinese love story of the same title. The Qudi is also known as the "Chinese bamboo flute." It is similar to the Western piccolo. However, it has open tone holes with greater ability to bend pitches. The Qudi sounds one octave above the written music with arrange from A4 to G7.

Christopher Caliendo is a guitarist/composer who has written for a variety of performance mediums. His works been performed on international concert stages and recorded for film and television media. His compositions have garnered him the Henry Mancini Award for Film Composition, the Artin Arslanian Scholarship for Humanities, and the Peabody Grant for Scholarship. He has also received two commissions from the Vatican in 1992 and 1995. In 1988, he received an Emmy nomination for his work with the television series Paradise. The purpose of this project is to present a study of selected clarinet works by Christopher Caliendo: The Tango Concerto No. 1 is a three-movement work that Caliendo arranged for clarinet and piano in 2010, The Little Gypsy was written for solo clarinet, and Jal, Ven a mis Brazos, Amanacer, La Milonga, Acariciame, Amor Perdido, Caliente, Impulso, and Passione comprise a series of nine guitar/clarinet duos that were composed or arranged between 2009 and 2010. The document is comprised of a brief description of the career and compositions of Christopher Caliendo, a performer's guide to the selected works, a track listing for the performance recording, and a list of Caliendo's other clarinet and chamber music compositions that are intended for the concert stage. It is the hope of the author that this project can generate more interest in Christopher Caliendo's clarinet repertoire throughout the clarinet community.

Concerto for Piano and Chamber Orchestra was conceived in February of 2013, and conceptually it is my attempt to fuse personal expressions of jazz and classical music into one fully realized statement. It is a three movement work (fast, slow, fast) for 2 fl., 2 ob., 2 cl., bsn., 2 hrn., 2 tpt., tbn., pno., perc., str. (6,4,2,2,1). The work is approximately 27 minutes in duration. The first movement of the Concerto is written in a fluid sonata form. A fugato begins where the second theme would normally appear, and the second theme does not fully appear until near the end of the solo piano section. The result is that the second theme when finally revealed is so reminiscent of the history of jazz and classical synthesis that it does not sound completely new, and in fact is a return of something that was heard before, but only hinted at in this piece. The second movement is a kind of deconstructive set of variations, with a specific theme and harmonic pattern implied throughout the movement. However, the full theme is not disclosed until the final variation. The variations are interrupted by moments of pure rhythmic music, containing harmony made up of major chords with an added fourth, defying resolution, and dissolving each time back into a new variation. The third movement is in rondo form, using rhythmic and harmonic influences from jazz. The percussion plays a substantial role in this movement, acting as a counterpoint to the piano part throughout. This movement and the piece concludes with an extended coda, inspired indirectly by the simple complexities of an improvisational piano solo, building in complexity as the concerto draws to a close.

Bright Summer, a one-movement piece for orchestra, was composed in Arizona, and completed in February 2013. The piece is approximately twelve minutes long. The motivation for writing this piece was the death of my mother the year before, in 2012. The prevailing mood of this work is bright and pleasant, expressing my mother's cheerful personality when she was alive. It also portrays bright summer days which resemble my mother's spirit. Thus, soundscape plays an important role in this work. It depicts summer breeze, rustling sounds of leaves, and, to translate a Korean saying, "high blue skies." This soundscape opens the piece as well as closes it. In the middle section, the fast upbeat themes represent my mother's witty and optimistic personality. The piece also contains the presence of a hymn tune, The Love of God is Greater Far, which informs the motivic content and also functions as the climax of the piece. It was my mother's favorite hymn and we used to sing it together following her conversion to Christianity. The piece contains three main sections, which are held together by transitional material based on the soundscape and metric modulations. Unlike my earlier works, Bright Summer is tonal, with upper tertian harmonies prevailing throughout the piece. However, the opening and closing soundscapes do not have functional harmonies. For example, tertian chords appear and vanish silently, leaving behind some resonant sounds without any harmonic progression. Overall, the whole piece is reminiscent of my mother who lived a beautiful life.

The works of premier Finnish composer Kaija Saariaho demonstrate a fascination with the exploration and expansion of timbral possibilities. This project explores Laconisme de l'aile and NoaNoa, the only two of her works written for solo C-flute. Saariaho has developed a unique compositional style for the flute, characterized by extremes of color which are expressed through extended techniques such as the integration of the voice, with and without text, into the music, the exploration of "noise," the transformation between different timbres, and the use of electronic effects. Laconisme de l'aile (1982) is a dramatic and passionate work filled with lyrical gestures and intriguing timbres with optional electronic effects, and is an excellent introduction to the composer's writing for the flute. NoaNoa (1992) is characteristic of her mature compositional style. Like many of her later works, the electronic aspect of the work is integral to the piece. Saariaho's exploration of the timbral spectrum of the flute has resulted in a complex and unusual style of notation, making these works somewhat inaccessible for performers. Additionally, the technological requirements for NoaNoa make the work both intimidating and impossible to perform without either extensive technical knowledge or consultation with someone who has the necessary technical expertise. Through a detailed performance guide and reference recordings of both works, this project aims to make these two works accessible. All technical specifications are explained and the performance instructions address notation as well execution of all designated effects. Additionally, instructions for the electronic portion of NoaNoa allow flutists to perform the work with minimal assistance.
