This project presents eight harpsichord sonatas, 3, 5, 10, 12, 13, 18, 19, and 21, by Sebastián de Albero (1722-1756), arranged for the classical guitar. These pieces were chosen because of the success of other eighteenth-century Iberian harpsichord music that has been arranged for guitar, including works by composers such as Domenico Scarlatti, Carlos Seixas, and Antonio Soler. The popularity and enjoyment of Scarlatti's harpsichord sonatas on the guitar today was the inspiration for this project.

Historically, guitarists have used arrangements as a means to expand the guitar's repertoire. The late eighteenth century, especially, was a time in which the instrument was undergoing significant changes from being a five-course instrument into becoming the standard six single string instrument of today. Also, composer/guitarists at that time were beginning to abandon tablature in favor of modern staff notation. Because of these changes, the amount of music originally written for the guitar from this period that is suitable to be played on a modern instrument is limited.

I chose to focus on eight selected sonatas from Sebastián Albero's Treinta Sonatas para Clavicordio because of the influence of Domenico Scarlatti's harpsichord arrangements for solo guitar. It is intriguing to note that Albero and Scarlatti both held positions at the Spanish Royal Chapel for a number of years and, in this capacity, may have influenced one another in their musical compositions and style. Certain similarities are documented in this paper.

Since Scarlatti's music has been successfully arranged, and is popular to play on modern guitar, it is hoped that these sonatas by Albero may enjoy similar success.

The C.G. Conn instrument manufacturing company is known as one of the most successful and innovative band instrument manufacturers in the history of the United States. Many of C.G. Conn's instrument product lines have undergone significant changes throughout the company's history, especially in the brass family. The C.G. Conn tuba product lines are no exception to this company's extraordinary success, and have been significantly redesigned since the company began manufacturing these instruments in circa 1880. This research project investigates the tuba product lines that C.G. Conn manufactured between 1880 and 1940. C.G. Conn designed six different tuba product lines during this timeframe, including an unnamed tuba product line with Stölzel valves, the Wonder Valve line, the New American line, the Wonder Model line, the 20-J, and the 22-J instrumental product lines. These tuba product lines have been investigated using extant publications and patent information because the majority of C.G. Conn's internal records prior to 1970 have been lost. In addition to investigating each of C.G. Conn's early tuba product lines, this project also explores the particularly anomalous design in the top-action valve apparatus of the Conn Wonder Model tuba product line. This anomalous design was implemented in the all of C.G. Conn's top-action tuba and tuba-like product lines from circa 1890-1940. This author's measurements of period instruments and analysis of data taken from these measurements indicates that this anomalous top-action valve apparatus design utilized interchangeable parts with other front-action C.G. Conn tuba product lines.

Preservation Symphony is a short, multi-movement, orchestral composition that explores the versatility of the [016] pitch class set as the dominant unifying force of this cyclical work. The composition is scored for Piccolo, two Flutes, two Oboes, English Horn, two Clarinets, Bass Clarinet, full complement of Brass, Timpani, two Percussionists, and Strings. Movement one is in sonata form; the [016] set is used in structuring its overall formal scheme. The primary focus of the movement is on the tritone [0 6] as a replacement for the traditional tonic and dominant polarity. The movement features a driving force that alternates between pulse subdivisions of even sixteenth notes and sixteenth-note triplets. Movement two is in simple binary form with a central tonality of A. An English Horn solo functions as both the opening of the movement and a transition from the tonality of movement one (F) into the new tonal center of A. The unifying pitch class set [016] is used in this movement in a Phrygian context. Movement two has a contemplative and dark tone, which is in stark contrast to the outer movements. Movement three has a lighter, upbeat nature. The movement is in rondo form with its main theme written in a folk-like character. This movement returns to F as the central tonality, completing the overall tonal plan of the work. As in movement one, it explores the tritone polarity of F and B. The movement also revisits the chromatic mediant relationship found in the middle of movement two in the oboes. The pitch class set is now used in the context of a Lydian-Mixolydian (or acoustic) scale, from which both the central and secondary themes of the rondo are derived.

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.

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.
