Summer Sprite for Orchestra

Summer Sprite for Orchestra was completed in December, 2004. The piece originated from a singular encounter with little angels at Chang-Kyung Palace, which is the oldest and the most beautiful palace in Korea, and where the kings of the Chosun Dynasty (1393-1897) lived. This encounter was in the summer of 2002. I certainly could not prove that those angels I met were real. Possibly they were the reflection of drops of water after a sudden shower on that summer day. However, I definitely remember that short, unforgettable, and mysterious moment and the angels' beautiful dance-like celebration. Summer Sprite is based on these special memories and the encounter with the little angels that summer. Summer Sprite consists of 3 movements: "Greeting," "Encounter," and "Celebration." These follow the course of my encounter with the little angels. In Summer Sprite, I wished to describe the image of the angels as well as the progression of greeting, encounter, and celebration with them. The moods that follow in Summer Sprite are by turns lyrical, poetic, fantastic, mysterious, and dream-like. In each movement, I describe the meeting of angels and composer through the use of the soloists -- violin (sometimes viola) and cello. As suggested by the subtitle of the first movement, "Greeting" portrays the moment when a surprised I met the angels. It begins with tam-tam, marimba, harp, and piano and sets a mysterious and dark mood. The second movement, "Encounter," is shorter than the first movement. This movement provides a more tranquil mood as well as more unique timbres resulting from the use of mutes and special instruments (English horn, harp, crotales, suspended cymbal, and celesta). The delicate expression of the percussion is particularly important in establishing the static mood of this movement . The last movement, °?Celebration,°± is bright and energetic. It is also the longest. Here, I require the most delicate changes of dynamics and tempo, the most vigorous harmonies, and the fastest rhythmic figures, as well as the most independent, lyrical, and poetic melodies. For bright orchestral tone color, I used various kinds of percussion such as timpani, xylophone, marimba, vibraphone, cymbals, side drum, tambourine, triangle, and bass drum. This last movement is divided rondo-like into five sections: The first (mm.1-3), second (mm.4 - rehearsal number 1), third (rehearsal numbers 2-4), fourth (rehearsal numbers 5-7), and fifth, (rehearsal numbers 8 -18). To sum up, Summer Sprite describes an unforgettable and mysterious moment in a my life. My intention was to portray this through a concerto-like framework. A model for this would be Brahms°Ø °?Double Concerto°± in A minor, op.102, in which the solo cello stands for my angel and the solo violin (sometimes solo viola) for me.

VISION OF EQUINOX FOR ORCHESTRA

The artistic play of light seen on a pyramid in some Mayan ruins located in Cancun, Mexico provided the inspiration for Vision of Equinox. On both the spring and autumn equinox days, the sunlight projected on the pyramid forms a shape which looks like a serpent moving on the stairway of the pyramid. Vision of Equinox was composed with an image of light as the model for the artistic transfiguration of sound. The light image of sound changes its shape in each stage of the piece, using the orchestra in different ways - sometimes like a chamber ensemble, sometimes like one big instrument. The image of light casting on a pyramid is expressed by descending melodic lines that can be heard several times in the piece. At the final climax of the work, a complete and embodied artistic figure is formed and stated, expressing the appearance of the Mayan god Quetzalcoatl, the serpent, in my own imagination. The light and shadow which comprise this pyramid art are treated as two contrasting elements in my composition and become the two main motives in this piece. To express these two contrasting elements, I picked the numbers "5" and "2," and used them as "key numbers" in this piece. As a result, the intervals of a fifth and a second (sometimes inverted as a seventh) are the two main intervals used in the structure. The interval of a fifth was taken into account for the construction of the pyramid, which has five points of contact. The interval of a second was selected as a contrasting sonority to the fifth. Further, the numbers "5" and "2" are used as the number of notes which form the main motives in this piece; quintuplets are used throughout this piece, and the short motive made by two sixteenth notes is used as one of the main motives in this piece. Moreover, the shape of the pyramid provided a concept of symmetry, which is expressed by the setting of a central point of the music (pitch center) as well as the use of retrograde and inversion in this piece.

Doubt, for narrator and orchestra

Doubt is a single-movement composition of roughly twelve minutes for narrator and orchestra (woodwinds, horns, and trumpets in pairs, timpani, percussion, strings). The piece explores the controversial issue of capital punishment. The text was compiled from resources found on the websites of Death Penalty Information Center (http://www.deathpenaltyinfo.org) and Anti-Death Penalty Information (http://www.antideathpenalty.org), as well as excerpts from the Bible. Doubt was conceived of as a dramatic work in which a narrator recites factual information in a direct and unemotional manner and the orchestra provides a response to the mixed emotions elicited by the text. The list of dates and case summaries presented in the middle section of the piece seemed most powerful and effective when recited in a natural speaking voice, which is why I chose not to set the text as song. Also, I chose the orchestral medium rather than a chamber setting because the nature of the topic demanded a larger range of colors and combinations, as well as a louder, fuller sound. Much of the music was composed while deciding which texts to include. Thus the music influenced the choice of text as much as the text suggested the musical setting. The four formal divisions of the piece are delineated primarily by the text. The first section is an orchestral introduction representing various emotional perspectives suggested by the texts. The narrator begins the second section with a Biblical verse over sparse orchestration. The third and main section of the piece begins with a new melody in the low strings that is closely related to the harmonic organization of the piece. The narrator lists dates of convictions, executions, exonerations and facts related to doubtful cases. The third section and the narration conclude with another brief passage from the Bible. The fourth section is a dramatic orchestral coda, bringing back the opening harmonies of juxtaposed perfect fifths. The final chord is full of tension and discord, reflecting the oppositions inherent in the topic of capital punishment: life vs. death, sympathy vs. reproach, pain vs. hope, but above all, doubt about guilt vs. innocence.

The Interloping Beguiler: for Bass Clarinet and Orchestra

The Interloping Beguiler is an nineteen-minute concerto in four movements for bass clarinet solo and orchestra. The title refers to the role of the solo instrument, which continually thrusts itself into the affairs of the orchestra, deceiving and diverting the members of the orchestra away from their task of performing a "serious" orchestral composition. The bass clarinet portrays a comical, cartoon-like character whose awkward, and sometimes goofy, interjections cause chaos. Attempts are made by various members of the orchestra, especially the horns, to regain control of the work, but the bass clarinet always succeeds in its distracting antics. By the final movement of the composition, the bass clarinet has propelled the work into a cartoon-like landscape of quickly changing textures, dissonant intervals, and overlapping themes. The first movement, Introduction, sets the serious tone of the music to follow, or so it would seem. The entrance of the bass clarinet immediately changes this texture with its out-of-rhythm alternations between high and low pitches. This gesture provides a glimpse into the personality of the bass clarinet, an instrument here to mislead the members of the orchestra. Deception truly begins in the second movement, The Interloping Initiates. The bass clarinet starts the movement with a driving theme and is immediately supported by the orchestra. As the movement progresses, the bass clarinet quickly begins altering the theme, making it more playful and cartoonish. A struggle ensues between the horns and the bass clarinet, with the bass clarinet catapulting the piece into a latin-inspired section. The struggle continues through to the end of the movement. The third movement, Calm, is exactly what the title suggests. A sectional form distinguishes this movement from the second movement. Throughout Calm, the bass clarinet behaves with decorum, except for very large melodic leaps. The seed of anarchy planted by the bass clarinet in the second movement comes to fruition in the final movement, The Beguiling Builds. Here, the bass clarinet sends the work into chaos with sections recalling Looney Tunes cartoons, Hollywood western music, and children's folk songs.

All This the World Well Knows: a symphonic cantata in Sonnets and Proverbs for mixed chorus, four solo voices, and orchestra

All This the World Well Knows is a 30-minute symphonic cantata for mixed chorus, four solo voices (soprano, mezzo-soprano, tenor, and baritone), and orchestra. The libretto, adapted by the composer, weaves together texts from Shakespeare's Dark Lady sonnets and from the King James Bible's book of Proverbs in a loose narrative of love, betrayal, and reconciliation. The composition's pitch material includes microtonality that arises from the just intonation of sonorities derived from the harmonic series. In passages in which the solo voices express this microtonality, they are amplified in order to allow precise, non vibrato intonation. The modest size of the orchestra, which includes pairs of winds and only two percussionists, makes the composition practical for a wide range of performing groups.

TRADITION AND INNOVATION: ANALYSIS AND PERFORMANCE OF SELECTED COMPOSITIONS FOR VIOLONCELLO BY HEITOR VILLA-LOBOS

Brazilian composer Heitor Villa-Lobos (1887-1959) began his musical career as a cellist. When he was only twelve years old, it became imperativeupon the sudden and untimely death of his fatherthat the young Villa-Lobos earn money as a cellist to provide financial support for his mother and sisters. Villa-Lobos's intimate relationship with the cello eventually inspired him to compose great music for this instrument. This dissertation explores both the diversity of compositional technique and the evolution of style found in the music for cello written by Villa-Lobos. The project consists of two recorded recital performances and a written document exploring and analyzing those pieces. In the study of the music of Villa-Lobos, it is of great interest to consider the music's traditional European elements in combination (or even juxtaposition) with its imaginative and sometimes wildly innovative Brazilian character. His early works were greatly influenced by European Romantic composers such as Robert Schumann, Frédéric Chopin, and the virtuoso cellist/composer David Popper (whom Villa-Lobos idolized). Later, Villa-Lobos flourished in a newfound compositional independence and moved away from Euro-romanticism and toward the folk music of his Brazilian homeland. It is intriguing to experience this transition through an exploration of his cello compositions. The works examined and performed in this dissertation project are chosen from among the extensive number of Villa-Lobos's cello compositions and are his most important works for cello with piano, cello with another instrument, and cello with orchestra. The chosen works demonstrate the evolving range and combination of characteristic elements found in Villa-Lobos's compositional repertoire.

ION, OPERA IN SEVEN SCENES, BASED ON EURIPIDES ORIGINAL PLAY

The opera ION serves as my Doctoral Dissertation at the University of Maryland School of Music. The librettist of the opera is Nick Olcott, Opera Assistant Director at the University. My interest in this little-known play of Euripides began with my work with Professor Lillian Doherty of the University's Classics Department. Since I am fluent in Greek, I was able to read the play in original, becoming aware of nuances of meaning absent in the standard English translations. Professor Leon Major, Artistic Director of the University's Opera Studio, was enthusiastic about the choice of this play as the basis for an opera, and has been very generous of his time in showing me what must be done to turn a play into an opera. ION is my first complete stage work for voices and constitutes an ambitious project. The opera is scored for a small chamber orchestra, consisting of Saxophone, Percussion (many types), Piano, a Small Chorus of six singers, as well as five Soloists. An orchestra of this size is adequate for the plot, and also provides support for various new vocal techniques, alternating between singing and speaking, as well as traditional arias. In ION, I incorporate Greek folk elements, which I know first-hand from my Balkan background, as well as contemporary techniques which I have absorbed during my graduate work at Boston University and the University of Maryland. Euripides' ION has fascinated me for two reasons in particular: its connection with founding myth of Athens, and the suggestiveness of its plot, which turns on the relationship of parents to children. In my interpretation, the leading character Ion is seen as emblematic for today's teenagers. Using the setting of the classic play, I hope to create a modern transformation of a myth, not to simply retell it. To this end, hopefully a new opera form will rise, as valid for our times as Verdi and Wagner were for theirs.

NEGLECTED CELLO REPERTOIRE OF TWENTIETH CENTURY ENGLISH COMPOSERS

In the Twentieth Century, the proliferation of cellists and the exceptional development of cello techniques, combined with composers' acceptance of the challenges by these developments, led many British composers to contribute to the enrichment of the cello concert repertoire. A great number of compositions written for the cello in the Twentieth Century England have been long neglected. In comparison with their other works in the genres of concerto, symphony, and opera, works for cello by prominent Twentieth Century English composers Elgar, Walton, and Britten are relatively unknown, except for Elgar's cello concerto. There are also many lesser-known composers like Delius, Bax, Bridge, and Clarke, who flourished in the fmt half of the century, but eventually became disregarded. Some reasons for this neglect may be as follows: the reluctant attitude toward new trends in the English musical establishment around the turn of the century; a lack of readily available editions of these composers' compositions; an over-abundance of fine composers at one time; and lastly, an overly individualistic approach to the music restricting a general public appreciation and recognition. Encountering a recording of the Walton cello concerto prompted me to further study the neglected Twentieth Century English cello repertoire. Many works of the above-mentioned composers still have not been fully valued in the cello repertoire. For this reason, the purpose of this project was to inspire cellists to learn and broaden as well as to appreciate the beauty of the Twentieth Century cello literature. As part of the doctoral performance project, three recitals featuring the works by six English composers were performed. My collaborator in all three recitals was pianist Eunae KO. The fmt recital included the Sonata for cello and piano by Frank Bridge and the Concerto by William Walton. The second recital was comprised of relatively unknown cello works: Sonatina in D major by Arnold Bax, Romance by Frederick Delius, and the Sonata Op. 40 by Rebecca Clarke. The third recital consisted of Folk-Tale by Arnold Bax and the Symphony for Cello and Orchestra Op. 68 by Benjamin Britten.

Selected Solo Music for Saxophone by United States Composers: 1975-2005

This dissertation project identifies important works for solo saxophone by United States composers between 1975 and 2005. The quality, variety, expressiveness, and difficulty of the solo saxophone repertoire during these thirty years is remarkable and remedies, to some extent, the fact that the saxophone had been a largely neglected instrument in the realm of classical music. In twentieth-century music, including Jazz, the saxophone developed, nevertheless, a unique and significant voice as is evident in the saxophone repertoire that expands immensely in many instrumental settings, including the orchestra, solo works, and a wide variety of chamber ensembles. Historically, the saxophone in the United States first found its niche in Vaudeville, military bands, and jazz ensembles, while in Europe composers such as Debussy, D'Indy, Schmitt, Ibert, Glazounov, Heiden, and Desenclos recognized the potential of the instrument and wrote for it. The saxophone is well suited to the intimacy and unique timbral explorations of the solo literature, but only by the middle twentieth century did the repertoire allow the instrument to flourish into a virtuosic and expressive voice presented by successive generations of performers – Marcel Mule, Sigurd Rascher, Cecil Leeson, Jean-Marie Londeix, Fred Hemke, Eugene Rousseau, and Donald Sinta. The very high artistic level of theses soloists was inspiring and dozens of new compositions were commissioned. Through the 1960’s American composers such as Paul Creston, Leslie Bassett, Henry Cowell, Alec Wilder, and others produced eminent works for the saxophone, to be followed by an enormous output of quality compositions between 1975 and 2005. The works chosen for performance were selected from thousands of compositions between 1975 and 2005 researched for this project. The three recital dates were: April 6, 2005, in Gildenhorn Recital Hall, December 4, 2005, in Ulrich Recital Hall, and April 15, 2006, in Gildenhorn Recital Hall. Recordings of these recitals may be obtained in person or online from the Michelle Smith Performing Arts Library of the University of Maryland, College Park.

Three Voices in the Wilderness: Foote, Bloch, and Korngold in the Early Twentieth-Century America

Barbara Hanning points out in her book Concise History of Western Music, that "Twentieth-century American music was in large measure an extension of European music" (Hanning 1998, 515). My dissertation/perforrnance project features cello works written by three contemporary composers who lived in America but were connected to the European heritage in different ways; each contributed significantly to the development of American classical concert life, music education, and even popular culture. Programs of my performances are intended to illustrate their unique compositional styles. The first recital consists of five cello compositions of Massachusetts-born Arthur Foote (1853 - 1937): Drei Stucke fur Pianoforte und Violoncello, Op. 1; Scherzo, Op.22; Romanza, Op.33; Aubade, Op.77; and Sonata for Violoncello and Piano, Op.78. Foote was influenced by the German-trained John Knowles Paine at Harvard University; he composed music famous for its extensive chromaticism in both harmony and melodic line, and for clearly-defined formal structure. The second recital explores the music of Swiss-American composer Ernest Bloch (1880-1959): a short Meditation Hebraique, a Suite No. I for Violoncello Solo and the famous rhapsody Schelomo. Born in Geneva, Switzerland, and settling in the United States in 1916, Bloch is a composer deeply influenced by the European late-Romantic tradition and is also well-known for employing "Hebraic" elements into his works. The final performance comprises two other of Bloch's cello works and one cello concerto by the Austrian-American composer, Erich Wolfgang Korngold (1897- 1957). Bloch's Voice in the Wilderness is a symphonic poem for orchestra and cello (accompanied by piano in this performance), consisting of six movements performed without pause. His Suite No.3 for Cello Solo is shorter and has a simpler style than the first Suite. Korngold was recognized as a child prodigy in his native Austria. After a Nazi-induced exile, he immigrated to America and became a film music composer in Hollywood. The Cello Concerto was used in the movie "Deception" (1 946), for which Korngold provided the film score. The impassioned harmonic language and lavish melodic lines inherited from the high-romanticism make this work one of comparative discordant beauty among other compositions of his time.

The Scherzo in Selected Works for Piano

This performance project will cover performing issues in terms of technique in the scherzo. The Dictionary of Musical Terms defines technique as "the system of creating music, the musical slull to show personality by controlling tones that is not an abstract theory but a practical ability in composition or performance." My project focuses on techniques in fast tempos, specifically those found in the scherzo form and in concertos containing a scherzo character. The term scherzo has varied in its meaning and form throughout history. In the Baroque period, a scherzo was a work of light vocal or instrumental character. In the Classical period, scherzo still meant light in style, but it also indicated a quick tempo, often in 2/4 time. The scherzo was usually a single movement in a suite or multi-movement work. Like the minuet form, the scherzo contained a contrasting trio section. The scherzo was also standard in Romantic and post-Romantic symphonies and related genres. Because of the high degree of subjectivity in Romantic music, genres that stressed emotional content over abstract form developed rapidly. Some composers even wrote one-movement pieces entitled scherzo. These pieces became very important because they usually expressed a particular character or mood. The objective of my dissertation project is to research scherzo-like concertos, scherzo as single movements in larger forms, and scherzo as independent works. My first recital will consist of two concertos with a scherzo-like character. These are Mozart's Piano Concerto No. 9 i ?nl Major; K. 271 and Ravel's Piano Concerto in G Major. I will perform these works in December 2002 with a second piano. In addition, I will perform the Ravel with an orchestra in 2003. My second recital will consist of two parts. The fxst half presents multi-movement works with scherzo movements. The pieces are Haydn's Piano Sonata No. 3 in F Majol; Hob. WI/9, Beethoven's Piano Sonata No. 10 in G Major; Op. 14, No. 2. The second half presents independent four scherzi by Chopin. The final program will also include multi-movement works containing scherzo and independent scherzo. These are Prokofiev's Piano Sonata No. 2 in D minor, Op. 14, Grieg Lyric Pieces Op. 54, Schubert Zwei Scherzi D. 593 and Copland Scherzo humoristique; Le Chat et la Souris (The Cat and the Mouse).

ELGAR AND MART&: THE CELLO WORKS AND MUSICAL CHARACTERISTICS OF TWO REMARKABLE, SELF-TAUGHT, NATIONALISTIC COMPOSERS

The British Edward Elgar and Czech Bohuslav MartinB were two of the most prominent Nationalistic composers of their respective countries during the late nineteenth and early twentieth centuries. Their musical patriotism incorporates the unique paths of their lives as socially isolated and self-taught composers as expressed their outstanding Nationalistic compositions produced through the period of history encompassing the two World Wars.In the first chapter of this dissertation, a brief biography of Elgar is presented and the essential aspects of his formative years influencing him to become a self-taught musician are discussed. The second chapter demonstrates Elgar's musical characteristics through the study of a selection of his masterpieces. In the third chapter, a brief biography of Martinti is presented along with a history of his musical development, characterized by his social isolation during four different periods of his life-his residences in PoliCka, Prague, Paris, and then in the United States. The fourth chapter considers MartinB's musical characteristics as revealed through the study of a selection of his greatest works. In support of this doctoral project, I performed two recitals of cello works by Elgar and Martini3 at the University of Maryland, College Park. The first recital, accompanied by Susan Slingland and Hiroko Yamazaki, included three of Martini3's works, Sonata No. 2 for Cello and Piano (1941); Variations on a Theme of Rossini for Cello and Piano (1 942); and Sonata No. 3 for Cello and Piano (1952). The second recital, accompanied by Wonyoung Chang and Naoko Takao, presented Martini3's Sonata No. 1 for Cello and Piano (1939) and Elgar's Concerto for Cello and Orchestra Op. 85 in E minor (1 919).

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.

A GOLDEN AGE: FRENCH AND SPANISH CELLO MUSIC FROM SAINT-SAENS TO CASSADO

Motivated by both the delicacy of French music, such as La Mer by Claude Debussy, and the exotic atmosphere of Spanish music, such as Zigeunerweisen by Pablo Sarasate, I decided to investigate the characteristics of French and Spanish cello music from Camille Saint-Saens to Gaspar Cassad6. French cello music flourished from the end ofthel9th to the middle of the 20th century because of the innovation of many unprecedented techniques and experimentation with a variety of sonorities. The Spanish were heavily influenced by the French due to the geographical connection. Cello virtuosi like Auguste Tolbecque, August Franchomme, Pierre Fournier, and Paul Tortelier inspired composers of their day, creating a "golden age" of cello music. This dissertation consisted of three recitals in Gildenhom Recital Hall. The first recital was held on May lOth, 2007 at 5:30pm with pianist David Ballena. The second recital was held on October 14th, 2007 at 2pm with collaborators Minna Han, piano and Jenny Wu, violin. The third recital was held on March 301 2008 at 5:30 with pianist Naoko Takao. Here is the program of the recitals: The first recital: Gabriel Faure(1856-1924): Sonate pour Violoncello et Piano Op.109(1917) Gaspar Cassad6 (1897-1966): Suite per Violoncello Solo (1926) Claude Debussy (1862-1918): Sonate pour Violoncelle et Piano (1915) The second recital: Manuel de Falla (1876-1946): Melodia (1897), Romanza (1898) Camille Saint-Saens (1835-1921): Concerto for Cello and Orchestra No.1 in A minor Op.33 (1873) Maurice Ravel (1875-1973): Sonata for Violin and Cello (1920-22) The third recital: Pablo Casals (1876-1973): Song of the Birds (1925) Edouard Lalo (1823-1892): Concerto for Cello and Orchestra in D Minor (1877) Franscis Poulenc (1899-1963): Sonata for Cello and Piano Op.l43(1940-48)

PIANIST-COMPOSERS WHOSE WORKS INCLUDE PIANISTIC INNOVATIONS

Throughout the piano’s history, certain composers have created innovations in the areas of virtuosity and sonority. These innovations came not only from the composers’ imagination, but also from the development of instruments and changes in musical style from one period to another. To investigate what kinds of innovations these pianist composers made, I divided them into technique and sound from Mozart to Cowell. I chose two-piano music (Sonata in D major, K.448 by Mozart and Rachmaninoff’s Second Suite) to demonstrate their experiments with varieties of textures and sonorities, using different registers of the two pianos orchestrally. En Blanc et noir by Debussy shows this composer’s deep interest and originality in piano sonorities. For solo piano music, Beethoven’s Piano Sonata Op.53 shows extensive technical invention. His use of long pedal effects shows a pianistic possibility not explored by Mozart. Hummel’s Piano Sonata in D major represents orchestral devices as well as pianistic techniques showing recent developments in the instrument. Chopin’s Ballade No.3 and Scherzo No.3 show virtuosic moments and also the expanded range of the keyboard. His Nocturne Op.27, no.2, with its sonorities resulting from the combination of pedal, and widespread accompaniments derived from Alberti bass figures, is a perfect example of Chopin’s characteristic sound-world. “Vallée d’Obermann” by Liszt uses many virtuosic techniques as well as the extreme wide ranges of keyboard in both hands to create dramatic contrasts of texture. Debussy’s etude, “Pour les Sonorités opposés” is probably the first etude designed for sonority rather than for keyboard virtuosity. Albeniz’s “Evocación” and “Triana” show Spanish atmosphere. Prokofiev’s Sonata no.3 shows frequent motoric driving elements that demand percussive virtuosity. Cowell’s piano music is some of the earliest to explore the sonorities of tone clusters and playing on the strings. This performance dissertation consists of three recitals performed in the Orchestra Room, Leah Smith Hall, and Gildenhorn Recital Hall at the University of Maryland, College Park. These recitals are documented on compact disc recordings that are housed within the University of Maryland Library System.
