This dissertation presents evidence that Béla Bartók created his masterwork, the Sonata for Two Pianos and Percussion (1937), in a very complex period of his life. Since it was a mature piece, Bartók utilized typically "Bartókian" compositional techniques and styles. His ethnomusicological studies were also influential factors in the creation of the Sonata for Two Pianos and Percussion. We can be witness to how different the first draft was to the published version; the minor and major changes are revealed in the draft study of the Sonata for Two Pianos and Percussion 's first movement. These changes allow today's musicians to reconstruct the compositional process. The first movement introduces some interesting uses of sonata form, to be explored in more detail in the analysis. Starting with linear analysis, the basic motives and rhythmic patterns are discussed and supported with Bartók's own explanations. The conclusion of this study has important ramifications for performance: it eases up the pressure on the performers, since problematic passages are analyzed and explained - preparing the players' mentally for the performance. This is music which is hard to play and difficult to analyze. The analysis, combining the results of both theoretical and musicological studies, is intended to help both analysts and performers understand the genesis of the piece and, for performers, to execute the music in the best possible manner.

Although the topoi and elements of what has been described as the “Venerable Style” (V.S.) are found in many places in Mozart’s solo keyboard sonatas, the obsessive juxtaposition of these elements against brilliant, concerted, Empfindsamer Stil, and Sturm und Drang topoi can be shown to define the first and third movements of his minor key piano sonatas K.310 and K.457. This thesis will investigate using the theoretical tools developed by a range of Topic Theory authors such as Ratner (1980,) Allanbrook (1983,) Hatten (2004,) and Monelle (2000, 2006,) a newly developed analytical concept known as topical expansion, and the structural framework provided by Hepokoski and Darcy (2006) to prove that the venerable topoi are not purely referential gestures, but are also vital parts of the structural content of each of the sonatas and their respective single movements. In line with Caplin (2005)’s warning that the venerable and learned styles are some of the only historically developed and generally accepted topoi with formal (structural) ramifications, this thesis will argue that K.310 and K.457’s surface content is built largely upon the application, troping, and expansion of V.S. topoi in the key formal regions given in Hepokoski and Darcy (2006). As a result of comparative analysis, a further topical level of unity and compositional organization will be shown to be present in the works justifying Kinderman (2006) and Irving (2010)’s conception of the works’ stylistic affect as avant-garde and romantic in execution. Additionally, analysis of the works’ strictly controlled topoi will show each work to be in opposition to Allanbrook’s conception of Mozart’s music as a “miniature theater of gestures,” suggesting that their austere affect is programmed at the topical level in addition to their tonal and formal content (Allanbrook 1992, 130).

Research has been conducted on Francis Poulenc and his prominent 20th century sonata for brass instruments. Poulenc and members of the French compositional collaboration known as Les Six have all been subjects of research. Francis Poulenc's Sonata for Horn Trumpet and Trombone is a crucial piece in the development of brass chamber music during the 20th century. As one of the first works written for modern brass instruments, it demonstrates a highly crafted compositional style representative of Poulenc's early period. Research includes background and historical significance of the Sonata, analysis of form and compositional techniques, biographical information on Francis Poulenc and the members of Les Six and a section on implications for the performance of the work. This study is necessary due to the lack of research available for the piece especially considering its relevance to the development of brass chamber music. This study explores the compositional style of Francis Poulenc and his contribution to the brass ensemble repertoire.

The objective of the dissertation is to examine Cyril Scott's musical language as exhibited in his Piano Sonata, Op. 66. Subjects of discussion include Scott's use of form, rhythm, melody, tonality, and harmony. Also included are a biographical sketch of the composer and his philosophical view of modernism. A comparison of the original version and the revised edition of this sonata, as well as references to Cyril Scott's two other piano sonatas are also included during the examination of his harmonic and rhythmic style.

Polystylism in Alfred Schnittke's music has been considered by scholars as a central aspect of his music. Although there are many published analyses of his choral music, symphonies, concerti and violin sonatas, there is no known published research for Schnittke's first cello sonata. Alfred Schnittke grew up in a culturally diverse environment influenced by many different composers and compositional styles under the restrictions of a communist Russian government. These aspects influenced the development of Schnittke's polystylism, characteristically represented by his Cello Sonata (1978). The detailed musical analysis of this sonata in this study serves the purpose to reveal Schnittke's polystylistic tendencies and his use of cyclic elements. These polystylistic elements in the sonata illustrate how Schnittke de-familiarizes listeners from rules commonly accepted as unavoidable and re-familiarizes listeners with the expressive qualities of tonal, twelve-tone and atonal music. Although Schnittke introduces polystylistic materials in de-familiarized contexts in this sonata, this study finds that Schnittke particularly re-familiarizes the audience's musical and stylistic perception through the reappearance of sections, textures and motifs. Abrupt polystylistic conflicts contrast with the repetition of previous materials, thereby forming a combination of traditional styles with features of discontinuity in 20th century music.

The purpose of this study is to identify some of the performance problems associated with contemporary piano music, using the Sonata No. 2 for Piano by Karel Husa (1921 - ) as the basis for the discussion. In so doing, this study identifies Karel Husa as an important contributor to twentieth century piano repertoire. Personal interviews and correspondence with the composer provided biographical, analytical, and stylistic insight for this study. Supplemental information on Karel Husa was obtained from journals, newspaper articles, and dissertations. The first chapter provides biographical information gleaned from the interview, with emphasis on Husa's keyboard compositions and early compositional influences. The second chapter offers a detailed formal analysis of the Sonata No. 2 from the perspective of motivlc development and cyclic unity. The final three chapters focus on twentieth century performance problems as exemplified in Karel Husa's Sonata No. 2 for Piano. In Chapter 3, the discussion of notation provides a general background on notational developments in pitch and rhythm in the twentieth century, with the Sonata illustrating these procedures. The fourth chapter concentrates specifically on Husa's individual rhythmic language. The final chapter is devoted to Husa's coloristic use of the piano, addressing his unique contributions to the tonal and timbral resources of the instrument. Innovations in dynamic gradations, playing inside of the piano, and extensive use of all three pedals are discussed, as well as the special techniques required to achieve these sounds. In all the chapters, musical examples from the Sonata Illustrate the discussion, and reprinted by permission from the publisher. Throughout the dissertation, Karel Husahas provided Invaluable assistance and insight thus offering readers an important link to both the Sonata No. 2 and the composer himself.

American composer George Antheil's Sonata for Trumpet and Piano was written in 1951. This dissertation provides historical and theoretical information that gives insight into the interpretation of this sonata. Reasons why the piece deserves greater attention with respect to the standard twentieth century trumpet literature are also given. Antheil's music was influential in the development of classical music in the first half of the 20th century and, more specifically, contributed to the establishment of an American style of classical music. Composed near the end of his life, this sonata has its roots in this heritage. The understanding of Antheil's history, motivations, and compositional techniques is intended to help bring a performance of this sonata to its full potential.

Sofia Gubaidulina is one of the leading composers in the contemporary music world. Her compositional interests have been stimulated by the exploration of and improvisation with rare folk and ritual instruments, and by a deep-rooted belief in the mystical properties of music. Gubaidulina is the author of orchestral and choral works, compositions for solo instruments, chamber music, as well as electronics music. Gubaidulina's Piano Sonata sums up the composer's thinking within her piano music, and at the same time projects the development of her spiritual vision within other genres that are to come. The analytical approach in this paper is based on the correlation between each of the elements of the musical material (form, rhythm, sound, etc.) and its contextual meaning in terms of musical dramaturgy. Set-theory is applied to the analysis of motivic components of the work. The traditional form is just the basis for the original intonational structure within a modern musical idiom. Varieties of rhythmic patterns, as well as an unconventional sound production, make this work breath with an impetuous power. The examination of the Sonata's musical language and content should give some insight not only into Guabaidulina's piano music, but also into a consequent development of her compositional thinking.

The purpose of this study is to define the French sonatina of the twentieth century, to expose those works which are most suitable for concert performances, and to provide a resource for teachers and performers. Of the seventy-five scores available to the writer, five advanced-level piano sonatinas of the twentieth century were chosen as the best of those by French composers, in attractiveness and compositional craftsmanship: Maurice Ravel's Sonatine (1905), Maurice Emmanuel's Sonatine VI VI(1926), Noel Gallon's Sonatine (1931), Alexandre Tansman's Troisieme Sonatine (1933), and Jean-Michel Damase's Sonatine (1991). The five works were analyzed, with a focus on compositional techniques used to create unity in the work. In comparison to the classical model of the late-eighteenth and early-nineteenth centuries, the French sonatina of the twentieth century exhibits four new features. First, it is more expansive in length and has greater philosophical depth. Second, there is an emphasis on unity at the motivic and thematic levels in which the development of material, based on the techniques discussed, occurs throughout a movement instead of being limited to a "development" section. Third, the formal structures are more flexible, allowing for cyclic quotations and the accommodation of varying styles. Fourth, the advanced technical skills indicate that these compositions are intended not as pedagogical pieces but as concert works. Chapter I introduces the topic, stating the purpose and need of the study. Chapter II presents a brief history of the sonatina, with particular attention given to the sonatina line France, and background information on each of the five composers. Chapters III through VII are each devoted to an analytical discussion of one of the five sonatinas. Conclusions based on the analyses are given in Chapter VIII. Appendices included an annotated listing, by composer, of all French sonatinas which were involved in the research and a selected discography.

This document attempts to present the piano music of Claudio Santoro, a major twentieth century Brazilian composer. In order to illustrate the composer's background, the first chapter addresses briefly the situation of Nationalist music from the beginning of the second decade of this century to the 1940s, when Claudio Santoro came into the Brazilian scene. A general discussion about the Modernismo movement initiated by Mario de Andrade and the opposed views to the later school by the group Música Viva - headed by Hans Joachim Koellreuter - illustrates the politics and sociology in the music scene in Brazil during the first decades of the twentieth century. A biography, focusing mostly in a personal account by the composer, serves to illustrate Santoro's family background, environment, education and struggles to develop into a first class musician. The compilation of Santoro's piano music and an overview of its characteristics, introduces pianists to this Brazilian composer, whose body of works include mostly orchestral music. Although not a pianist himself, he composed several valuable piano works worthy of the repertoire. The Fourth Sonata represents one of Santoro's most popular piano works. The analysis of this work focuses on clarifying how the structure may be organized and how the chromatic idiom supports Santoro's deceptive tonal goals.
