This dissertation consists of four programs: one lecture- recital, two recitals for piano solo, and one (the Schubert program) in combination with other instruments. The repertoire of the complete series of concerts was chosen with the intention of demonstrating the ability of the performer to project music of various types and composed in different periods.

Inasmuch as this investigator can determine, no major study has been done concerning music's relation to the "isms" selected for this discussion. The contemporary interest in the movements themselves has been so widespread that the documentation of them, in scattered accounts, is enormous. It is disappointing that these records provide little or no information about the musical aspects of the movements; the graphic and literary accounts, on the other hand, have been accorded generous treatments. Since futurism, cubism, and surrealism, in their origins, were oriented toward the visual and literary arts, it is not surprising that these two aspects would receive the greatest amount of attention. The meager attention to music and the distortion of its role in the movements, as has largely been the case, has created an artistic imbalance, This writer's efforts have been directed toward an exhaustive search for factors which have, in some way or other, linked music with these movements. Musical futurism has been the easiest to identify, although its underlying theories are not always clear, since the futurists, in explaining their theories, were not always convincing, perhaps even to themselves. This writer's main attempt has been to interpret ideas that were frequently vague and …

Computers are used in the music field for generation of sound, for composing music, for analysis of music, and for musicological applications, such as cataloguing a bibliography of music literature. These areas are relatively new aspects of computer usage, and research is being conducted to stay abreast of current technological advancements. Avant-garde composers are challenged by new advances in music. Computer-generated music is one of the new trends, but the composer is usually limited in the use of the medium for two reasons: there are no computers to which he may have access, and/or there is not enough knowledge about computer-generated music. The composer sometimes feels that he must have vast knowledge of the computer before he can attempt to use it in musical composition; however, a limited amount of investigation of computer-generated music has shown that methods can be codified to the point where great technical knowledge is not required of the composer.

Sonata in A major, Opus 120, was written by Franz Schubert in 1819. The sonata was chosen for this study because of its proximity to the middle of the span of time in which Schubert wrote his piano sonatas. His first piano sonata was written in 1815 and the last in 1828. Since no sonatas were written in either 1821 or 1822, the years in the middle of this span, the sonata written in 1819 was chosen.

The English horn has a background of historical confusion because the instrument was built in many different shapes and was given a new name for each change of form.

The compositions to be considered in this study have been divided into three periods, corresponding with certain times in the life of Alfredo Casella. There is enough consistency of style in the compositions of each period to justify this division. The first period, characterized by lyricism and virtuosity, includes the works written in Paris after Casella left the Paris Conservatory. The second period, with its chromaticism and dissonance, comprises his output during the first years after his return to Italy. The third period begins with the close of World War I. In this period Casella returns to a classic style which is firmly embedded in an extended tonal system. The compositions of this period combine various ideas and styles gathered through the years and blend them into works marked by maturity, sincerity, and originality.

The twentieth century has witnessed a renaissance in the composition of choral music. Not since the Baroque, has choral writing held the prominent position with composers that it has today. At the same time, English composers have regained a stature and influence they have not held since the time of Purcell. It was not until the time of Edward Elgar, Gustave Holst, and Ralph Vaughn-Williams that English music began to recover from the decline of the nineteenth century. Benjamin Britten has played a large role in both the choral renaissance and the recovery of English music.

This study examines what makes a keyed brass instrument, early keyed brass instruments, and keyed brass instruments of today. Focuses on the Cornett, the Serpent, the Basshorn and Russian Bassoon, the Ophicleide, the Horn, the Keyed Trumpet, and the Keyed Bugle.

The real importance of the twelve-tone system would seem to lie in its structural possibilities. It combines the inherent potentialities of the theme of a movement in sonata form with those of the theme of a fugue and of variations. It creates a coherent texture throughout the single movements and the work as a whole. It is needless to say that this kind of coherence can also be achieved in serial compositions, that is, in movements in which not the full row of twelve tones, but only seven or eight or nine tones form the basic row.

Born April 2, 1873, on the estate of Oneg in the province of Novgorod, Russia, Sergei Vassilyvitch Rachmaninoff was the fifth of the six children of Vassili and Lyoubov Boutakova Rachmaninoff. Rachmaninoff's aristocratic descent was traced to the Hospodars Dragosh, rulers of the realm of Molday from the fourteenth to the sixteenth century. One of the daughters from this family had married a son of the Grand Duke Ivan III of Moscow. The son's nephew was named Rachmanin, and from this source the family name originated.1 Rachmaninoff's mother was the daughter of a general, head of Araktcheyev Military College in Novgorod and the owner of a number of estates in the district. It was with a dowry of five of these estates that Lyoubov Boutakova married Vassili Rachmaninoff, and on one of these estates, Oneg, the couple settled down to married life.

The Piano Fantasy will be compared to Aaron Copland's other major piano works, the Piano Variations and Piano Sonata, to determine if he has retained his basic stylistic features, although he has employed serial principles more extensively in the piano fantasy than in the other two works and has passed through two different style periods, the "Abstract" (1929-1935) and the American "Folksong" (1934-1955).

Traditions in orchestration can be described by relating the practices of most of the important composers of a particular time. This was done with great success by two composers of the nineteenth century, Hector Berlioz and Nicolai Rimsky-Korsakov, in their books on orchestration. These texts are the basis for the traditional uses of brass instruments appearing in the chapter.

Definitions of the trumpet, although disagreeing in certain details, generally concur in a fundamental precept: that the tube of the trumpet is cylindrical for the greater part of its length while flaring into a bell at its end. This study outlines the history of the slide trumpet in England.

The two basic needs which motivated this study were instructional material and instruments. By investigating these problems the writer hopes to improve not only his own techniques of teaching, but to present a useful source of information concerning the tuba. Analysis of the problem statement led to subordinate questions, or sub-problems, which may be stated as follows: 1. What do the authorities consider to be the desirable physical and mental characteristics in the tuba player? 2. How do the authorities teach the specific techniques of tuba performance. 3. What are the authorities' opinions concerning tubas and tuba mouthpieces? 4. What are the authorities' recommendations concerning instructional materials for tuba students?

The purpose of this study is to trace the invention and development of a greatly abused instrument, the saxophone, and its use in the symphony orchestra. The first chapter concerns the instrument's invention and acceptance. The second chapter discusses physical characteristics of the saxophone. The third chapter deals with the particular methods of using the saxophone in orchestral literature by various composers, from its use in the nineteenth century through the present. An appendix provides a comprehensive listing of orchestral literature in which the saxophone is utilized.

It is the purpose of this thesis to present a study of music written for the clarinet during the period from 1600 to 1800. The first part is a history of the clarinet showing the stages of development of the instrument from its early predecessors to its present form. Part one also explains the acoustics of the clarinet and its actual invention. The second part deals with composers and their music for the clarinet. No attempt is made to include all music written for the instrument during the prescribed period; rather, the writer's intention is to include chiefly those works by composers whose musics has proven to be outstanding in clarinet literature or interesting historically. The order in which the works themselves are taken up is chronological, by composers, with comment on their styles as to form, harmonic content, melodic content, rhythmic content, problems in phrasing, or any other general technical problem. All of these elements are illustrated with examples taken from the music.

Since the time of Johann Sebastian Bach many musical compositions have been written on the letters of his last name. In German musical notation, these letters are the equivalents of out B flat, A, C, and B natural. This study traces the use of this motive in works written for the organ throughout the past two centuries. The discussion in these chapters has been an attempt to illustrate the use of the motive B A C H in organ compositions from before the time of Bach up to the present. Time limitations required that this study limit itself to those works appearing in generally available editions.

This study examines the development and creation of the clarinet in the seventeenth and eighteenth century, and the start of their use as a solo instrument in the eighteenth century. This explores Mozart's utilization and development for the clarinet to other various composers and their contributions.

In this study, the Anton Webern's music is considered in two groups: that which was written before Webern adopted the twelve-tone technique, Opp 1-16, and that written in the twelve-tone technique, Opp. 17-31. This division is not intended to represent an attempt at periodization of Webern's music, for the changes of style in Op. 17 are not that significant. But the fact that Webern employed the twelve-tone technique in all the works he wrote after Op. 16 makes this a natural point of division for a study of this sort. Besides the music of Webern, two peripheral areas are included in this study. No attempt has been made at an exhaustive biography of Webern, but facts relative to his life, and impressions about the person are presented. Also, to create a proper perspective for the study of Webern's which existed during the time that Webern lived and composed, is presented.

In this thesis, Ned Rorem's Poems of Love and the Rain is analyzed, with conclusions being drawn in the sphere of musico-textual relationships within individual songs.

A comprehensive study of all nineteenth-century New Orleans composers is far beyond the scope of this paper. There are simply too many. An attempt has been made, however, to include as many possible in the text. Others, about whom there is insufficient information to include in a narrative, have been relegated to the appendix, where they are treated in the style of a biographical dictionary. The two most important and influential composers of the century, Gregorion Curto and Theodore von La Hache, are covered individually in chapters two and three, respectively. Their music represents all three of the important aspects of composition of the era: opera, salon, and sacred music. Louis Moreau Gottschalk, probably the most famous composer and performer of the period, has been omitted from this study (other than incidental references) because he has already received considerable attention from numerous other researchers. Likewise, another composer of note, Ernest Guiraud, has been omitted because, even though a native of New Orleans, he left America at an early age and never returned. He should more appropriately be considered in annals of French music. Research in this field, a vital part of the American musical heritage, is by no means complete. …

The purpose of this study was to analyze for reasons of interpretation the unaccompanied choral music of Felix Mendelssohn. What are the stylistic characteristics in each of the compositions selected for examination in this study? What comparisons and conclusions based on the analyses can be made concerning the character of compositional style in Felix Mendelssohn's unaccompanied choral music? What conclusions can be made concerning the interpretation of Felix Mendelssohn's unaccompanied choral music based on the compositional style of his music and an understanding of his musical attributes?

The chorale Wie schðn leuchtet der Morgenstern was popular from its very outset in 1589. That it has retained its popularity down to the present day is evident by its continually appearing in hymnbooks and being used as a cantus in organ compositions as well as forming the basis for other media of musical composition. The treatment of organ compositions based on this single chorale not only exemplifies the curiously novel attraction that this tune has held for composers, but also supplies a common denominator by which the history of the organ chorale can be generally stated.

For this study, the forms of the movements of forty-four symphonies of Mozart-those appearing in the Breitkopf and Hartel "complete" edition of his works- were analyzed. For convenience of reference, the symphonies are discussed in this thesis in their conventional numbering-that of the Breitkopf and Hartel edition- except for six symphonies that appeared in a supplementary volume and are inserted in this study into their approximately correct chronological positions.
