The comparison of structural and formal traits in the concert grossi of Corelli's Opus VI and Vivaldi's Opus III will proceed in the following manner: first, the cycle as a whole will be taken up; next, the individual movements will be considered. Finally, in each instance of comparison, Corelli's music will be dealt with first.

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.

The selected works by the composers studied in this thesis might well stand as illustrative of the normal development of the use of the bass trombone near the close of the nineteenth century. Although notable progress was made by the cited composers in increasing the bass trombone's usefulness in the orchestra, each composer also continued to use the bass trombone as it had been used in previous years, such as in doubling bass parts, harmonic backgrounds, and for strong rhythmic punctuations.

In music, the term verismo usually refers to a realistic or naturalistic movement in Italian operas of the late nineteenth century. From the dawn of Italian opera four features have been manifested--umanita (humanism), sincerity (sincerity), passione (passion), effetto (not only theatrical effect but the supreme dramatic moment). The elements of verismo are among the characteristics present in the operas of Giuseppe Verdi where they reached a zenith of development. It is upon these veristic aspects, as identified in the second chapter, that the operas Cavalleria Rusticana and Pagliacci were based. Rigoletto, Il Trovatore, and La Traviata richly exhibit these elements of verismo which have been identified in the fourth chapter.

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?
