This thesis uses two different musical analytical systems, one of Heinrich Schenker and one of Paul Hindemith, to analyze tonality within "Die Gurre Lieder" and "Fourth String Quartet" by Arnold Schoenberg.

The purpose of this thesis is to discuss and give a descriptive analysis of twelve of the twenty-four preludes written by Claude Debussy. This paper also includes a brief history of preludes as well as possible influences upon Debussy and his compositions.

The Sixth, Seventh, and E Piano Sonatas of Prokofiev illustrate the composer's more mature style. In these works there is a definite return to the classic forms and contrapuntal devices which have been called Neo-classicism. Prokofiev, himself, has said that form is one of the basic elements of his style. It is the purpose of this thesis to discover the' formal organization and make a comparison of these sonatas with the works of Beethoven and his contemporaries.

The purpose of writing the quintet for Woodwinds is to produce composition for woodwind ensemble containing elements of significant musical form. Much of the quintet music. by composers such as, Reicha and Taffanel is characterized by pure virtuosity of style and lack of significant musical form.

In the Third Movement (Playfully) the piccolo is to be used as an alternate instrument with the flute.

The application of information theory to music may provide both a means for measuring the information content of the messages .of the system and for studying the effects of such messages in the field of psychology of music (e.g., the group at Iowa University which is carrying on work commenced by Carl Seashore 3 ). Before the techniques of information theory may be applied to a study of music much statistical data about the music system must be compiled. Masking data must be compiled dealing with many simultaneous tones as are encountered in music; the effects of timbre in overcoming or adding to masking effects must be investigated; the effects of masking on and by the singing voice must be tabulated; and similar data must be compiled dealing with the effects of other types of tonal interactions. This data of the effects of tonal interactions may be used both to reduce the effects of such auditory phenomena and to determine which components of a message pass through the communication channel (i.e., the ear). The masking problem, as illustrated in Figures 19 and 20, may be so acute in some compositions that the part of the signal carrying the information content …

Benjamin Britten is one of the foremost contemporary English composers. He has successfully revived English opera, dead since Purcell, and this is one of his most significant contributions to the contemporary music world. Therefore, the purpose of this document is to give the reader some insight into Britten' s operatic style. The first chapter contains a sketch of Britten's life with particular reference to his operas, along with general characteristics of his writing. The following chapter has been devoted to a closer consideration of four of his2 operas: Peter Grimes, ;Theof. Lueretia, Albert Herring, and Gloriana. Since an analysis of entire operas would exceed the limitations of this paper, the soprano role has been selected as representative of Britten's operatic style. The vocal score of Turn of the Screw was not available for this study, and his other operas do not contain soprano roles. With each analysis a brief synopsis of the plot is included as a background for the musical analysis. Following the plot is a general treatment of the outstanding style features of the role. In order to present another facet of Britten's writing, the specific analysis of each soprano role is handled from a thematic standpoint. That …
