This study investigates the effects of frequency variance on duration perception, using musically trained subjects. In the experiment three silent duration intervals were examined (4.75, 5.00, and 5.25 seconds); each interval was preceded and followed by tone markers. The onset marker was preceded by seven discrete tones one second apart, on the frequency 174.968 Hertz. This established a pulse or an external standard time measure. The subjects made judgments as to whether the offset marker fell "before," "on," or "after," the pulse. The offset marker had a variable frequency. In the study, the direction of the frequency change, the distance of frequency change, and the mathematical intervallic relationships of the two frequencies show possible influence on duration perception.

The problem with which this investigation is concerned is the determination of compositional styles in terms of manners of employing monadic and dyadic intervals in the music of the common practice period. An aspect for determining style is proposed by way of comparing the frequency of occurrence of dyads and monads in selected musical examples from the baroque, classical, and romantic periods. Chapter I is a discussion of the problem and methodology of the study. Chapters II, III, and IV present analytic comparison of examples in the baroque, classical, and romantic periods respectively. Chapter V presents a summary of the findings with references to the pedagogical applications of the two-part framework principle.

The purpose of this study is to examine the pitch content and compositional techniques of Takemitsu's recent solo piano works, which have not been analyzed by Koozin, and to trace the evolution of his techniques in his solo piano works during his career. It also discusses how Takemitsu projects his philosophy and aesthetics of musical composition through Western musical idioms.

For the purposes of expressive intent, Carter developed compositional strategies that possess qualities congruent with the musical language in his Second Quartet (1959). He employed strategies including tempo modulation, triple groupings, and large-scale ratios to assemble the musical discourse and to guide the listener's perception of large-scale continuity. I label these devices collectively as "preferential strategies" because it is Carter who selects certain pre-compositional ideas that organize musical material and demarcate structural locations. Tempo modulations that organize dual meters and triple groupings that interact in transitional and transformational ways demonstrate his concern with controlling the overall time continuity through local level organization. Large-scale ratio relations between nine interlocking sections of this four movement work illustrate how Carter employs a local strategy that projects a large-scale structure. Recognizing that Carter's ultimate compositional goal prioritizes temporal processes, these proposed preferred strategies articulate a convergence of musical elements.

Heroes Are Born Then Made is a theatre piece involving live actors on stage, and live music originating from an orchestra pit. The script and music is original. The music is meant to literally depict actions and emotions on stage whether the actors are present or not. The duration of the entire production is about two and one-half hours long. Six main actors are used with additional walk-ons. Sixteen musicians are required to make up the orchestra which is organized into a woodwind quartet, a brass trio, a string quartet, a piano, and a percussion quartet. The play is based on the author's conception of how people tend to treat each other when someone is caught at a disadvantage. Specifically it is a depiction of the conflict involved when the minor characters discover that the main character is trying to do something quite different from their definition of "normal."

This study seeks to discover the extent and manner of Debussy's use of the motive in thematic material. A total of 40 melodic examples were analyzed in order to show their relationship to a single motive, a three-note figure having a step-leap relationship. Using eighty-four series of examples, the study shows the melodies analyzed to be 85% motive-derived. The study concludes, therefore, that Images I is a remarkably economical work, using a single three-note motive as a unifying and developmental basis.

Mahler's Ninth Symphony, since its premier in 1912, has sparked much debate about its programmatic meaning. This thesis provides an in-depth analysis of the Adagio and an examination of the controversy of the farewell story. In the process of the analysis I have compared my findings to some of the important authors in Mahler's field such as Vera Micznik, Henry-Louis de La Grange, and Christopher Orlo Lewis. Some of the conclusions are that a closer investigation of the music is necessary and that the programmatic reading of the farewell story can be appropriate.

The problem is to relate four parameters, thematic development, chord tension, tonality, and rhythm to musical Growth in Karel Husa's Music for Prague 1968. The analytical technique consists of determining a typology and relating that to Growth and is applied in small dimensions to the "Introduction" and in large dimensions to the whole composition. Movement in the composition is goal oriented, and each parameter contributes in different ways, one providing contrast, another continuity, and another variety. Shapes are delineated by cadences characterized by a decrease followed by an increase in Movement. Growth is characterized by Shapes in which Movement starts at a low level, moves to a climax three quarters through, and relaxes for the end of the Shape.
