This thesis investigates cross-modal interactions in auditory and visual perception, focusing on the perception of expressive musical performances. A primary aim of the work is to advance knowledge pertaining to how and when musicians' body movements influence an observer's overall experience. Three studies, comprising two multi-factor experimental investigations and one theoretical contribution, explore the multi-modal experience of musical performance. The two empirical chapters investigate, respectively, (1) the real-time experience of musical structure and musical emotion, comparing unimodal and multimodal conditions, and (2) the multidimensional structure of affective responses to musical performance, as a function of sensory modalities and performance intentions. The theoretical chapter develops a class of quantitative models for studying real-time phenomena in music (in particular) and time-series data (in general). An original contribution of this thesis is to quantify the ways in which the auditory and visual components of musical performance contribute singly and in interaction with one another to overall experience. The studies show that seeing a musician performing can augment, complement and interact with the auditory component to significantly influence music perception. These results are relevant to, and inform theories on, multi-sensory integration, emotion, and music cognition, as well as performance practice and audio-video media.

This qualitative mini-treatise explores Musical expressivity in choral singing with reference to three High School choirs in the Port Elizabeth area. Singing with emotions is not only a facial expression of some sort. There are so many more aspects which could be applied in order for the choral performance to be of an outstanding nature and not merely a performance. The researcher questioned the possibility of introducing expressiveness into rehearsals and performance through the application of more expressive conducting techniques, more detailed musical aspects and a general sense of unity within the group. The choral conductor plays a primary role and should therefore be considered as the most important link between choir and excellence. Focus is put on specific warm up exercises and suggestions are put forward regarding the development of your own, personalized exercises which suits your own unique setup. Data was collected through open-ended interviewees of the three school choir conductors as well as data from current and past studies on various topics. The perceptions of these conductors were noted and the manner in which they apply Musical knowledge during their rehearsals. Research findings indicate that not enough emphasis is put on expressive singing during rehearsals. More research done by the conductors and attending workshops are recommended for personal growth and development.

"The purpose of this study is (1) to obtain definite information in regard to the theory that musical capacity is inherited; (2) to determine whether or not a favorable environment is necessary in the early musical training of an accomplished musician; (3) to indicate the effect of early musical training on a successful career in music"--Introduction. / "August, 1953." / Typescript. / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Music Education." / Advisor: Robert L.

The purpose of this study was to determine differences between the same subjects' music preferences at the elementary and high school levels, and the relationship between these findings and the following variables: peer preferences, musical training, excerpt familiarity, grade, gender, and race.

The purpose of this study was to investigate changes in selected children's Graphing Response Patterns to elemental changes in compositions in theme and variation form. The research problems were (1) to determine points and degrees of elemental change in the compositional structure of the musical examples; (2) to determine number, degree, and nature of changes in subjects' graphing response pattern to aurally presented musical examples; (3) to determine percentages of agreement between changes in graphing response patterns and points of elemental change within the compositional structures; (4) to determine the relationship of changes in subjects' graphing response pattern to the quality and magnitude of elemental change within the compositional structure. Twenty second- and fourth-grade children were individually videotaped as they listened to and graphed a series of aurally-presented musical examples. Each musical example was analysed according to such parameters as timbre, range/interval size, texture, tempo/meter, attack/rhythmic density, key/mode, dynamic level, and melodic presentation. Change in each parameter was scored using an interval scale reflecting change/no change and degree of change. Changes in graphing response pattern were determined by an interval scale which reflected the presence of change/no change and amount of change, using as analytical units speed, size, shape, type, and pause. The following conclusions were made: findings showed an observable, quantifiable relationship between changes in children's graphing response patterns and elemental changes in music parameters. This relationship encompassed not only change/no change judgements but also magnitude of response. Overall, frequency and magnitude/degree of student response was proportionate to the frequency and magnitude of change in the music parameter/s. Results indicated the existence of high-ranking correlations between student response and certain parameters regardless of the degree-of-change/points-of-change ratio. Findings showed that one degree of change in a single music parameter was not sufficient to cause an observable change in the attention of the young listener.

A dissertation submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for a Masters degree with the Faculty of Humanities (Health Communication and Music). Johannesburg, May 2017 / This dissertation synthesises the fields of narrative medicine and music composition to address the experience of delirium, and to learn whether music has a role to play in understanding and communicating its nature. My submission takes the form of a written dissertation accompanied by a new musical composition, Delirium Part II. Both written and composed texts are based on interviews and small discussion groups with people who have experienced delirium, their families, and healthcare professionals who are familiar with delirium in people under their care – as well as observation and recording from a hospital intensive care unit (ICU). The composition incorporates both interviews and ambient hospital sounds as audio components, and was performed first on 2 March 2017 at the Music Room, University Corner, University of the Witwatersrand. The study addresses significant gaps in our understanding of delirium, from its definition to the qualities of the experience for all those affected by it. Violence is shown to be inherent to the experience, driven by a cycle that imposes it by turns on HCPs and patients. Delirium is, moreover, characterised by losses of numerous kinds: orientation, dignity, control, and ultimately personhood. This study suggests, however, that it is within our grasp to limit significantly the impacts of these losses through re-evaluating our interactions with patients and families and challenging the dehumanising aspects of care. The music of Delirium Part II, moreover, is shown to have the capacity to contribute to this re-evaluation. There are clear indications here of the potential for music and the arts more broadly to convey complex health experiences, and to be of use in training and education. Music contributes centrally to the development of this research, as a tool both for data analysis and for provoking discussion of a complex, emotive topic. The possibilities for creative practice in narrative medicine are illuminated by this cross-disciplinary study, which demonstrates both that narrative-based musical composition can teach us much about delirium; and that delirium can teach us much about care. / MT2018
