The problem is a study of the relationship of selected musical and extra-musical variables to sight-singing ability.

The purposes of this study were (1) to categorize examples of vowel sounds by means of subjective evaluation, (2) to ascertain by spectrographic analysis the distinguishing characteristics of the acoustical properties of the examples in the categories, (3) to determine the similarities and dissimilarities which exist within and between the categories, and (4) to analyze the implications of the findings for the teaching of choral singing.

The purpose of this study is to describe contemporary plans for training the boy's changing voice and to prescribe ensemble material for these voices. Specific Problems: Analysis of the general problem leads to subordinate questions, or sub-problems, which may be stated as follows: 1. What are the contemporary plans of training the boy's changing voice? 2. What are the most usable musical materials available for use by ensembles which include boys with changing voices?

Both science and empirical knowledge seem to indicate that anatomical considerations relating to potential muscular interference be established at the incipiency of the serious study of voice. Experience shows that if this aspect of vocal development is not pursued with utmost diligence, an early deterioration of the vocal instrument is possible many years before a normal expectancy. It has been discovered, also, that the study of articulation, pronunciation, modulation, emphasis, gestures and interpretation seem to avoid, primarily, the necessity of muscular training, per. This thesis will not include, in detail, the aspects of the use of the breath, except in a perfunctory manner. The same can be said of resonance and diction. It will endeavor, however, to indicate the muscular differences of the singing and swallowing actions. Furthermore, it will advance some suggestions for the avoidance of constrictive muscular influences which might impede the singing musculature. Finally, a phonatory process will be presented for consideration as a muscular mechanism to be made operative in connection with a direct control procedure.

M.Mus. Faculty of Humanities, University of the Witwatersrand, 2008 / This report forms part of the output of a research team investigating the phenomenon of overtone singing as practiced by the women of the Ngqoko Women’s Ensemble in the village of Ngqoko outside the town of Lady Frere in the Eastern Cape, South Africa. This essay examines various systems of musical notation in terms of their possible application in the transcription process of overtone singing as found amongst these women. A selection of their music is transcribed using the formulated notational systems and the effectiveness of these systems is compared. A recommendation as to which system of notation is most effective for documenting this type of music is made. Utilising the soundworld of the Ngqoko recordings, an original piece of music is composed as part of this submission.

The integrated method proposed and worked out consisted of integration of vocal and voice-speech teaching techniques as well as integration of the empirical and mechanical methods of teaching. Balance and co-ordination between external and intra-pharyngeal articulation were considered as a framework for integration of various methods of teaching. Magnetic resonance imaging (MRI), along with spectral analysis, was used to demonstrate the work of intrapharyngeal muscles while singing and to assess the quality of vocalization. 54 MRI expositions were generated for the set of vowels, pitches and modes, of which over 400 MRI images were synthesized and measured. When switching from amateur to professional way of singing, radical transformations of size, shape and to some extent, changes in the surface properties (density, porosity) of muscular tissue of intra-pharyngeal cavities were observed. New acquired MR images clearly showed that the axial section of the back cavity appears indeed much larger in the professional mode than in the amateur mode. Statistical analysis showed that this difference is statistically significant. It is shown that the work on muscles development and use of mental images/imagination must progress in close collaboration. The strategy for the gradual mastering technique of the opening of the vocal tract was suggested, and developed. A new approach was developed to be applied for students to get stable repeatability when they work with mental images. Obtained MR images were used as a part of visualization method during experimental work with students. MR images helped students to create proper mental images. The theory of tangible images was suggested and then successfully applied in the form of experimental work with students. Experimental work with students of the ethnic group Maori was conducted. This experimental work with Maori students demonstrated that the integrated method of teaching helped to overcome some physiological and psychological specific problems which require special techniques of training. Case studies were carried out to assess individual and students' group perceptions, along with interview techniques and a survey questionnaire. The results of the survey are presented graphically, and statistical processing of the data was performed. The results of the survey are interpreted and discussed.
