- Description: Numerous studies exist examining the link in solo singers between timbre and overtone spectra. The purpose of this study is to examine if similar results can be obtained by applying the same techniques to choral singing. The study is aimed at non-scientific readers and therefore introduces the subject with background to the relevant physics. In this study a number of recorded samples of choirs were taken from www.youtube.com and analyzed. The analysis included computation of long-term average spectra (LTAS) and singing power ratio‟s (SPR), which provided an indication of the relative energy in the higher overtone region of every choir. This was compared to a binary value judgment of the choirs. The results indicate that the SPR as applied to soloists cannot be directly applied to choirs. A link between SPR and a perceived “good” choral tone could exist but would have to be interpreted differently than in the case of soloists. It was also found that a possible link could exist between frequency peaks in LTAS and a choir‟s intonation.

- Description: This study proposes a view of theatre voice as central to performance. It proposes a shift in paradigm through the foregrounding of the function of theatre voice as one of the creative strands of the theatre matrix. The function of theatre voice becomes a theatrical function. Theatre is created in the voice and, therefore, any act of theatre should include conscious questions about the meanings that are, or can be evoked through the voice in theatre. A second thrust to this study is that theatre voice practice should be included in, and theatre voice practitioners should actively engage in, broader debates about theatre. Introduction: The idea that the voice in performance is the enactment of conscious theatrical choices is set up through the notion of the theatrical use of the voice. The introduction outlines the kinds of performance contexts in which a theatrical use of the voice takes shape. This includes an assessment of the degree to which the specific South African context of the writer is useful to questions about a theatrical use of the voice. The concepts which are central to such a view of theatre voice are expanded. These are: the theatrical agency of the actor, theatre voice, the theatrical use of the voice and praxis. Selected examples from local and other productions are offered to illustrate a range of interpretive possibilities open to the voice when considered, in the first instance, as performance. Chapter one: The actor’s relationship with voice is explored through the notion of actor agency. Historically, actors were theatrically empowered by a closer involvement with playwriting, staging, apprenticeship forms of actor training and theatre management. It is argued that the emergence of the director as a new theatrical agent has diminished this actor agency. On the other hand, the introduction of a realist acting methodology has given the actor autonomy of craft, empowering the actor in unprecedented ways. The theatrical agency of actors, directors and theatre voice practitioners is explored as influencing the status and the perception of theatre voice within theatre. The proposal of the centrality of voice to performance is dependent on the agency of actors, directors and theatre voice practitioners. Chapter two: It is argued that an Aristotelian Poetics of Voice has, under the influence of realism, developed into a “Poetics of the Self”. The paradigmatic shift proposed through a view of the voice as central to theatre, is explored through a post realist, intertextuality of voice. This includes a re-consideration of the contemporary theatre voice notion of the “natural” voice. Chapter three: Cicely Berry’s work, with particular reference to The Actor and his Text (1987), is analysed in terms of realism and the theatrical use of the voice. A second focus in the analysis of Berry’s work supports the argument that voice practitioners theorise positions for theatre voice even though their texts are practical and technically orientated. Berry’s work is singled out here because the contemporary practice of the Central School tradition is the generic tradition of South African English theatre voice practice. Chapter four: Strategies and constructs are proposed in support of the centrality of voice to the theatre. Ways of realising a theatrical use of the voice are also suggested. This is based on a shift in the way in which practitioners think about theatre voice. In the first instance, it is suggested that practitioners move beyond positions of polarity and actively embrace that which is contradictory in theatre and theatre voice practice. Secondly, a traditional hermeneutic understanding of the interpretation of voice is challenged. Thirdly, the use of metaphor which is pertinent to actors, directors and voice practitioners is explored as a means to vocal action. Concrete examples of the creative use of the voice, are provided through the sonic texts of Performance Writing. By way of conclusion, some ideas are offered about the issue of empowering the actor in a theatrical use of the voice. This study is intended to contribute to a theoretical and practical debate which will promote the argument for the centrality of voice to performance.

- Description: Voice training has been influenced by separatist attitudes which have allowed for classes which train the body to be separate from those which train the voice. This study acknowledges that to train an actor in separate compartments and then expect the completeness of human expression in performance, is to train under false pretences. There is a need to address the imbalance of separatism and this is examined within the context of voice training. An holistic approach to voice training forms the basis of the argument, which focuses on the need to re-educate the notion of physicality in voice training. Chapter one proposes an understanding of the notion of physicality by drawing on the attitudes of selected theatre practitioners towards the physical nature of the theatre encounter. The expressive energies of the actor's body are responsible for the physicalisation of a play; for this reason the movement of voice and speech is not only examined as source movement, but also as the movement of an actor's response and communication. Chapter two examines some practices which led to attitudes of separatism in voice training, and introduces prevalent practices which are attempting to involve the energy of the physical experience. Chapter three proposes that the Alexander technique be used as the foundation for an awareness of individual physicality. Where chapter one examines the theory of this notion, chapter three proposes an experiential understanding of the same. The Alexander technique is a training in effective body use and it's principles are fundamental to an awareness of body use and functioning. It is argued that these principles should underlie a re-education of physicality. The final chapter of the thesis argues for physicality in South African voice training programmes which would complement the physicality of contemporary theatre forms. It is hoped that this study will provide further incentive for the continued review and adjustment of drama training in South Africa.
