The research focused on the identification and ranking of critical success factors that contribute most significantly towards the training of a cello student. The empirical study was based on a sample of cello teachers in four countries selected for the study, namely Germany, Russia, the United Kingdom and the United States of America. A literature study, identifying a broad category of factors that could contribute towards successful cello training, formed the basis of the questionnaire. These critical success factors included the quality of the teacher, acquired skills, the talent and giftedness of the student, support rendered to the student, and the curriculum. Each of these factors comprised five sub factors. The respondents were required to rank these factors in order of importance. In the final analysis, they were requested to rank the five main factors. A statistical process of ranking (forced ranking) and Kruskal-Wallis was applied to rank and analyse the responses of the cello teachers in the survey. The critical success factors that contribute the most significantly towards successful cello training were identified and compared.

This thesis explores a performance practice within free improvisation. This is not a theory based improvisation – performances do not require specific preparation and the music refrains from repetition of musical structures. It engages in investigative and experimental approaches emerging from holistic considerations of acoustics, interaction and instrument, and also philosophy, psychology, sociopolitics and technology. The performance practice explores modes and approaches to working with the given potentiality of an electronically augmented acoustic instrument and involves the development of a suitably flexible computerised performance system, the piano+, combining extended techniques and real-time electroacoustic processes, which has the acoustic piano at its core. Contingencies of acoustic events and performance gestures – captured by audio analysis and sensors and combined to control the parameter space of computer processes – manipulate the fundamental properties of sound, timbre and time. Spherical abstractions, developed under consideration of Agamben’s potentiality and Sloterdijk’s philosophical theory of spheres, allow a shared metaphor for technical, instrumental, personal, and interpersonal concerns. This facilitates a theoretical approach for heuristic and investigative improvisation where performance is considered ‘Ereignis’ (an event) for sociopolitically aware activities that draw on the situational potentiality and present themselves in fragile and context dependent forms. Ever new relationships can be found and developed, but can equally be lost. Sloterdijk supplied the concept of knowledge resulting from equipping our ‘inner space’, an image suiting non-linearity of thought that transpires from Kuhl’s psychological PSI-theory to explain human motivation and behaviour. The role of technology – diversion and subversion of sound and activity – creates a space between performer and instrument that retains a fundamental pianism but defies expectation and anticipation. Responsibility for one’s actions is required to deal with the unexpected without resorting to preliminary strategies restricting potential discourses, particularly within ensemble situations. This type of performance embraces the ‘Ereignis’.

This thesis presents a performer’s view of Galina Ustvolskaya and her music with the aim of demystifying her artistic persona. The author examines the creation of ‘Ustvolskaya Myth’ by critically analysing Soviet, Russian and Western literature sources, oral history on the subject and the composer’s personal recollections, and reveals paradoxes and parochial misunderstandings of Ustvolskaya’s personality and the origins of her music. Having examined all the available sources, the author argues that the ‘Ustvolskaya Myth’ was a self-made phenomenon that persisted due to insufficient knowledge on the subject. In support of the argument, the thesis offers a performer’s interpretation of Ustvolskaya as she is revealed in her music. The author examines Ustvolskaya’s music from two viewpoints, a scholar and a performer, and draws upon inter-textual connections between Ustvolskaya’s music and Russian literature (Gogol, Dostoevsky, oberiuty) and aesthetics; analyses the influences of Russian musical traditions (Russian folklore, znamenny raspev) and some artistic individuals (Mussorgsky, Shostakovich, and Stravinsky), and examines the nature of Ustvolskaya’s spirituality and religiosity. The performance aspects of Ustvolskaya’s music are discussed as well as the specific nature of her writing for instruments, particularly the piano, and the interpretation and perception of her music by both the performers and the audience. The thesis examines the performance history of Ustvolskaya’s works, and draws on interview materials with musicians who knew the composer and performed her music. The author’s own performance experience and that derived from the ‘Ustvolskaya at Chetham’s’ project which involved young musicians in studying and performing Ustvolskaya’s compositions, underlined the practical value of the research. While supporting the view of Ustvolskaya as a singular composer, the thesis stands to demystify and reevaluate her artistic image.

My argument is that gender visibility in live and mediated performance can be enhanced by the use of the dramaturgical toolkit. The thesis as a whole offers a body of work and a method for recontextualising that work, and for reframing it in multimedia format. The visual and written texts on the DVD-Rom give equal weight to the performance and written research comprising this submission. Building upon that set of materials and meanings, but leaving deliberate gaps and spaces for debate and interpretation between them as well, I have attempted to offer a useful but also a flexible toolkit for use by future practitioners and scholars. Method: Taking as my case study Di's Midsummer Night Party, a site-based devised performance (this collaboration in 2000 was created with a scenographer, five professional actors and 20 extras, performed over five nights in an 18th-century house), I design and theorise a dramaturgical toolkit. The theoretical base is developed from established theoretical concerns, feminist performance theory and social semiotics to analyse an original contemporary performance work. Original contribution: The dramaturgical toolkit is designed to be used by artists, students and academics. My analytical tool is being used in teaching and is valuable to others who want to teach/research gender representation in live and mediated performance. Tests during development and subsequently have taken place with performance design and fashion students at Central Saint Martins College of Art and Design, where the kit encouraged the articulation and analysis of student work. The dramaturgical toolkit helps the facilitator to push students towards articulation and analysis of "bite-sized" bits that are distilled enough to be clear, and therefore useful for making and analysing performance. This process of distillation helps artists and students to focus down and to reach new levels of understanding.

This thesis identifies and analyses the key creative protocols in translocal performance practice, and ends with suggestions for new forms of transversal live and mediated performance practice, informed by theory. It argues that ontologies of emergence in dynamic systems nourish contemporary practice in the digital arts. Feedback in self-organised, recursive systems and organisms elicit change, and change transforms. The arguments trace concepts from chaos and complexity theory to virtual multiplicity, relationality, intuition and individuation (in the work of Bergson, Deleuze, Guattari, Simondon, Massumi, and other process theorists). It then examines the intersection of methodologies in philosophy, science and art and the radical contingencies implicit in the technicity of real-time, collaborative composition. Simultaneous forces or tendencies such as perception/memory, content/ expression and instinct/intellect produce composites (experience, meaning, and intuition- respectively) that affect the sensation of interplay. The translocal event is itself a diagram - an interstice between the forces of the local and the global, between the tendencies of the individual and the collective. The translocal is a point of reference for exploring the distribution of affect, parameters of control and emergent aesthetics. Translocal interplay, enabled by digital technologies and network protocols, is ontogenetic and autopoietic; diagrammatic and synaesthetic; intuitive and transductive. KeyWorx is a software application developed for realtime, distributed, multimodal media processing. As a technological tool created by artists, KeyWorx supports this intuitive type of creative experience: a real-time, translocal “jamming” that transduces the lived experience of a “biogram,” a synaesthetic hinge-dimension. The emerging aesthetics are processual – intuitive, diagrammatic and transversal.
