This project was an exploration into the improvisational practice of scat singing. It looked at the fundamentals of inter-practice discourse between vocalising and tap dancing and offered a personal examination of Cesca's own practice and potential for further development. The work looked at developing coherent improvised conversation between herself and a tap dancer, and the methods which could be used to enhance this connection. It not only looked to demonstrate that they were able to communicate, but more specifically, to understand how they did so, offering an in-depth analysis of improvisational practice and potential. The research utilised a practice as research model which employed literature and practice reviews, interviews, workshops, and live performance. The work also aimed to inspire new potential avenues of research regarding jazz vocalising and improvisation.
