I am interested in the psychological notion of flow and what this can mean in relation to performance (performing and reception):
‘[...] flow, or optimal experience, [is] related to many similar experiences that share the same structural attributes - deep concentration, a sense of control and freedom made possible by a balancing of challenges and skills, and a continuous development of meaningful complexity - experiences that follow immersion in religious rituals, in athletic competition, or in the performance of music or playing chess, in fact, any of a great number of structured interactions with the environment that result in deep enjoyment.’
