How does technology inform, shape, mediate and constrain our conceptions and practices of performance? This issue begins with an expanded understanding of ‘technology’. Not only specific technologies (notation, the oboe, recording, the internet, VR), but also wider technological discourses of practical, environment, and conceptual thought-space (heliocentrism, the steam engine, computation and our common extended reality).
The tesseract is a gravitational wormhole that represents the physical compression of space that circumvents time in order to move from one location in spacetime to another. The index, as part of the body, but also the mechanism for applying a collapsed signification, requires both utterance (mediation) and event (temporal-frame) in order to create cognitive meaning.
