How do artistic and scholarly approaches and experiments affect how we experience time? How is our conception of time shaped by representations? The talk explores how time is frozen or accelerated in experiments, fixed in musical notation, or can be made perceptible in free improvisation, while scholarly, musical and artistic approaches will be brought into dialogue. Strictly composed experiments in the realm of quantum physics and music will be experienced as “comprovised” experiments between a preconceived concept and spontaneous improvisation.
