Fragment (2020) for Prepared piano

It's a long piece of music for the title "Fragment," but musical time is proceeding only slowly by persistently repeating some of its fragment. For example, smashing a bottle is an instantaneous event for us, but when we film it and play it back, we can advance the playback time little by little by repeatedly rewinding the moment when it's smashed. The musical time of this piece is almost like a video that has undergone such an editing process.
