“Sistema di prossimità”

Sistema di prossimità has been written within the project “Composing with piezo”. Piezoelectric microphones transduce sound energy directly transmitted by the vibrating surface of the instrument where they are placed, changing considerably its original sound quality. In Sistema di prossimità they are used not only to amplify the instruments, but also to play different idiomatic gestures — such as glissando, tapping, scraping —  introducing a new palette of sounds. The instrumental sound matter becomes less predictable, bringing new questions within the compositional process.
