Alessandro Perini – “Intorno alla traccia” (2020)
for clarinet with two MIDI-controlled side-keys and live electronics
Included in the CD “The Expanded Body”
I modified a Bb clarinet by 3D-printing a mount which holds two solenoids, pushing two of the side-keys. The piece features fingerings, speeds and polyrhythms which are impossible to a human performer. The motorized keys are programmed to interfere with the human action in this 10-minutes long pieces where circular breathing is prescribed throughout.
These motorized keys are controlled by a MIDI piano-roll via Max and Arduino. A scrolling video-score as well as automated live-electronics processes are also synced with the MIDI control.
Recorded by Natalie Eriksson in November 2020 at the Inter Arts Center.
Originally printed in PLA, I had to switch, for the 3d-printed mount, to nylon due to higher resistance to heat (the solenoids were reaching the melting temperature of the PLA).
