Autonomous sound installation based on a feedback system for cymbal, electromagnets and microphone.The cymbal is subjected to impulses and set in vibration without ever being touched. It is excited by two different electromagnets, located at two opposite points of the cymbal and generating an electromagnetic field to which two small magnets applied on the cymbal react, causing it to vibrate. The resulting sound waves are captured by a microphone and digitally processed through an algorithm based on modulated delay lines and nonlinear syntheses. The processed signal is then reproduced again by the electromagnets, establishing a new state of vibration of the cymbal in a closed loop.
