Neodymium magnets are attached to the rotating fan inside of an A/C to make A/C Harp. It produces sound from a guitar amplifier when a player catches the changes of electromagnetic fields caused by the rotation of the fan as electric signals with coils attached to fingers. Musical scales can be played by changing the number of magnets and distance between magnets . Rotation speeds also change the pitch.
A/C s are reincarnated to electromagnetic harps and spin music from season to season.
