Abstract: A modulated electromagnetic musical instrument and sound reproduction system includes an acoustic carrier signal source, a modulation signal source, a linkage element, and an acoustic output. The acoustic carrier signal source is produced electromagnetically or mechanically via human instrument playing. An electromagnetic modulation source mixes with the acoustic carrier signal within a linkage element to produce a nonlinear behavior. This nonlinear behavior's coupled interaction with a physical medium or acoustic body produces sideband frequency components to form unique musical sound outputs and audio effects.
