ABSTRACT:
A drum or other percussion instrument is held suspended in air by magnetic force fields which allows sound vibrations to radiate from the instrument uninhibited by direct contact of the instrument with a support structure. Magnetic force is provided by permanent magnets or electromagnets. A first set of magnets is connected to a percussion instrument and a second set of magnets is connected to the framework of a support structure. Poles of the first set of magnets face like poles of the second set of magnets. Magnetic repulsion suspends the instrument on a cushion of magnetic force and contains the instrument from moving off the cushion of magnetic force.
