This tremolo device includes a flat hand plate and a short mounting post welded perpendicularly to bottom of the hand plate. The hand plate is configured and bent to form a curved eminence and depression along one side, which provides additional structural integrity and rigidity to the tremolo device. The mounting post is adapted to rotatably connect to the bridge assembly of a stringed instrument. The mounting post elevates the hand plate over the bridge assembly and instrument strings. The musician can rest the palm of the picking hand on the top of the hand plate, which positions the fingers conveniently over the instrument's strings. The musician can push or pull on the hand plate to apply force to the bridge and change the tension of instrument's strings.
