Abstract: Instrument chin support, and method providing a means for adjusting placement along any and all 3-dimensional axes (x, y, z). An assembled chin support can include a chin-plate shaped to provide the player with comfort; a ball joint and clamp that allow the adjustment of any or all angles in the x, y and z axes (i.e. rotation, yaw, pitch, tilt, and roll); an eccentric post that mates with a base-clamp so as to provide the player with a means to customize the height and lateral position (i.e. y and z axes) of the chin-plate; and a bracket commonly known in the art to affix the chin support to the instrument. Advantages include providing players with a chin support that players can customize to their individual body. By doing so this chin support can help alleviate most of the adverse health concerns many players struggle with while playing their instrument.
