A device and method is disclosed for creating a customized chinrest for a violin or a viola, molded to conform to the precise idiosyncrasies of a player's chin and jaw, rendering greater comfort, support, range of motion, and control to the player. The chinrest of this invention is comprised of a rigid, flat, edgeless base upon which a removable, firm, but flexible silicone, custom molded top is adhered. The method of impression taking records complex contours, angles, and a range of motion created by head pivot of the player's chin and jaw while in the act of playing.
