Abstract: A universal body pad for string musical instruments such as violins or violas. The pad is made of a unitary body having a cushion portion and an arm portion that conform to a player's body. Both upper and lower surfaces of the cushion and arm portions of the pad frictionally engage with the player's apparel and shoulder, respectively. The upper and lower surfaces can be either smooth or uneven. The cushion portion is curved at its upper surface and recessed at its lower surface to support the instrument and allow non-slip contacts with the player's body or undergarment and the player's apparel or outer garment. The arm portion is extended from the cushion portion to allow additional non-slip contacts with the player's body undergarment and the player's apparel or outer garment. An additional layer, which is made of same or different material and configured with same or different surface pattern variations, may be added to the pad at its lower and upper surfaces for extra comfort and/or friction.
