The violin shoulder rest, also known as a shoulder pad, is an accessory used for playing the violin. It is installed at the lower end of the back panel of the violin case, fixed on both sides of the violin, and cannot come into contact with the back panel. It plays a role in separating the back panel from the human body and not suppressing vibration. It can also elevate the violin case, making it more convenient for performers with long necks to use. Playing can make the piano case smooth and comfortable.

There are several types of shoulder rests made of wood, metal, and plastic, and the ones with better wood quality are all made of maple wood. No matter what kind of shoulder support, it cannot come into contact with the backboard. Its support points are concentrated on the edges and side panels of the piano board.
