Nut for musical instrument

A nut for a musical instrument, comprising:

• a clamp jaw having an opening through which a stand is passable, the clamp jaw being configured to, in a state of the stand being disposed in the opening, change a size of the opening by changing a position of the clamp jaw between an open position and a closed position;
• an elastic member configured to, in a state of the clamp jaw being in the closed position, clamp the clamp jaw to the stand by exerting a force directly on the clamp jaw;
• an operating element having a pressing portion and a front end portion;
• and
• a housing accommodating the clamp jaw, the elastic member, and the operating element,
• wherein in the state of the clamp jaw being in the closed position, the front end portion of the operating element hinders the clamp jaw from moving to the open position by contacting the clamp jaw and the housing, and
• wherein in a state of the clamp jaw being in the open position, the front end portion of the operating element presses the elastic member such that the elastic member does not exert the force directly on the clamp jaw and the pressing portion of the operating element presses and spreads the clamp jaw open.
