1) Turn the music box upside down so that the bottom is facing up.
2) Locate the winding key hole on the bottom of the music box.
3) Insert the winding key into the hole and turn it counterclockwise until the music stops playing. Do not force it.
4) Remove the winding key and turn the music box upright again.
Note: If the music box is still playing after you've turned the key counterclockwise, you may need to gently pry the lid open and release the tension on the spring. Please handle the music box with care to avoid damage to its delicate mechanism.
