A motion-based sound setting apparatus and method and motion-based sound generating apparatus and method. The motion-based sound setting apparatus includes a mode selection recognizing unit, a motion sensing unit, a motion pattern recognizing unit, and a sound signal setting controlling unit. The mode selection recognizing unit recognizes a user's action with respect to a sound setting mode or a sound generating mode. The motion sensing unit senses a motion of a predetermined device and outputting a result of the sensing as a sensing signal. The motion pattern recognizing unit recognizes a motion pattern of the predetermined device, which corresponds to the sensing signal, in response to a result of the recognition made by the mode selection recognizing unit. The sound signal setting controlling unit sets a sound signal corresponding to the motion pattern recognized by the motion pattern recognizing unit.
