Abstract
A double deck rotational music box includes a base, a musical kit, a seal cap and a rotational upper cap. A spring knob is located above the base and engages the upper cap. Through turning a spindle and the spring knob, the upper cap and the ornament of the music box may rotate in opposite directions concurrently to produce novel visual and audio amusement effects. The spring knob may be turned easily and safely without turning over the base.
