A rotation device is adapted to be installed between the bell of a musical wind instrument and the body of the musical instrument. One or more rotational devices may be controlled by the musician or someone else while the musician is performing and/or playing the instrument. The rotation device may control the speed of rotation, the direction of rotation, and the amount of travel of rotation. The amount of travel of rotation of the bell may be more than and/or equal to and/or less than a 360 degree rotation.
