Abstract
A musical performance riser having an interior area and a rigid block made from multiple layers of foam material of varying densities incorporated within that area. The block further includes a number of holes or chambers to trap sound. When the riser is used in performances, sound waves created by the object placed on the riser are reduced or dissipated as they travel down the block through the foam layers and chambers with the result being reduced acoustic interference and a better listening experience for the audience. The riser also includes specialized removable casters supported against rubber isolation feet that further serve to reduce the unwanted interference.
