The present invention provide for a drumhead, or the head of any percussion or related instrument, such as a tambourine, which includes a layer in which a hologram image is formed which incorporates a thin metal coating conforming substantially to the contours of the hologram, and a dark colored synthetic substrate, to which the bottom surface of the layer of film incorporating the hologram is laminated. The thin metal coating, often aluminum as the metal alloy of choice, is applied utilizing a process commonly known in the art as "metalizing", wherein the molecules of the metal are dispersed relatively evenly over a given surface by the decomposition of the metal in its gaseous form. The coating is deposited to a thickness that allows approximately 65% light transmission through the hologram forming film layer and enables the dark colored substrate beneath to enhance the dramatic and colorful light effects ultimately achieved by the invention.
