Zusammenfassung:	A piano key cover having a body of synthetic material pigmented to resemble natural ivory defines a top playing surface having a random orientation of peak-to-valley texture and a multiplicity of fine pores to replicate a surface of natural ivory. A multiplicity of the pores have diameters generally in the range of 0.0002 to 0.0012 inch (0.005 to 0.030 mm). The synthetic material is selected from the group consisting of acrylic polymer, polyurethane, epoxy and the like. A method for forming such a piano key cover and a piano having key covers of the invention are also described.
