Title: Percussion instrument head

Abstract: A percussion instrument head is composed of a synthetic resin film (e.g., a PET film) having a prescribed thickness, which is subjected to chemical etching using a prescribed solution (e.g., an alkali solution), thus processing at least one surface thereof to be rough. Irregularities are formed in substantially uniform sizes and dimensions on the rough surface of the film, wherein hydrolysis processing advances firstly on the surface of the film, which are gradually dissolved or decomposed. Thus, it is possible to simulate the exterior appearance and flexibility of the conventional natural-leather head, and it is possible to produce sharp and articulated sounds having balanced pitches (or intervals) when playing the percussion instrument head composed of the synthetic resin film, which can simulate the property of sound of the conventional natural-leather head. After completion of chemical etching, the film is coated with an epoxy resin, for example.
