A process for forming a Caribbean steel pan consisting essentially of:
- (a) determining the shape and dimensions of a selected Caribbean steel pan or determining an average shape and dimensions of more than one selected Caribbean steel pan;
- (b) creating a compilation of topographic data of the shape and dimensions of the pan or pans;
- (c) using the resulting compilation to form a mold to substantially replicate the shape and dimensions of a single pan or the average shape and dimensions of more than one selected Caribbean steel pan;
- (d) incorporating the mold into a hydroforming press;
- (e) pressing a sheet metal disk having a desired diameter and a substantially uniform thickness in the hydroforming press to form a steel pan head having a plurality of individual raised convex note producing shapes formed therein, which produce a resonant sound when struck by a mallet;
