The chromatic trumpet of Western tradition is a fairly recent invention, but primitive trumpets of one form or another have been in existence for millennia; some of the predecessors of the modern instrument are now known to date back to the Neolithic era. The earliest of these primordial trumpets were adapted from animal horns and sea shells, and were common throughout Europe, Africa, India and, to a lesser extent, the Middle East. Primitive trumpets eventually found their way to most parts of the globe, though even today indigenous varieties are quite rare in the Americas, the Far East and South-East Asia. Some species of primitive trumpets can still be found in remote places, where they have remained largely untouched by the passage of time.
