Trumpets have been around for a long time, dating all the way back to 1500 BC and even earlier in some cases. The first trumpets, made of silver and bronze, were discovered in an Egyptian tomb belonging to Tutankhamen. Scientists have also dated metal trumpets back to China around the same time period as well as bronze lurs from the Scandinavian area.
As time progressed, there were more features added to the trumpet, such as decorations located in the middle area of the instrument. In 300 AD, art from Peru showcased trumpets. In general, however, trumpets were mostly used for military, religious and signaling purposes in ancient times and they didn't become a playing craft until medieval times.
Although trumpets have come a long way with regards to valves, composition and the way they are made, the primitive and ancient trumpets were a glorious foundation upon which to build.
