I play trumpet
Very cool! A trumpet is a brass instrument used in jazz and classical ensembles, right?
Who invented the trumpet?
I'm not sure who, but trumpet-like instruments have been used on the battle field and as signaling devices since at least 1500 BC.
What are the trumpet like instruments you mentioned?
Any kind of instrument where you can blow air though with nearly closed lips to produce a buzzing sound.
Namely? Can you mention such?
I don't think they had names. I think they were just rudimentary trumpets made in the 14th and 15th century.
