The trumpet is the oldest brass instrument that is commonly heard in classical music, but is also extremely popular in jazz ensembles and solo performances as well. Players buzz/vibrate their lips together while blowing into the mouthpiece to create a sound. Trumpet-like instruments were first used around 1500 BC as signaling devices, but the modern version of the trumpet with piston valves and brass tubing dates back to around 1820. There are many different variations of the trumpet but the most common one is the B-flat trumpet. Read more here: https://en.wikipedia.org/wiki/Trumpet
