Trumpet: Brief Description — Vienna Symphonic Library
“The trumpet in C consists of the trumpet tube and bell, the mouthpipe with detachable mouthpiece, three valves and the tuning slide, with which the overall tuning of the instrument can be altered. The tuning slide has a water key. In many cases, all three valves have valve slides which can be pulled out with a trigger to correct the intonation of individual notes.“
