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.
A number of models can be retuned from C to Bb by means of an extended tuning slide or an additional piece of tubing.
The above shown C trumpet is a German model, i.e. it has rotary valves and was made in the Viennese style:
- the tube walls are slightly thinner
- one extensible valve slide for tuning adjustment (for C#4 and D4)
- two additional keys which facilitate the playing of the notes A5 and C6.
The German concert trumpet is used mainly in German, Austrian and eastern European orchestras. In the rest of the world the French model with the Périnet system of piston valves and a narrower bore is far more common; indeed, in France and America it is practically the only model used. The French model has also been widely accepted in jazz.
