A pocket trumpet corresponds to the tube length (with mouthpiece 140 cm) - including pitch - of a normal trumpet , but is more compact (more frequent tube windings) and therefore not to be confused with the similarly small piccolo trumpet: While the overall length of a normal trumpet is approx. 49 cm (55 cm with mouthpiece), a pocket trumpet only reaches approx. 22 cm (25 cm with mouthpiece). This makes it particularly portable and suitable as a beginner's instrument for children. Normal trumpets bring about a large downward weight lever in children, which is difficult to stabilize in terms of force by those with straight arms, so that they tend to play the normal trumpet at an angle, which is bad for the construction of the attachment. This lever problem is eliminated by the pocket trumpet because the total weight is close to the body with a short lever.
The disadvantage is that the tube length on the first and especially the third valve - unlike conventional trumpets - cannot be changed while playing, which can lead to intonation problems.
The bell of pocket trumpets is much smaller than that of normal trumpets, has to become conical earlier on a shorter length, which affects the sound, and corresponds more to the length of the cornet . The valves are always pump valves , since rotary valves mechanically exclude such a compact design. The more frequent pipe windings caused by the compact design slightly increase the blowing resistance and allow condensation to develop more quickly due to air or breath moisture, so that when playing the trumpet, drainage must be more frequent than with normal trumpets.
