Natural trumpet
A brass instrument from the trumpet family that lacks valves or keys to change pitches. These instruments only produce the pitches that are contained in the natural overtone series. These "natural" instruments often have crooks, or alternate lengths of tubing that change the key of the instrument, or the inherent pitches that the instrument can play. Experiences players can also produce tones outside of the overtone series through lipping techniques.
