Rotary Valve Trumpets


The rotary valve trumpet is constructed with a valve body with two channels. When the valve is operated, the valve body rotates 90 degrees. After the rotation, the valve loop and the main pipe open into the housing at the same height. The trumpet with pump valves has prevailed over the rotary valve trumpet in jazz worldwide. It allows the typical squeakers and the tremolo. Bound passages and corresponding phrasing can be created more easily with pump valves. An effect that is frowned upon in classical music, but is absolutely desirable in jazzy and contemporary music styles. Instruments with rotary valves are supposedly more useful for beginners because you simply can't break something so quickly. Since with Périnet valves you must ensure that your fingers are correctly positioned on a straight axis, as otherwise they can tilt.
