Check to see if the valves have been taken out and mixed up. At any rate, any of these water key problems are usually easily and quickly fixed.ģ. Check also to make sure that the water key spring is not broken or missing, and check to make sure that the water key is not bent, which would also prevent it from sealing completely. If a water key cork is missing or broken or otherwise not sealing well, then the result will be an airy or stuffy sound. This can be quickly and easily repaired by simply replacing the spacer bumpers.Ģ. If the valve is out of alignment due to missing or worn spacer-bumpers, the result will be a stuffy, almost half-valved type of sound.
(These spacer-bumpers are made of different materials on different brands and models of trumpets and other piston-valved brass instruments.) There are two of these on each valve: One on the outside of the instrument that makes the valve quieter when the valve is pressed down, AND one on the inside of the instrument that makes the valve quieter when the valve is released and pops back up.Ĭheck also to make sure that these felts/corks/spacer-bumpers are not worn too thin (a common problem with older instruments.) These bumpers not only make the valves quieter, but also act as spacers that make sure that the ports in the valves line up evenly with the valve slide ports. Check the valves to make sure that none of the felts/corks/synthetic-rubber spacer-bumpers on the valves are missing. Please help! I don't want to have to send this trumpet to a repair shop for something that might be an easy fix.Īssuming that you have already checked to make sure that each of the valve's valve-guide notches is locked in its place in the groove inside of its corresponding valve casing, there are five other possible causes of this problem:ġ. It almost sounds like the sound you get when you press down the valves halfway and play. All of the valves seem to be in place, and nothing seems to be broken. When I play it, I can hear the correct notes, but it sounds like the horn has a mute on it. I tried it myself, and it sounds like there is something misaligned. One of my trumpet students came to me with a problem with her instrument. My friend's original e-mail about this was:
I decided to post that response to him here, because I thought that other trumpet players and band directors might also find this information helpful when trying to solve problems with trumpets, cornets, and other valved brass instruments that are not working right and are getting a bad sound. A band director friend of mine recently e-mailed me and asked me about a problem that one of his students was having with their trumpet.
