How to Remove a Stuck Trumpet Mouthpiece

How To Remove A Stuck Trumpet Mouthpiece

Mouthpieces on trumpets and other brass instruments can often get stuck. It is quite easily done. All it takes is to accidentally knock your instrument by the mouthpiece and it could get completely jammed in. This is why you shouldn't pat the mouthpiece into the trumpet. Though it does give a saitisfying sound you could get your mouthpiece stuck. The real pain about getting your mouthpiece stuck is that your trumpet, or brass instrument, will not fit in it's case properly.

Don't Use Pliers To Remove The Mouthpiece.

Above is a picture of a mouthpiece from a trumpet I had to repair. It was stuck and somebody removed it with a pair of pliers. Mouthpieces are made of brass, which is a soft metal, and you can see the deep scratches which the pliers left. This mouthpiece was worth £40 new and now it's ruined. When you twist the mouthpiece out with a pair of pliers you could also could damage the trumpet in the process. The trumpet which this mouthpiece was stuck in became slightly twisted under the tension of the pliers. A solder joint had been forced loose and the valves jammed after the pipes had been twisted into the the valve casing. I managed to fix this trumpet successfully but it would have been much easier and cheaper to remove the mouthpiece properly in the first place.

Remove Your Mouthpiece

If your mouthpiece gets stuck you could try to remove it by hand first. I find that if you give the mouthpiece a tug and twist at the same time it can often come free. You have to be careful not to use too much pressure as you don't want to damage your trumpet. You could try some penetrating oil where the mouthpiece enters the trumpet and some hot and cold water. Sometimes giving the mouthpiece receiver (the part of the trumpet that the mouthpiece goes in) lots of small taps with a rawhide mallet can help loosen it.You could also try pulling the mouthpiece out with a rope giving it several pulls and jolts. If all that fails, some music shops or teachers will have a mouthpiece puller and will remove it for you for a minimal fee. I suggest you watch the short video clip below as I will show you some of these techniques.

In this video I will show you different ways to remove your stuck trumpet mouthpiece. This will include by hand, hot and cold, tapping with a mallet, pulling with a rope and using a mouthpiece puller.

Using A Mouthpiece Puller

Using a mouthpice puller is quite easy and it is a very useful tool to own especially if you teach or conduct a band. Kids, and sometimes adults, are always getting there mouthpiece stuck and this is the tool for the job! As you can see from the picture above the mouthpiece slots into the puller which has two adjustable "teeth" which can be tightened to grip against the "lip" of mouthpiece receiver. You then tighten the two large screws clockwise to start pulling the mouthpiece out. It is important that you tighten these screws as evenly as possible or the mouthpiece puller itself could become jammed or cross threaded. I've always been able to remove a stuck mouthpiece with my puller, and I have removed a lot! On the stubborn ones I give the puller a tap with a rawhide mallet to help the mouthpiece out while the puller is under tension. I am then able to turn the scews on the puller a little more, and then repeat until the mouthpiece pops out.

      How interesting, that there is a special tool to use for a stuck trumpet mouthpiece! I'd never have thought it. But your explanation does make it very clear that pliers are not a good substitute!
