How do you get your mouthpiece unstuck form a trumpet?

1. Apply heat to the mouthpiece. You can do this by running it under hot water or using a heat gun. Be careful not to apply too much heat, as this could damage the mouthpiece or the trumpet.

2. Gently tap the mouthpiece with a rubber mallet. This will help to loosen the seal between the mouthpiece and the trumpet.

3. Twist the mouthpiece back and forth. While applying heat, gently twist the mouthpiece back and forth. This will help to break the seal between the mouthpiece and the trumpet.

4. Pull the mouthpiece straight out. Once you have loosened the seal, pull the mouthpiece straight out. Be careful not to twist or turn the mouthpiece, as this could damage the trumpet.

5. Clean the mouthpiece and the trumpet. Once you have removed the mouthpiece, clean it and the trumpet with a soft cloth. This will help to remove any dirt or debris that may have been causing the mouthpiece to stick.

If you are still unable to remove the mouthpiece, you may need to take it to a professional instrument repair shop.
