How to Troubleshoot a Trumpet

The trumpet is one of the classic brass instruments. Its versatile sound is used in every genre from jazz to funk to classical. Learning to play the trumpet is challenging and enjoyable, but knowing how to troubleshoot a trumpet when something goes wrong is just as important as knowing how to play.

Instructions

Difficulty: Moderately Easy

1. Inspect both ends of the mouthpiece for nicks or scratches and clean out the inside of the mouthpiece with a brush to scrub out any dirt or debris.
2. Check the oil. Oiling the trumpet valves regularly makes it easier for them to move up and down and improves the trumpet's tone. Unscrew and pull out each valve individually and make sure it's well-oiled and working properly.
3. Grease the slides. The slides affect the sharpness of the trumpet's sound and must be greased often to keep them moving freely.
4. Look in the bell, using a flashlight if necessary, and make sure nothing is stuck. If there is anything obstructing the main airway between the mouthpiece and the bell, the trumpet won't play. If you have to remove anything from the bell of the trumpet, do so slowly and carefully to avoid damaging the inside of the instrument.

Tips & Warnings

• If your trumpet isn't playing correctly, check to make sure that the slides aren't pushed all the way in. The trumpet will not play properly if the slides are pushed all the way in or if either of the valves is missing.
