A booster for trumpet mouthpieces, also known as a resonator, is an additional accessory that can help a trumpeter improve the sound of their trumpet. It attaches to the trumpet mouthpiece and can help enhance the tonal quality of the trumpet, add new overtones, and enrich its sound.
One of the main advantages of using a booster for trumpet mouthpieces is that it can help a trumpeter improve intonation and accuracy in hitting notes, which is especially important when playing in large ensembles. Additionally, using a booster can make the sound of the trumpet more expressive, which can be useful for solo performances.
It is important to note that using a booster for the mouthpiece can alter the sound and playing of the trumpeter, so it should be used with caution and only after careful practice of technique and sound.
