Mouthpieces for D trumpet are made in the modern Resonance body design. (Although not recommended, these can also be made in the vintage-model STC-1 mouthpiece body as a special order. Just contact the shop or add a note during checkout.)
 
Classic & Prana Internal Configurations
Prana mouthpieces allow for the most resonant sound, most effortless playing, and most consistent pitch and timbre
Classic mouthpieces can feel more forgiving for players who tend to play with a tighter physical approach, or who are accustomed to a non-Monette mouthpiece
