The Best Brass trumpet mouthpiece design features a solid, heavy cup and two shallow recesses cut into the cup as it tapers into the backbore. Between the heavy, resonant cup and the recesses, the mouthpiece achieves a highly manageable sensitivity for broad dynamic range and subtlety, along with a thick, colorful sound and the capacity for good volume and long carry. It is flexible, expressive, and powerful when you need it to be. It is like no other mouthpiece you've ever played. This is the TP-3C.

Best Brass trumpet mouthpieces have a rim width of 5.823mm with a flat rim contour, a rim top balance of 43% and a fairly sharp rim bite. If TP-5C is too small, the TP-3C is an excellent choice. Very popular and playable from orchestra to brass band, its rich and powerful sound has a great tonal core. It compares closely to the Bach 3C.
