These are the best mouthpieces for lead and commercial trumpet playing that we have ever made! These new mouthpieces have been 35 years in the making... and we are thrilled with them in every way.

Info about the new Resonance XLT

  • The brightest-sounding, lightest-weight Monette mouthpiece for Bb trumpet

  • Freedom without constriction as you ascend, not just above the staff but into the extreme upper register

  • Fat, booming low register to match the effortless upper register

  • Same evenness of response and fluid note connections that all Monette Resonance mouthpieces are known for

  • Feels very secure in all registers in spite of its very light weight

  • Extremely easy to hear up close as you play - even in dead acoustic spaces

  • Excellent projection in large rooms

Patrick Hession loves the new Resonance XLT!



Our #1 most popular small-diameter lead mouthpiece, designed for Maynard Ferguson.

Considered comparable in size to the 13A4a.


The original Monette lead mouthpiece size.

Great for 3C players who want a lead mouthpiece with a diameter just slightly smaller than their 3C.

Great for players who like a diameter similar to a 7C.

Considered comparable in size to the 14A4a.

BL4 S6

The smallest and shallowest option, designed for Patrick Hession.

Considered comparable in size to the 11A.

B6 S1

The largest and deepest of the four sizes. The B6 S1 is a very popular size for all-around playing,

and great for players who prefer a lead mouthpiece with more room in the cup.

Considered comparable in size to the 3C and 5C.

Every rim and cup size beyond these four will require development time and prototypes to be approved, so there will be a waiting list for any other sizes. Just contact our shop to get on the list. 

Available in the Prana configuration only

Plated in either brushed 24k gold or bright silver

Big, fat low register to match the easy upper register!
