C3 & C4 Mouthpieces for Bb trumpet

Prana Resonance & Classic Resonance (standard-weight & lightweight)


Rim Size Comparison: Conventional 1-1/2C, Schilke 16, and other similar rim sizes


The C3/C4 size range is very much a 'middle of the road' rim size, and a great option for former 3C, 5C, or 7C players who would like a bigger sound.


C3 and C4 rim options vary in rim contour:

  • C3 Rim: Feels a bit smaller than the C4 options, similar to the size of a conventional 2C


  • C3F Rim: This was a custom rim design with a fairly flat rim contour, hence the letter F in the name


  • C4 Rim: The original B4 rim design is somewhat flat, with a fairly sharp bite. Many players will prefer the softer-feeling B4S rim instead.


  • C4S Rim: Originally created for our friend Lew Soloff, hence the letter S in the name. Although sized like other B4 mouthpieces, this rim design was based on Lew's favorite vintage 3C


  • C4L Rim: Lead mouthpieces in this rim size have a bit more cushion on the rim for extra comfort with demanding high-note playing

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



  • C trumpet mouthpieces are usually made in the standard-weight Resonance body.
  • If you prefer the lighter-weight Resonance LT body for a brighter sound and/or lighter feel, just add a note to your order during checkout.


Plating & Finish:

Classic mouthpieces have a shiny, buffed 24k gold finish

Prana mouthpieces have a brushed 24k gold finish

  • Monette mouthpieces are made-to-order and usually will not be available as ready-made stock. The standard estimated wait time to have a trumpet mouthpiece made is approximately 6-8 weeks. Less common sizes are likely to involve a longer wait time. The exact wait time is unpredictable, as it is affected by many variables. We cannot guarantee a completion date or shipping date in advance. Thank you very much for your patience while you are waiting.
