Material - Plastic cornet tops can be made in either Delrin or Acrylic plastic. Here is a comparison of their characteristics:

Feels softer on the chops because it has more give than metal. This is a great advantage for players with braces.
Not as slippery as silver, giving more grip.
Added grip makes Delrin mouthpieces feel smaller than their metal counterparts with the same size designation.
Not as smooth as metal, so some players may feel slight chop irritation for the first day or two while they adjust.
More comfortable to play in cold weather because they feel warm on the chops.
Plastic mouthpieces are more responsive than brass, making soft entries more secure.
Articulation less crisp with less point at the front of the note compared to brass.
Darker sound than brass.
Less core in the sound compared to brass. Sounds darker than brass mouthpiece when used with brass or stainless steel backbore.

Feels softer than brass but less soft and Delrin on the chops.
Less slippery than metal but more slippery than Delrin.
Grip intermediate between Delrin and silver.
Feel slightly smaller than the metal counterparts.
Smoother than Delrin, very similar to silver.
Comfortable to play in cold weather.
Responsive to soft articulation.
Articulation is clearer than Delrin, very similar to metal.
Sound is slightly darker than brass and brighter than Delrin.
More core in the sound than Delrin, but not as much core as metal.
Sounds very similar to brass when used with brass or stainless steel backbore.

Cup Depths

Regular cornet top depth similar to Wick B cup

Wedge trumpet tops can also be used for shallower cornet cup options and for piccolo trumpet

Throat Size

#27 (.144 inch) is the standard throat size for most mouthpieces, this is the best choice for most players.

#25 (.1495 inch) is a slightly larger throat for a more open blow. Choose a #25 throat if your mouthpiece feels stuffy with too much resistance and you are an advanced player with good breath support.


Cornet backbores are available in small, medium, medium large, and large. They are silver plated brass. The backbore throat size will match the top throat size you have.
