@ssmith1226 said in Difference between trumpet and cornet:
@j-jericho
Trumpet- Cylindrical Bore
Cornet- Conical Bore
The ratio of conical to cylindrical tubing is about the same in a typical cornet and typical trumpet. What makes the difference is the rate of flare in the conical parts. A good cornet should have a more pronounced flare in the conical areas.
