Order your custom Marcus Bonna case through February for delivery in May. The (delayed) chaos tariffs don't include brass instruments or non-USA-made items, yay!
The C trumpet is used in orchestras and brass choirs. Many soloists choose the C trumpet for its agility and clear, centered toner. You can also read concert pitch parts with no transposition necessary. If you have a Bb trumpet and wish to branch out toward more classical playing, mastery of a C trumpet should be your next conquest.
