It is unlikely participating in Drum and Bugle Corps will negatively impact your concert playing. (At least not in The Rocketeers!) You should be able to use the same mouthpiece as your concert instrument. The playing techniques we focus on easily translate to becoming a better brass player and musician indoors. You should generally find that you will end up with more endurance and play with a stronger, more supported and darker sound. Part of our mission is to help you become a better musician.
