Welcome to TWC, Aimee! It's always great to meet other people who play the not-so-standard instruments for worship teams. I play trumpet, but I'm not yet part of a team. My husband plays guitar and bass for the worship team, and he's been working with me on how to play by ear using my trumpet. It's a SLOW process for sure, and sometimes I wish I had an outlet to help encourage my trumpet playing. In the Lord's time. :-)
Anyways, thanks for jumping into our forums so quickly! I'm sure you have a treasure trove of insight you can provide the members here. Be blessed!
