Hello I'm in the 7th grade and started beginner band this year. I've some experience with music from piano and guitar. My band director is making a new jazz band in the spring and I'd like to join FYI I'm coming along real fast. I asked him about it and he said he never had a euphonium in a jazz band. So I thought about trying trombone to get in but I didn't want to have to have to learn slide positions I wanted to keep the valves. I also wanted to stay in the bass clef and didn't want to play tuba. So I'm wondering if there's any instrument I could play that sounds like a trombone but has valves?
