u/Eunapius

I have recently been playing a lot of trombone when I don't normally (primarily a euphonium player) and I've noticed that I tend to get condensation dripping out of the bell after I've been playing for a little bit and I don't see that happening with the other trombonists I'm playing with. How normal is that to happen, and should I change something in how I play to help prevent it? It's mostly annoying to have it dripping on my leg but I wonder if I'm overblowing the horn and need to learn to play using less air...
