I've been playing trumpet for several years, but I think I've been tonguing the wrong way the whole time. I've always wondered why I couldn't tongue fast and why it sounds so wet and sloppy. When I tongue, I put it on my bottom lip and kinda between my teeth. I've tried tonguing with my tongue on the roof of my mouth, but it sounds like I can't articulate correctly. Can someone tell me the correct position for my tongue, and how to correctly do it?
