Lip trills on the trombone

Hello, my name is Denson Paul Pollard and I'm recording this video to answer some questions that I've received via email about trills on the trombone, lip trills, which are kind of fun and required in many solos on the trombone. In my opinion, a lip trill is really just a fast slur and anybody that's tried to lip trill on the trombone knows that they're easier when you're playing smaller intervals. A perfect fifth lip trill is difficult, but a major second is easy. So, it's better to try to trill on intervals that are smaller and oftentimes you can find those intervals that are smaller in the higher range. It's kind of easier to lip trill in the higher range. Now, how do you work on lip trills? How do you develop them? I would suggest, like most things on the trombone, you start slow. Move slow and gradually increase the speed. You can see in my face there's not a lot of extra movement. My face is pretty relaxed and you can also maybe see that my jaw is moving a little bit. I'm kind of doing that a little bit when I slur. If you have to do a slur that requires that your slide move, start the movement slow and then fast and then stop the movement in the middle, but keep the trill going. Above all, blow lots of air and try to stay as physically relaxed as possible when you're working on your lip trills. Have fun!
