Another lip exercise is to place a pencil in between your lips and hold it out in front of you. Do this daily and try to keep it in position for 3 to 4 minutes.
A lip slur is an exercise, often used by brass players, that involves creating and changing notes by using your lips alone. These exercises are often played in descending order and by notes with the same fingering. For example; G-C-G, F sharp-B-F sharp, F-B flat-F, and so on. . .
You can also get a stopwatch and time how long it takes for you to release 2 beats worth of air. See if you can extend this time with practice.
Try playing while looking into a full-length mirror. This will let you check your posture while you play. Always keep your shoulders back and your trumpet between parallel and 1 degrees above.
The opposite of this approach is lowering the tongue and making an “ah” sound.
