"My suggestion would to play smart and NEVER shatter your lip. It would also be to get some good lipslur exercises like those by Earl Irons or Max Schlossberg. Long tones and lipslurs along with playing smart EVERY DAY generate a solid stable embouchure over time. It is evolution not revolution and instead of looking at ourselves, we concentrate on the task at hand: making music instead of posing for a beauty contest......."
Although I actually COULD win a beauty contest, it's because I collect amazing aloha shirts and wear them every chance I can get - but Rowuk is right, it doesn't have to do with trumpet playing - except it will help you pick up babes after the gig if you're single - which will relax you for the next gig
Listening to your playing I would say do this exercise: take simple lip slurs in eighth notes - low C to G below high C - and go up and down for 1 minute. Then go to 123 valve combo and do the same. Then 13, 23, 12, 1, 2. This is pretty taxing because it is 7 minutes of continuous playing. After a few weeks - go to low C to high C.. and then all 7 positions again for 7 minutes, 1 minute in each position: 0, 123, 13, 23, 12, 1, 2. Some call this exercise '7 in 7'. This will develop great endurance and range for you. Also, make sure you are playing a mouthpiece that is shallow enough and has a comfortable rim. Looking at the type of playing you are doing in the video I assume you do some outdoor playing and overall have to be producing some volume. A shallower mouthpiece for that type of playing you're illustrating will help. A recommend a Warburton 'SV' cup in your rim size for you as it is moderately shallow and should give you the sound you are working for. Make sure you're trumpet has middle of the road specs - meaning a ML bore would probably be best with a bell that is between 4 3/4 - 5 inches. Best of luck dude! Lex
p.s. - Irons and Schlossberg are fantastic staple books - it's just that the '7 and 7' exercise is particularly powerful and efficient because of how it works the chops. But you would do very well to work some Irons lip slur exercises and make sure you can play them quickly and easily with a good sound.
