i agree with jameh - "But can someone explain to me what the different notes are called? like for example, the C with one ledger line above the staff is a high C but what about the G under it? is it a high G? and the G above it is a double high G? please explain!!"

Try using a Vincent Bach 12c month piece. The smaller cup size the higher you will go. I've used a 12c for the last 15 years and it really works. But I use it for all note play and nothing else.

Oh Yeah I almost forgot. With that mouth piece I have successfully hit the tripple G with it but it does take alot of practice and breath control

Ok ummm lip slurs... anyone want to give me a hint as to what exactly these lip slur excersizes are? I know it's slurring and yeah, but like, more.

lets see well what i would is lip slurs. if you can get good at one octive and work your way up you should get higher.
and to get the dub G out with a good sound work on your low notes

Slurs are nothing fancy, you just slur from one not to another, the larger the jump the harder they tend to be and the more you do the quicker you lips get tired. They're a really good endurance/strength builder.

"i forgot to add this.
RIP Maynard Ferguson
any Maynard fans outthere?"
Totally yes!!! It's too bad but my advice is to tighten your lips. AND PRACTICE in the upper register. I include higher notes in my lip slurs. It helps a lot. A better trumpet and mouthpiece won't hurt either.

Breath control too.

"what are lip slurs?" Well, those are pretty simple. If u have a band director and u don't know, ur band books have got to be pretty bad. Anyways, lip slurs are just exercises in which you slur your way up and down on dif valves. for instance, play a g then up to c and back down for a few times . . . SLURRED!! the press first valve and do the same, f to b flat and down again ... the best valve order is none, 2nd, 1st, 1st and 2nd, 2nd and 3rd, 1st and 3rd, and lastly, 1st and 2nd and 3rd. Hope that helps!
