iv been told by my teacher that 3c is better
so what are the pros and cons?

also, i want to switch permanently to a 3c, so how do i do it? i know sounds stupid, but i duno how to switch. i keep getting air leeks from the 3c evry time i try to play n its really bugigng me. iv tried lots of buzzing-its bin nearly a month now.
how long will it take to adjusst?

don`t use your 7c just practice and perform on your 3c and it will come. I do it all the time between 3e and 3c

One way to switch is to put down the 7c and pick up a 3c. ;-)

if you don`t get a seal on your lips, then maybe a 3c isn`t for you. If your teacher is forcing it on you then perhaps your teacher isn`t so good. If 3c really was the best then all the pro`s would use it right? but they don`t. I like the 3c but there`s better. I would encourage you to shop around and try some.

Schilke had some good documents on mouthpeices but they are revamping a little bit.

Read this, even if you don`t buy a Schilke mouthpeice (which you have no reason not to they are great).

I have a Schilke 14a4a which helps give a "fast" feeling, with a tight backbore for helping you push up to the high notes, and a slightly contoured rim to help with endurance, but not so much as to keep my flexibility down. It does have a tendency to have an airy sound to it though that isn`t present with mouthpeices that don`t have such a tight bore, and a shallow cup. So I wouldn`t recomend that particular one.

Read the description of all the options so you get a good idea of where you want to be, and then go into your local super mega music store and see if they have some you can try. Maybe call up schilke and ask. Music123.com also has a money back policy, you might call them and ask if there is some method that you can try some mouthpeices out without getting stuck with 15 different ones you will never use.

well i suppose i do want to get used to the 3c i havnt touched my other one in ages.. how do u guys prevent the air leaks? how do u use a tighter seal? coz if its pressure im using way too much already...

A 3c??? Does that have an extremely deep cup?

Anyways, as far as eliminating mouth leaks, perhaps try practicing flexibility excersises.... i.e. - lip slurs. Do what you can with your current lip strength, then increase your range, as far as you can without air leaks. The previous replies were correct... completely eliminate the 7c... eventually your embochure has to adapt.

A 3c??? huh? Sorry, I`m familiar with Yamaha, and the higher the number, the shallower the cup... so perhaps it`s different with the model you are seeking. My current mouthpiece is a 14a4a Yamaha.

some months ago i changed from 7c to 3c. That was not so easy, but keep practising with 3c and not with the 7c and it will be ok. It takes some time, i know.
I did it.

also make sure you have the right emouchure. The lips should puff slightly which should help with leaks. try super-chops.com for more info.

There seems to be some confusion on mouthpiece sizes. First of all, for example the 3c from bach. The first thing is the number. This is the cup diameter. This is followed by a letter. This is the depth of the cup. As a rule the later in the alphabet the deeper the cup.

As for the air leak. Maybe the 3c isn`t for you. My advice is to go to a music store and try mouthpieces. No one mouthpiece is for everyone. I play on a Kelly 5c (same as Bach 5c). I love the endurance it gives me in the upper register.

I started playing cornet with a 3C mouthpiece when I was age 9 (49 years ago), but now play trumpet using a 7C for church music and concert band, and a 10 1/2C for jazz. You might ask your music teacher if the 3C recommendation is based upon his/her personal experience. The 3C may not be the ideal mouthpiece for you. That is going to depend on the size and shape of your embouchure. Ask if your teacher knows anyone who has a "mouthpiece kit" from which they can put together any combination of mouthpiece cup and shank. That`s how I found that the 10 1/2C works better for me in jazz applications. Good luck, and don`t let difficulty in finding the right mouthpiece discourage you from becoming an accomplished trumpet player. The more you play, the better you get, and the more you will enjoy it.

I know I"m going to sound like a broken record but ... *deep breath* music123.com has a mouthpeice program that lets you try up to 4 mouthpieces at time (each one you return does have a $3.50 stocking fee, which is acceptable when you figure they can no longer sell it as "new"). Try the gammit(sp?). Go try parduba, schilke, maybe jet tone. The key is, to figure out what fits you. It took Harry JAmes a long time to figure out that Parduba was the piece for him. People are constantly on the search for the right one. Maynard Ferguson switched to a Monette in the 90`s. After 50 or 60 years of playing! The 3C is a good all-around peice, but isn`t the end all be all. If it was there wouldn`t be others right?

I think if the 7 worked for you but you want to move on, maybe try a Parduba 4 or 5, maybe a Schilke 5 or 6a4a. If you really like Bach try out the 10.5C as someone else suggested. They key is to find what works for you.

hey guys
wow, i didnt expect this many replies

well..i decided that i do want to make the switch-for now anyway, and have been working on it for about 2 n a half weeks-lots of buzzing. ?I`m kinda getting used to the 3c but every now n again wen i try to play loud i think i lose control n get air leaks but its not as bad as before..
i think iv got a problem of pushing too hard. its a bad habit n i really want to stop it

I first played on 7c for a few years and then I tried 5V, which is very deep and gives incredibly smooth tone, but it just didn`t fit me at all. So recently I changed to 3c. It fits me a lot better than the other ones, it took me just a few days to get used to it

If you were one of my students that would be the first thing I say. It sounds like you push hard and blow hard. Blowing too hard can break the seal on any mouthpiece. Lip slurs are a good suggestion, as well as not going back and forth between mouthpieces until you can really control whats happening.

I play on a 3c sometimes, still. It has a great feel. I would echo, too, that if it doesn`t feel right over an extended period of time, it may not be the right mouthpiece (or just not the right time for a switch).

WHY??????????

i am a fine player with many good skills and qualities but the only problem is that i tire within such a short amount of playing..15minutes-even if i keep towads the lower register

please give some advice
