Hi there, i'm beginner in playing tumpet, can say its already two years....
I cant play the trumpet loudly, why?
And my sound is inside the bell, it cant come out, issit embroucher's prob.?

How can i play it loudly, but no broken sound?
And how i can play out a richer tone??

Try to get more air through the instrument, and don't forget that you are behind the sound as it emerges from the bell, and so this will always seem quiter to you...

Unless that is you play in front of a wall...

but how about richer tone?
how to say that is a rich tone? how is a dark tone? bright tone?
who got example for me??

Mouthpieces can help a bit, but for a warmer sound, get nire aur through your instrument and concentrate on keeping your embochure right. There really is no real substitute. I have a garbage embochure and I'm finding it out to my cost!

how is a better embouchure?
a right embouchure?

In my teaching I've noticed that people's sound seems to deteriorate when they are concentrating on reading the music. Maybe if you try getting yourself away from the music stand and just play something really simple from memory, so you can devote all your attention to your breathing and projection. Try this: before you play a note, prepare yourself. Take a deep breath, hold it, and then exhale. Do this several times until you feel really relaxed. Then just blow some random long notes. Don't try to go too high. Imagine you are playing to the houses over the road, and not within the confines of your own room. How much long note practice do you do? If you just do 5 minutes of long, low notes as a warm-up each time you practise, you should start to hear a difference in tone and your ability to project in a few weeks' time.

then how to perform a long, powerful high note?
its needed in my band jz right now...
and second, i need to play it fast. like touging n fingering mz be fast, how to practise it?

and who can tell me wat a 30 minute practise per day need to do? to get a effective result..

Do you have a teacher? What does he/she say you should do?
If you don't have a teacher, it would help you to get a couple of lessons at least, so that someone can actually see you play and therefore diagnose the "problem" - if there is a problem - and propose a structured practice plan for you. Unfortunately, there is usually no magic quick-fix solution to anything in brass playing - it all takes time and persistence. I'm speaking as a post grade 8 player of almost 30 years' experience.

i have a teacher, but jz took 1 lesson.
he said my air not balance, so it got unbalance vibrate
n he gave me a study, a varios scale....
how ur comment?

Nothing to add to my advice about long notes.
Try lots of long notes every day - if it doesn't help, then you certainly won't be any worse off.
(one lesson in 2 years isn't much really ...... go on, treat yourself to another one !!)
Best wishes,

hi!! i'm back..
i'm going well now..
jz, when i play wif my band, i found tat my sound really really odd.. its discusting..... i wonder y,

probable said already

sit up straight
dont cross your legs
dont press hard against the mouthpeice
when you breathe imagine you are filling your lungs up from the bottom
kepp your shoulders level
make shure you use lots of air when you blow
tighten your lips at the corners (good book for this is "How brass players do it")
imagine you are pushing the air down your trumpet and that you are making an sound come right - not so it sits in the bell but so it flys away like a gun shot
