I have been playing trumpet for about three years, and i still have the same trumpet, it is a beginner bach. My tone is not really airy, but it sounds crappy, i practice about an hour a day and do long tones and everything, do you think it is possibbly ny trumpet or am I doing something wrong, or what! Please help me out.

first of all, its barely ever the trumpet, its all embuchure...

if u have braces, that could be affecting u but any other way, its the way ir holding ur mouth

remember:corners tight, and with the embuchure issues, just say M-E and ur lips should be were they are supposed to be

Air support from the diaphragm is necessary to achieve a good, full tone. Blow harder (greater air speed) to get more volume, blow fuller (more air volume) to get better tone.

Omar and Ray are right but it could bethe fact that u do practice and hour a day to. maybe you should makeit 30 minutes every once in a while because it may be the fact that your lips are tired by then.
