If your teacher asks how long you've practiced it obviously meant it was bad - if you had an amazing performance s/he would have assumed you've practiced a lot and wouldn't need to ask. But whether or not OP should be flamed for trying to show off - it's still an FML for being told that s/he sucks after 30 hours of practice on just one piece. That's a blow, OP seems to be not so musically gifted, but perhaps OP just needs more private lessons. Good luck! and hahaha, #48 just proved what douches trumpets can be, especially with the "signed".

Your own fault for acting trying to brag.

Someone just got force-fed a slice of humble pie.

If you practiced for 30 hours (which is probably a lie in itself) and don't sound like it, you were probably practicing wrong. Hell, if you have to practice any one section (which is what I'm assuming) for more than two or three hours, then you probably can't play your instrument very well in the first place. In addition to this, I agree with everyone who has said that saying you practiced 30 minutes was a stupid idea. Also I'm going to go ahead and say that trumpets are my least favorite instrument ever because of the sound that they make. But people like 48 certainly don't help.

Haha #3. She made a grammer error. Oh jesus that is funny...

That's why u shouldn't show off

YDI for not lying well

you aren't practicing right, probably because you're focusing on perfection and not musicality (and judging by how much time you spent... probably not focusing on detail the right way either). what you do is play through the technical stuff until you have a muscle memory built up and you don't need to think about the notes (DON'T waste time playing the stuff you already can do). THEN you focus on musicality. music isn't a science, you can't get 100%, there's always room for improvement. So when you aren't trying to improve what is your teacher SUPPOSED to grade you on?

u suck!!!!

dont showoff. they know
