I'm confused... Granpa's private teacher wants him to get a better horn and he has played one year and is going into the sixth grade? Sorry, I seem to be missing something or grandpa must be a very slow learner if he is in the 6th grade... I am kind of assuming it is grandson's private teacher... and if that is the case then I have to wonder what is wrong with the current trumpet... slides aren't typically even used by kids until they have been playing for a 2 or 3 years and then it is normally only the third valve slide they start using and then maybe in high school they get to where they need and use a first valve slide... And if the kid is still playing in high school I would probably be thinking it was time to move to a higher level horn. I hope the private teacher isn't offering to order the instrument for him or hasn't suggested he go to a specific store to get the horn.... I only say that because some people will buy horns for students and make a bit a money on the deal, others will feed customers to music store and get a kickback from the store from the sale... Lastly he is only playing for 1 year... so getting a new intermediate horn is kind of silly. I would suggest a good used horn is a much better option, even if it has dings and scratches it would be capable of working as a first horn and first time players don't tend to take very good care of their horns so those dings and dents they put on a used horn don't hurt nearly as much as on a new one.
