My cousin is looking to get her 8th grade daughter (a quiet, polite young lady who enjoys playing) a nicer trumpet than her current beginner student model. I don't know what she's playing now but given that it's a rental I'm not expecting much out of it.
I don't know anything about trumpets (and told her as much

) but suggested a used pro horn might be the best bet, with the current horn kept as a marching/pep band horn. Probably a relatively hard cap of $700, I plan on helping out to get her a good horn. She'd likely use this for concert band and jazz. I think a lighter horn would be a better fit for a younger player, sonically and physically, maybe a mid-lightweight symphonic trumpet...? Aren't trumpets categorized something like that?
I also suggested perhaps a year of private lessons on the current horn with an eye to upgrade after that.
Any suggestions?
