I hope the members of this forum can give me some advice. Neither my wife nor I are musicians, but our twelve-year old son, who has been playing about four years, has been called by one of his teachers â€œthe most naturally talented trumpet player Iâ€™ve seen in 25 years.â€ Weâ€™re at the point of buying him something to replace his beginnerâ€™s model (hoping to find something to take him through college, probably), and of course we are at a loss about where to begin, or what all the specifications mean, notwithstanding our research. He tends to be more interested in jazz ensembles than classical, if that matters, and heâ€™s a kid who likes to dance to his own drummer, if you know what I mean. Any advice would be most appreciated. His current school teacher has not been very helpful in explaining this all to us non-musicians, Iâ€™m afraid. So what about bore, reverse lead pipes, valve resistance, traditional vs. lightweight, one- vs. two-piece bells, bell sizes, brass types, finish, etc. should we be thinking of? Should we stretch him with a pro model, or take an intermediate step? What brands would be most appropriate? Is it wise to buy online? What about an older, used model? Mostly, of course, weâ€™re just interested in finding him the right trumpet while avoiding an expensive mistake. If the answer is â€œdonâ€™t worry so much, weâ€™d like to hear that too!â Thanks much.
