DS aged 10 plays trumpet as a second instrument, but has expressed an interest in switching to French Horn. is this a good idea? He just likes the look of the horn. He's about to take grade 2 trumpet. I don't play either so not sure whether to encourage this or not. Seems to me horn is rarer so he may stand a greater chance of scholarships/ entry into an orchestra when he's older, but trumpet is possibly more versatile; i.e. you can play it in an orchestra, marching band, jazz group etc. Any ideas?
