The Philadelphia Orchestra has hired a new tuba player. Who is twenty years old. And female. And if you think that’s not a major departure from the orchestral norm, you clearly haven’t spent much time scanning the low brass rosters of prominent ensembles. Still, “if brass players have a reputation for macho banter and a certain amount of antics, Carol Jantsch should have no trouble keeping up. She once won a tuba-throwing contest at a tuba conference in Finland, casting an old instrument into a lake, landing first prize in the women’s division.”
