They anointed themselves the “most accessible orchestra on the planet,” and have gone some ways toward justifying that superlative. Tickets are cheaper than at other orchestras; my press seat, on the left orchestra aisle, would have cost twenty-five dollars. Neighborhood concerts reach into underserved communities. Most strikingly, the Detroit offers free Webcasts of its concerts—an initiative that seems obvious but that few other orchestras have tried. Anne Parsons, the Detroit’s president and C.E.O., told me, “We’ve gone from three thousand viewers on average to around seventy-five hundred—in one case, thirty-five thousand. It’s brought great young musicians to us—they can see what we’re doing. I was sure that, by now, everyone else would be doing it. I’ve stopped wondering and haven’t looked back.”
