No question the YouTube Symphony Orchestra is geared toward the hope that kids can learn to love Brahms just as much as Beyoncé. But is it wise to allow an orchestra to be selected by those accustomed to posting about pet tricks? How, after all, can an audience raised on Auto-Tune vocal enhancement and digital sampling be expected to tell one violinist’s pizzicato technique from another’s? Won’t “American Idol” standards prevail, saddling the YouTube Symphony with musicians who have questionable pitch but really awesome hair?
