Leaders don't matter. That might seem hard to believe. Any large group needs a leader to function, right? How good can an orchestra be without a conductor? From Zubin Mehta to Leonard Bernstein, great conductors seem an integral component of great classical music. Someone needs to make sure the woodwinds don't come in too early and the percussionists don't drown everyone else out. The Orpheus Chamber Orchestra, though, has received multiple Grammies and is regarded as one of the finest orchestras in the world — without a conductor. It turns out that professional musicians can organize themselves without a formal leader just fine.
