In the 1970s, less than 5% of musicians in the top five U.S. orchestras were women, whereas now that percentage exceeds 30%. A key reason for the change is that, in the1970s, orchestras began using blind auditions where candidates, with their names and backgrounds withheld, play for juries from behind a screen.
