Nellie Melba
From Tardis Wiki, the free Doctor Who reference
Dame Nellie Melba was an Australian opera singer. In the 1920s, the Fourth Doctor met her and learned her party trick of shattering glass with a high-pitched note. He used it on Delta III to shatter a window, allowing rain to dampen vines constricting him, Romana I and Rohm-Dutt. (TV: The Power of Kroll)
