A Welsh woman broke the Guinness World Record for the lowest vocal note sung by a female singer. Helen Leahey, nicknamed the "Bass Queen," sang from a D5 to a D2 note at 72.5 hertz, beating the previous record, which was set by a woman who sang E2 at 82.4 hertz. Leahey attempted the record breaking note while being measured by multiple pieces of equipment at the Music School Wagnet in Koblenz.
