Georgia Brown (Brazilian singer)
From Wikipedia, the free encyclopedia
Georgia Brown is a Brazilian pop singer notable for her extensive vocal range. She is the current Guinness World Records holder for singing the highest recorded vocal note and also possessing the largest recorded vocal range, which spans exactly 8 octaves from G2-G10. The G10 is out of human hearing range; thus, it has been verified by comparing the frequency of the note to that of a piano, a violin, and a hammond organ, according to the The Guinness Book of World Records.
She is not the Georgia Brown who played Nancy in the Broadway and original London productions of Oliver!.
