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. G10 is out of the 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''.
