Note in the article I quoted above that her range was stated to be almost 4 octaves. Her mother is a coloratura soprano. We are born with vocal folds and potential that determines our singing range. She apparently inherited her mother's coloratura range (being a flexible and agile voice and the ability to sing the highest notes). Being raised by a mom who was a vocal coach for her from an early age, she did have the ability (and inborn gift) to be a professional singer at the young age she started recording. The problem is, it seems maturity to handle that kind of career pressure is not what she has.
