Incredible footage shows a teenage girl singing her way through brain surgery in order for doctors to preserve her musical talent.

Kira Laconetti, 19, a self-taught musician, began experiencing difficulty when singing or listening to music, having two-minute 'glitches' and stuttering her words. 

An MRI scan on the performer from Lynden, Washington, revealed a marble-sized mass in the right temporal lobe of her brain. The benign tumour was confirmed to be triggering a rare disorder called musicogenic epilepsy.

The condition, which is estimated to affect one in ten million people, according to Epilepsy Society, triggers seizures caused by certain types of music or frequencies of pitch for which the person's brain has a low tolerance for. It is unclear what specific notes or music prompted Miss Laconetti's seizures.

Surgeons removed the teenager's tumour while she was belting her favourite songs and belting out one of her favourite songs, Weezer's 'Island in the Sun'. The approach allowed them to identify and therefore avoid the areas of the brain she uses when she sings.
