Tori Amos taught herself to play piano at the age of 2, and started composing at the age of 3. She was admitted into the Peabody Conservatory at the age of 5, but lost the scholarship six years later, reportedly due to her dislike for using sheet music and interest in rock and pop music which the school did not approve of. https://en.m.wikipedia.org/wiki/Tori_Amos#Early_life_and_education
