Mrs Brown had no musical training when she was a child aside from a few piano lessons. Someone once claimed that maybe she had advanced musical training but then forgot it in a bad case of amnesia. This claim was said to be preposterous by the Brown's family doctor. Rosemary claims that those few piano lessons were the only musical training she has had.
Mrs Brown claimed that famous composers dictated work to her. In 1969 she was put to a test. She was put in front of a piano by British Broadcasting Company and waited for Liszt to appear. He came and dictated to her a piece that was too hard for her to play. Someone else who could play the piece was sent to play it. The piece was later investigated by a Franz Liszt expert, who said it had definite similarities to the great composer's work.
A recording of the music (The Rosemary Brown Piano Album) and various books by Mrs. Brown (Unfinished Symphony) were published.
