By the time she was eleven years old she could play violin, piano, tin whistle and uilleann pipes. During her teenage years she learned to play in both the classical and traditional musical traditions. She won several All-Ireland titles for fiddle and traditional singing culminating in the award to her in 1972 for the best all-round performer.
