Joan Trimble (born in Enniskillen on June 18, 1915; died August 6, 2000) was an Irish composer and pianist.
She studied at the Trinity College, Dublin, the Royal Irish Academy of Music, and the Royal College of Music.[1]
She first gained notice as part of a duo with her sister Valerie. They debuted with "Jamaican Rumba", composed for them by Arthur Benjamin, which became a signature tune for the duo. Joan also composed Buttermilk Point and others for the duo. In 1957 her opera Blind Raftery became the first new opera to be broadcast on the BBC. After her father's death in 1967 she went to work on his newspaper and this slowed her composition work. She regained some attention when she was commissioned for a composition in 1990.[2]
