Arts in Health projects are growing in number in the UK. One such project, Singing Medicine (SM), is offered to children with short and long-term health care needs at a Children’s Hospital in England as part of the Hospital’s Play Department. In an environment where children can experience loss of control over decisions and restricted play experiences, musical games and activities offer children affordances  for choice and agency. They can also benefit parents and wider family members. In contrast to previous quantitative studies that explored the transferrable benefits of music participation for children, this paper reports on a qualitative study involving semi-structured interviews with families of children with long-term health care needs (ages 3 – 14 years old).
