The Lived Experience of No Longer Being Able to Play a Musical Instrument Due to Physical Impairments: A Heuristic Study

open access: yesThe Journal of Humanistic Counseling, Volume 64, Issue 2, Page 143-157, July 2025.
ABSTRACT For musicians, injury or illness can mean not only the loss of performance opportunities but also the end of a lifetime's calling. What is it like to face such a profound change? This study explores the lived experience of musicians who could no longer play their instruments due to a physical impairment.
