This article examines the spiritual dimension of jazz performance by looking at first-person accounts of improvising musicians and locating their experiential descriptions within a spiritual framework. The spiritual context is here defined as the realm of invisible processes that support and underpin the visible and auditory dimensions of improvised music. By collating evidence through first-person accounts, a series of themes emerge (wonderment, force, inspiration, letting go, happening, connection, being yourself, meaning and staying in the present), which, when seen as parts of a holistic process, can provide important components that are often missed in jazz education and jazz performance.
