Feeling Jazzy: What Improvisation Does to the Brain

Jazz musicians experience a state of intense focus and effortless creativity known as “flow” during solos. Using fMRI techniques, researchers found increased activity in the brain’s Default Mode Network (DMN), associated with self-expression and idea generation, and decreased activity in the Executive Control Network (ECN), linked to idea monitoring and evaluation. This suggests that jazz improvisation involves decreased inhibition and increased mind-wandering, reflecting a state of flow. Achieving this state requires practice, technical mastery, and the willingness to take creative risks without excessive self-censoring.
