This short clip of Keith Jarrett improvising on ‘I Love You,’ embodies ‘letting go.’ Jarrett is an American classical and jazz pianist who says his best performances happen when he has no idea what he’s going to play the next moment. “The only thing that works” Jarrett says while improvising is “letting go.”
According to Charles Limb MD a surgeon, neuroscientist, and musician at the University of California, San Francisco (UCSF) “…research shows that the brain is shutting down your inhibitions during these creative moments. It appears that to be really creative, you need to avoid critiquing and controlling your actions, and instead, let yourself go in order to get into the moment, regardless of any mistakes….turning off monitoring.” (https://www.ted.com/talks/charles_limb_your_brain_on_improv)
When doing the 'practice of immediacy' you let go by including what’s occurring within and without: sounds, critical thoughts, sensations, cars going by, feelings, the toilet flushing, self-monitoring thoughts…. By staying with the 'practice of immediacy' creative flow can emerge. Go to the link https://practiceofimmediacy.com/videos to see this in action using acrylic paints and oil pastels.
