I use a Window of Tolerance model as a framework for understanding self-regulation. The term “Window of Tolerance” was coined by Dan Siegel (Siegel, 1999) to describe the zone of arousal in which we can handle stressors with relative ease and resilience. When we are operating within our window, it’s not that we don’t experience stress or elevated arousal but that, when we do, we have a feeling of “I’ve got this.” We are able to mobilize the energy and focus we need to complete the task or deal with the stressor in front of us — whether that’s giving a recital performance or simply working through a tough passage in a piece — and then quickly and smoothly return to a state of ease and equilibrium.
