A musical term most often associated with jazz. But applies to photography, art and life.
"In music, the pocket isn’t a place where the musician holds something — it’s an intangible place that holds the musician. While this sounds a bit odd, the closest thing that I can think of to describe it is a spiritual experience that goes beyond playing the right notes, great timing, or being in tune. The experience of playing in the pocket is more like becoming a faucet through which the music flows. Being in the pocket is not just about “locking together” or “syncing up” as a band. It goes beyond this to the place where the musician allows the music to take control. "
