When playing music, we get immediate feedback about our thoughts and emotions. We immediately understand the consequence of holding on to a “mistake.” (I don’t like using a strong word like mistake but for the sake of discussion let's define mistake as an unintended action.) We understand the importance of simply observing that “mistake” and not attaching to it, not giving it any energy good or bad. We learn how to listen. We learn how to work together and how the abandonment of ego/future and past images created by thought, is essential to the purest outcome. All of these are fundamental lessons when applied to any area of life.
