I think if many of us are honest with ourselves we will admit that our listening skills have not been given proper attention in their development. Most of us have practiced playing much much more than we have practiced listening. This is a major oversight and I am amazed at how this critical skill is so neglected by the great majority of musicians. The good news is that since these skills are so underdeveloped by most we have an opportunity for huge improvement quickly and relatively easily. No matter what level of musician we are we can make a big improvement in ourselves as musicians and people if we improve our listening ability.
