True Music, like all true Art, is an experience to be shared, not judged, for praise cannot make it better, as blame cannot make it worse

As an improviser you need to experience the moment- and that includes everything in the moment. Observe the people around you-the bandleader, the bartender-what they wear, how they deal with people, the simple continuity of their presence. As you do that you'll see how you affect them , and you'll play and act accordingly. You need to study the reality of the moment, and that is very rarely about studying modes and intervals.
