Story telling. Not taught so much any longer, but used to be a thing.
So, one of my early mentors was a pianist in whose band I played several times a week. Often we would be rehearsing one of his new tunes and he would comment on my solos. More than once he said some version of "Yeah, I hear that you're playing all the right notes and the changes, but I need to you tell a story. I need your phrases to make sense and mean something."
It was a thing. Your statements as a player were expected to sound meaningful and progress in a way that made sense.
