Welcome to this day to day sharing of insights into music. My thoughts and my playing reflect my lifelong drive to integrate primary reactions to sounds with a sense of playfulness open to lyricism as to intellectual game-playing - the level of musical response endangered if not already extinct due to the endemic compilations of sameness that make up our soundworld.
Perhaps that's it: What Kurt Andersen calls an "Aha moment." It is the rose being looked at/seen, the in-tune fifth sung/heard. Call it the transaction between stimulus and response.
