"Aha!"
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.
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.
