Do you remember your childhood friend, the one who knew the girl you fancied, the one who was the intermediary between you and “your heart’s desire,” who let you know if she was equally fond of you, and who passed messages and notes between the two of you? And do you remember when you asked one parent to “run interference” with the other, to shield you from the blow or scolding or grounding that you were afraid you would receive if your defender couldn’t soften the heart of the other? These were probably your first experiences with the role of an intermediary.
Putting these things in the terms of childhood memory will, I hope, help you to recall just how important that mediator was, how much you counted on her or him to put things right for you, how much dependency was involved, and how grateful you were if she was able to do the job of advocating for you efficiently and well.
As adults we still use these kinds of mediators, intermediaries, or advocates. Lawyers “make our case,” accountants talk to the IRS on our behalf, reference persons write letters or recommendations to potential employers or universities, agents negotiate salaries for us, and a marital therapist tries to help two people repair their relationship.
But the intermediaries whom we most esteem, I think, are those that perform a public form of intercession. I am speaking of musicians, actors, and clergymen.
What do I mean by this? Let’s start with musicians. They take the printed note on the page of music paper and give it life—sing it, play it, form it in the way that they understand the notation. The players interpret the music. It is said that they “recreate” it, but truly, it does not exist except as an abstraction until they begin to perform it; we do not hear it until they begin to “make” the music. They are the intermediaries between the composer (who might be long dead) and us.
So too, actors and actresses. They give life to the playwright’s or script writer’s words. These players shape the words, give them emphasis and color, drama and intensity. And they are the carriers of the playwright’s meaning, his advocates and his intermediaries in the communication he hopes to bring to us, the audience.
Clergymen and clergywomen serve much the same purpose, only with religious texts. If you believe that they serve a higher being, then you also believe that they mediate between God and man. Their sermons, if eloquently delivered, are no less moving than the sounds of stirring music or the voice that an actor gives to Shakespeare’s lines.
We esteem these mediators, in part, because (at their best) they reveal to us a higher, loftier, more intense and creatively imagined way of being; they move us to tears or to excitement or to hope; they quicken life, stimulate thought, open our hearts, teach us, and, if we are ready, change us.
Given the effect that they have on us, these mediators receive our appreciation and, sometimes, adulation. Indeed, because the composer or playwright or screen writer has given over the task of performance to these people (while he is in the shadows, even if alive), we can lose sight of the author of the creative work being presented to us on stage. And, so too, the recreative artist (the actor or musician) can get a bit too carried away with his own self-importance. Indeed, it is rare for the great conductors, singers, actors, violinists, and actresses of the world not to be at least a little full of themselves.
One who was not, however, is the subject of an excellent new biography: Serving Genius: Carlo Maria Giulini by Thomas Saler.

Giulini was an Italian symphony and opera conductor who lived from 1914 to 2005. His humility in the face of the geniuses he served, that is, the great composers, would have been for nothing if not for his own talent in giving life to their music. Giulini felt that his role was a small one, as the servant of these great men, as the mediator of something much bigger, more important, and more lasting than himself. Giulini was a man both great and good, an extraordinarily rare combination. I had the good luck to hear him perform dozens of times and to interview him once (and, in the interest of full disclosure, I was interviewed for Mr. Saler’s book).
Giulini took his role as the link between composer and listener very seriously; indeed, the responsibility to the composer, to do his art justice, was a weighty one to this enormously conscientious man. Giulini gave the concert that celebrated the liberation of Rome from fascist control in 1944 during World War II. Soon after, he was asked to play Bach’s Brandenburg Concertos, pieces he admired but did not feel ready to perform. Pressured to do so in a concert that was well received, Giulini nonetheless felt he had let down both the composer and the audience by playing these pieces before he was convinced of how to best recreate every note. It was 22 years before he finally felt that conviction and again conducted any work of Bach.
As quoted in the biography, Robert Marsh said of the conductor, “He is one of the most completely civilized men I have ever met, one who can command without every raising his voice, who wins and holds your loyalty by the nobility of his character. If music is to lead us to the fullest awareness of humanistic values, men such as Giulini will be the models we must follow.”
Intermediaries. They mean a great deal to us.
As you can tell, Giulini did to me.
