We are not obliged to agree with Proust’s actual musical descriptions (they are too pictorial for my own taste): but what we must admire is his use of rhythm in literature, and his use of something which is akin by nature to the effect it has to produce—namely a musical phrase. Heard by various people—first by Swann, then by the hero—the phrase of Vinteuil is not tethered; it is not a banner such as we find George Meredith using—a double-blossomed cherry tree to accompany Clara Middleton, a yacht in smooth waters for Cecilia Halkett. A banner can only reappear, rhythm can develop, and the little phrase has a life of its own, unconnected with the lives of its auditors, as with the life of the man who composed it. It is almost an actor, but not quite, and that “not quite” means that its power has gone towards stitching Proust’s book together from the inside, and towards the establishment of beauty and the ravishing of the reader’s memory. There are times when the little phrase—from its gloomy inception, through the sonata into the sextet—means everything to the reader. There are times when it means nothing and is forgotten, and this seems to me the function of rhythm in fiction; not to be there all the time like a pattern, but by its lovely waxing and waning to fill us with surprise and freshness and hope.
Done badly, rhythm is most boring, it hardens into a symbol and instead of carrying us on it trips us up. With exasperation we find that Galsworthy’s spaniel John, or whatever it is, lies under the feet again; and even Meredith’s cherry trees and yachts, graceful as they are, only open the windows into poetry. I doubt that it can be achieved by the writers who plan their books beforehand, it has to depend on a local impulse when the right interval is reached. But the effect can be exquisite, it can be obtained without mutilating the characters, and it lessens our need of an external form.
