So Swann was not mistaken in believing that the phrase of the sonata did, really, exist. Human as it was from this point of view, it belonged, none the less, to an order of supernatural creatures whom we have never seen, but whom, in spite of that, we recognise and acclaim with rapture when some explorer of the unseen contrives to coax one forth, to bring it down from that divine world to which he has access to shine for a brief moment in the firmament of ours. This was what Vinteuil had done for the little phrase. Swann felt that the composer had been content (with the musical instruments at his disposal) to draw aside its veil, to make it visible, following and respecting its outlines with a hand so loving, so prudent, so delicate and so sure, that the sound altered at every moment, blunting itself to indicate a shadow, springing back into life when it must follow the curve of some more bold projection. And one proof that Swann was not mistaken when he believed in the real existence of this phrase, was that anyone with an ear at all delicate for music would at once have detected the imposture had Vinteuil, endowed with less power to see and to render its forms, sought to dissemble (by adding a line, here and there, of his own invention) the dimness of his vision or the feebleness of his hand.
