When the familiar is suddenly strange
Or the well known is what we yet have to learn,
And two worlds meet, and intersect, and change;

By whom, and by what means, was this designed?
The whispered incantation which allows
Free passage to the phantoms of the mind?

By you; by those deceptive cadences
Wherewith the common measure is refined;
By conscious art practised with natural ease;

By the delicate, invisible web you wove –
The inexplicable mystery of sound.

From T.S. Eliot, To Walter de la Mare
