Balaustion's Adventure

And who hears music, feels his solitude
Peopled at once — for how count heart-beats plain
Unless a company, with hearts which beat,
Come close to the musician, seen or no?
And who receives true verse at eye or ear,
Takes in (with verse) time, place, and person too,
So, links each sense on to its sister-sense,
Grace-like: and what if but one sense of three  
Front you at once? The sidelong pair conceive
Thro' faintest touch of finest finger-tips, —
Hear, see and feel, in faith's simplicity,
Alike, what one was sole recipient of:
Who hears the poem, therefore, sees the play.

                                 Robert Browning (1871)
