Somewhere or other there must surely be
 The face not seen, the voice not heard,
The heart that not yet--never yet--ah me!
Made answer to my word.
Somewhere or other, may be near or far;
Past land and sea, clean out of sight;
Beyond the wandering moon, beyond the star
 That tracks her night by night.
Somewhere or other, may be far or near;
 With just a wall, a hedge, between;
With just the last leaves of the dying year
 Fallen on a turf grown green.
The opening line of each stanza is repeated with slight variations, a device known as  anaphora . This emphasises the message of the poem; the speaker’s yearning for love. Note that the second and third stanzas are almost identical apart from the reversal of ‘near or far’ to ‘far or near’. 
 If spoken aloud this line has a rhythmic sonority that draws the reader in.
