Likewise there is assonance in "slow" and "grow" and "midnight," "linnet," "glimmer" and "wings." These are examples of how Yeats creates the word music that makes this poem so excellent.

Note the way as well in which the last stanza suggests that the speaker feels a mystical connection with nature that endures even in spite of the intrusions of city life. He is always able to hear the "lake water lappping" on the shore of Innisfree, in spite of the "pavements grey" of his environment. This is something he hears in his "deep heart's core," and cannot be ignored or drowned out by the urban sounds that oppress him so.

One of the most significant aspects of this poem is the way that it uses powerful images to build up a picture of the healing, calming influence of nature on the soul. This is after all the importance of this island to the reader in the way that it represents a place that is completely separate to and different from his normal life in the city, defined by its "pavement grey" and generally by a lack of colour and tranquility. Note how the second stanza builds up an image of nature as being calming and soothing:

And I shall have some peace there, for peace comes dropping slow,
Dropping from the veils of the morning to where the cricket sings;
There midnight's all a glimmer, and noon a purple glow,
And evening full of the linnet's wings.

The island is defined by the nature that encompasses it, with evening described as being "full of the linnet's wings" and peace is imagined as "dropping from the veils of the morning," because it is so tangible the speaker imagines that he can see it and reach out and touch it. Note too the alliteration in "glimmer" and "glow" which help to create the songlike feel of the poem and the attractive site that the poet is describing. The poem also makes use of assonance to reinforce its strong rhythmic qualities. The speaker can almost be imagined to chant this poem to himself as he goes about his business in the city, and he uses the powerful images in this poem to sustain him and strengthen him in the face of the "pavements grey" and the oppressive toil of materialistic society.

One of the key elements of this poem is the way that it presents us with an impossibly idyllic dreams of a person who is clearly stifled and in danger of being suffocated by the urban sprawl in which he lived. We can see in Innisfree a symbol of the kind of relationship with nature and example of natural beauty that so many industrial-era Victorians longed for. Note the way that the speaker's dream is presented as being characterised by peace and the transcendent beauty of the island. The speaker desires a simple, solitary, peaceful and pastoral life on the island, in his small cabin and with a description of his bean rows and a "hive for the honey bee." The description of peace coming "dropping slow" as if it were honey falling from a spoon, combines with examples of imagery such as "There midnight's all a glimmer" to create a lyrical landscape that is almost dream-like in its beauty. This lyric therefore celebrates the union with nature that man can have which is necessary for his existence.
