The title of this poem may suggest a metaphorical and vivid portrayal of a landscape in the beginning of spring.
The poem is about the coming of spring, whose sounds, colours and sights convey to the poet a feeling of tranquility and pleasure; this picture, anyway, has a tremendous shadow that is imminent: the human wreckedness which constantly ruins not only this peaceful environment, but also men theirselves. In fact, this antithesis between good and evil and between peace and war is absolutely evident, as going on with the analysis.
      There are several images that are used in order for the reader to get a full picture about the beauty of Nature that is awakening: Her sounds ("a thousand blended notes"), Her colourful flora ("primrose tufts in that green bower/the periwrinkle trailed his wreaths...the budding twings spread out their fan") and Her fauna ("the birds around me hopped and played").
      Anyhow, like previously stated, this calm and wonderful sight is ruined by the human thirst of evil, which is destroying every hope and vitality in the poet's heart (brings sad thoughts to the mind...what man has made of man?).
The poem is arranged into six quartains: the first one is characterized by some diphtoungs (thousand, notes, sate, mind), that may remind a particularly irregular armony. In almost every following stanza we have several dental and aspirate sounds (thousand, thoughts, through, faith, heart, think) that represent the constant sound of a delicate wind bringing life ("enjoys the air it breathes"). In addition to this, we have two key words (measure, pleasure): their "s" sounds catch the sweetness of the moment. The last stanza is enriched with "l" sounds, which can convey a sense of heartache and agony to the reader (belief, holy plan, lament), as well as "m" sounds that transmit a similar sense of death.
Last but not least, many other important words belong to the religious field: for instance, we have heart, soul, faith: these words testimony that the poet begins to ask the help of God or, possibly, he begins to doubt about His existence.

THE SOLITARY REAPER: ANALYSIS

      The title may suggest the poem is about a reaper who finds him/herself cultivating a crop on his/her own. Possibly, s/he's alone because of his/her free will (e.g. In order to avoid contacts with people that don't understand her) or because of his/her character, or even because of an hypothetical bad destiny.
      From a denotative point of view, the poem describes the melancholic movements of a reaper who's singing, as well as her appearent feelings and thoughts while she's working. At the very end of the poem, the reader realizes the entire picture is nothing more than a passed-by but still vivid remembrance.
     The poem is set up of four octaves: this division suggests to the reader the four seasons, or, more precisely, the passing by of time, that turns every image into a nostalgic and vague memory. The poem itself is full of natural elements (the Highland, the grain, the valley, the Cuckoo-bird, the hill). The reader in the first stanza may notice another important element: the use of the imperative mood, which can convey a sense of silence (behold, stop here, listen) and, nevertheless, a sense of deep greatness and isolation that can arise contemplating the Scottish lands; maybe, the poet directed these esortative words to himself, to keep the reaper's feeling of loneliness in his heart. The poet wants to describe the incredible variety of the sounds with the alternation of open and close vowel sounds, which all the stanzas are full of.
At the beginning of the second stanza, the reader notices that the verb chaunt is emphasized ("No nightingale did ever chaunt"), in order to highlight the extraordinary feature of that chant. In the same stanza there's also a contraposition between places ("Arabian sands... the farthest Hebrides"): this leads us to very different and distant places, the dry Arabian desert and the melty Hebrides, which we assume to have very different characteristics. The remoteness and melancholity of these images are also characterized by several adjectives (profound, weary, unhappy, far-off).
In the last stanza, a hyperbole is used, that highlights the beauty and melancholity of the moment, that the poet wants to make neverending ("as if her song could have no ending"..."long after it was heard no more").
