What is Wordsworth's tone in "I wandered lonely as a cloud"?

However difficult the term “tone” can be, we can begin at the last stanza, where Wordsworth tells us he remembers the incident:

“In vacant or in pensive mood,

They flash upon that inward eye”

As we read his description of the daffodils, we understand that he is not simply describing the moment, but giving the reader a vision of the mood, the feeling of the host of daffodils, together with the clouds, and most importantly, the waves. The emotions this natural event gave the poet are reflected in his choice of such words as “sprightly,” “spree,” “jocund,” and “bliss.” The tone of the poem also comes from the Romantic sense that our individuality, while valuable, is part of a “host” of Nature, by the myriads of stars, of the “never-ending line” of flowers, of multitude. (In “Preface to Lyrical Ballads” Wordsworth describes poetry as “a moment of passionate intensity, recollected in tranquility.”) So, one can say the “tone” of the poem is pensive contentment of a fondly and passionately remembered moment in his life.
