Read the poem.

I Wandered Lonely as a Cloud

by William Wordsworth

I wandered lonely as a cloud

That floats on high o’er vales and hills,

When all at once I saw a crowd,

A host, of golden daffodils;

Beside the lake, beneath the trees,

Fluttering and dancing in the breeze.



Continuous as the stars that shine

And twinkle on the Milky Way,

They stretched in never-ending line

Along the margin of a bay:

Ten thousand saw I at a glance,

Tossing their heads in sprightly dance.



The waves beside them danced; but they

Out-did the sparkling waves in glee:

A poet could not but be gay,

In such a jocund company:

I gazed—and gazed—but little thought

What wealth the show to me had brought:



For oft, when on my couch I lie

In vacant or in pensive mood,

They flash upon that inward eye

Which is the bliss of solitude;

And then my heart with pleasure fills,

And dances with the daffodils.
How does the speaker’s stating that his “heart with pleasure fills, / And dances with the daffodils” affect the tone of the poem?

It works to lessen the poem's mournful tone.
