In "In a Station of the Metro," Pound employs several elements of modernist poetry that enhance the setting of the poem. One of the key elements is the use of imagery, which is a hallmark of Imagist poetry. The imagery in the poem is precise and evocative, using the metaphor of "petals on a wet, black bough" to convey the appearance of the faces in the crowd.
Another element of modernism in the poem is the use of free verse, which allows for a more fluid and flexible structure than traditional rhymed verse. This helps to convey the sense of movement and energy in the crowded metro station.
Pound also employs a minimalist style, using only two lines to convey a powerful image and impression. This helps to create a sense of compression and intensity, which is fitting for the crowded and fast-paced setting of a metro station.
Overall, Pound's use of imagery, free verse, and minimalism in "In a Station of the Metro" effectively enhances the setting of the poem and captures the energy and movement of the crowded metro station.
