Final answer:
The discussion involves analyzing poetic devices such as line structure, rhyme scheme, and rhythm in poems by Yeats, Keats, Hardy, and Cohen, and how these devices shape the poems' effects and meanings.
Step-by-step explanation:
The question concerns the analysis of poetic devices and structures in specific poems, focusing on how these elements contribute to the meaning and effect of the poems. When examining Yeats' stanza, it is essential to pay attention to the line structure and the internal rhyme of 'feather' with 'heather,' which emphasizes the harmony of the moment being described. The stanza from Keats's 'Eve of St Agnes' showcases a complex and sophisticated rhyme scheme, while Thomas Hardy's 'Neutral Tones' is notable for its word choice. Similarly, attention is drawn to how the rhyme scheme in Yeats's edited version of Pater contributes to rhythmic patterns, and how Cohen's 'Anthem' uses a literary technique known as refrains, to control the mood.
