Final answer:
William Blake's 'Songs of Innocence' and 'Songs of Experience' encompass a range of poetic techniques including imagery and symbolism, rhyme and meter, alliteration and assonance, and repetition and parallelism to enrich the textual experience and underline his themes.
Step-by-step explanation:
In Songs of Innocence (1789) and Songs of Experience (1794), William Blake used diverse poetic techniques to convey his thematic concerns. Some of these techniques include imagery and symbolism, rhyme and meter, alliteration and assonance, and repetition and parallelism. For instance, the intricate rhyme pattern in poems like 'The Lamb' and the various sound techniques in 'The Tyger' contribute to the overall impact of the poems. Blake's use of imagery often evokes vivid visuals that align with the themes of innocence and experience, while his adept use of sound in poetry through meter, rhyme, alliteration, and assonance helps create a rhythm that enhances the meaning. Poetic form and figurative language, including similes and metaphors, are also integral to how Blake's poems resonate with readers.
The question seems to be asking which of these techniques Blake employed in his works, and the answer is all of them. Through the use of sophisticated sounds and word choice, Blake orchestrates a harmonious blend that serves both aesthetic and thematic purposes. His use of structure of lines and stanzas together with meticulously chosen words allows the reader to appreciate the music in his poetry which often reflects on the human condition.
