Final answer:
A poet does not create musical language in free verse by following a strict rhyme scheme; instead, assonance, alliteration, repetition, and parallel structure are used to establish rhythm and coherence.
Step-by-step explanation:
The aspect of poetry that is NOT a way a poet creates musical language in free verse is by following a strict rhyme scheme. Free verse poetry often utilizes literary devices such as assonance and alliteration, as well as repetition and parallel structure to create a rhythm or musicality. However, it is characterized by its lack of consistent metrical patterns and rhyme schemes, which are more typical of traditional forms of poetry. This freedom allows the poet to focus on thematic, syntactic, or semantic repetition and development to create coherence in the poem.
