Sound as steering mechanism
Rhyme, near-rhyme, consonant collision, homophone and repeated mouth-shape can determine the next phrase before a prose argument has chosen it. Meaning is therefore not simply encoded first and voiced second; the act of voicing can discover the thought.
Effects
The method helps explain abrupt puns that become conceptual pivots, chains of semantic mutation and lines that hover between lyric and prose. It also clarifies why song lyrics can migrate naturally into essays and vice versa: both are being composed through a partially shared phonetic engine.
Late primary example
The Idea of a Cliche Expressing Itself Through Song lets rhyme and phonetic adjacency visibly steer the sequence: sound discovers the next semantic object before exposition has settled on one.
