An acoustic marker is a deliberate sonic device—such as alliteration, assonance, consonance, onomatopoeia, or rhythmic repetition—that functions as an auditory signal within a poem to highlight thematic shifts, emotional intensity, or structural transitions. These markers operate beneath the semantic layer, guiding the listener’s ear and reinforcing meaning through sound patterns; for instance, the repeated “s” sounds in “softly, silently, slipping” create a hushed atmosphere that mirrors secrecy or stealth, while sharp plosives like “k” or “t” can convey tension or abruptness. Poetry students should recognize acoustic markers as essential tools for enhancing musicality, mood, and subtext without relying solely on imagery or narrative.

These markers function like auditory signposts, guiding the listener’s attention or reinforcing meaning through sound. For example, sibilance may denote secrecy, while plosives can convey tension. Poetry students should practice identifying and deploying acoustic markers to enhance musicality and subtext without overwhelming semantic clarity.
