Final answer:
Meter is the term that describes the rhythmical pattern of a poem, determined by how syllables are stressed within the poem's lines.
Step-by-step explanation:
The heights and depths of how a person speaks when reciting a poem and something which affects its rhythm is called meter. Meter is the rhythmical pattern of a poem which is determined by stressed and unstressed syllables. Marking a poem's meter involves scanning the lines to identify these syllables.
Each unit of stressed and unstressed syllables is known as a foot. Different poems use different types of meter, such as iambic pentameter, to create certain effects.
Meter works interdependently with other poetic elements like rhyme and tone to influence the overall experience of the poem.
