Metrical+Feet

Meter is often used to put emphasis on certain words or syllables that the poet wants to draw the reader's attention to. A combination of meters can produce a similar effect by drawing attention to the line that has a different pattern.
 * Meter** in poetry is a measure, in **feet**, of the rhythmic pattern or accents in a verse. One foot consists of stressed and unstressed syllables, and a meter is the sequence of these groups of syllables. The number of feet in a line determines the name of the meter, i.e. (1) monometer; (2) dimeter; (3) trimeter; (4) tetrameter; (5) pentameter; (6) hexameter; (7) heptameter; (8) octameter

e.g. The first line of Larkin's "Love Songs In Age" is written in iambic pentameter: "She kept her songs, they kept so little space". The unstressed-stressed pattern of the first verse sets a natural rhythm for the reader, as shorter and less significant words like "She" and "her" receive less stress and more important terms such as "kept" and "space" are highlighted.
 * -Iamb:** each foot consists of one unstressed syllable followed by a stressed on
 * **U /** || **U /** || **U /** ||

e.g. Larkin's "Reference Back" is primarily trochaic, for instance the first verse of the last stanza: "Truly, though our element is time," The last syllable is dropped so that the stressed syllable is at the end of the verse, which emphasizes the importance of "time" in the poem.
 * -Trochee:** each foot consists of one stressed syllable followed by an unstressed one
 * **/ U** || **/ U** || **/ U** ||
