The meter of “On the Move” is largely iambic pentameter: the most common meter in English poetry. An iamb is a poetic foot in which an unstressed syllable is followed by a stressed syllable. A pentameter consists of five poetic feet. Line 20 is a strong example of an iambic pentameter: “They scare a flight of birds across the field.” Sometimes there is an extra, unstressed syllable at the end of the line. This is known as a feminine ending, as in the following two lines: “The blue jay scuffling in the bushes follows” (Line 1), and “That spurts across the field, the wheeling swallows” (Line 3).
