When a rhythmic pattern of stresses recurs in a poem, it is called meter. Metrical patterns are determined by the type and number of feet in a line of verse; combining the name of a line length with the name of a foot concisely describes the meter of the line. Rising meter refers to metrical feet which move from unstressed to stressed sounds, such as the iambic foot and the anapestic foot. Falling meter refers to metrical feet which move from stressed to unstressed sounds, such as the trochaic foot and the dactylic foot. See also accent, foot, iambic pentameter, line.
