Final answer:
The quadruple meter in music has a repeating pattern of stressed and unstressed beats with the first beat emphasized the most, resembling two duple patterns combined. Meter in poetry similarly uses stressed and unstressed syllables to create rhythm. Deviations from strict metrical patterns in poetry are often used for artistic effect.
Step-by-step explanation:
The quadruple meter in music is represented by the pattern [ > U > U][ > U > U ], indicating a repeated sequence where the first and third beats are stressed, with the first beat receiving the strongest emphasis. This creates a rhythmical structure composed of two duple patterns, where the quadruple meter has a total of four beats per measure. The notation > signifies a stressed beat and U signifies an unstressed beat.
Meter in poetry, similar to meter in music, involves the regular pattern of stressed (/) and unstressed (x) syllables. For example, the iambic meter is noted as x /, with the stress falling on the second syllable. Another common meter, the tetrameter, can be seen in various forms such as the iambic tetrameter, where there are four iambs per line.
It is important to understand that the regularity of the meter provides a rhythmical framework which poets can choose to strictly follow or deviate from for artistic effect. Shakespeare, for instance, sometimes added an extra beat to create a unique rhythm or place emphasis on certain words.
