There are several reasons why Shakespeare may have chosen to write in iambic pentameter.
1. Tradition: Iambic pentameter had a long tradition in English poetry and drama, dating back to the 14th century. It was the dominant meter of the time and was considered the most suitable for serious and elevated subjects such as tragedy and history. Shakespeare's use of iambic pentameter was in keeping with the prevailing literary conventions of his era.
2. Rhythm and Fluidity: Iambic pentameter creates a natural rhythm and flow of language that mimics the cadences of human speech. The regular beat and alternating stressed and unstressed syllables provide a pleasing auditory experience and make the verse easy to recite and remember. Shakespeare's skillful use of iambic pentameter contributes to the musicality and poetic quality of his plays.
3. Dramatic Expression: Iambic pentameter allows for greater flexibility and variation in language compared to prose. The meter and rhythm provide a framework within which Shakespeare could explore a wide range of emotions, from deep sorrow and anguish to humor and wit. The meter can serve as a tool to convey the emotional state and inner thoughts of characters, adding depth and nuance to their dialogue.
4. Character Differentiation: Iambic pentameter can be used to differentiate between different characters and social classes in a play. For instance, Shakespeare often used regular and consistent iambic pentameter for noble characters, while lower-class characters or fools might speak in more irregular or prose-like language. This use of meter helps to establish and distinguish the various social hierarchies and relationships within the plays.
5. Versatility: Iambic pentameter offers a versatile medium for Shakespeare to express different poetic styles and effects. He could use it to create humorous doggerel, eloquent speeches, passionate soliloquies, and lyrical passages. The meter allowed Shakespeare to explore a wide range of poetic techniques, imagery, and rhetorical devices.
In conclusion, Shakespeare's choice to write in iambic pentameter is a testament to his mastery of language and poetic form. It was a meter that was familiar to his audience and served to enhance the dramatic expression, emotional depth, and poetic beauty of his plays.
