1. Symbolism: The poem uses symbols to represent the death of a person. For example, the clock is a symbol of time, and stopping all the clocks represents the halting of time.
2. Metaphor: The poem uses metaphor to compare the death of a person to the setting of the sun and the fall of leaves from a tree.
3. Alliteration: The poem uses alliteration to create a sense of rhythm and musicality. For example, the repetition of the consonant "s" in the line "Stop all the clocks, cut off the telephone" creates a sibilant effect that mimics the sound of a clock ticking.
4. Assonance: The poem uses assonance to create a sense of harmony and unity. For example, the repetition of the vowel "o" in the line "And let us all be like him" creates a sense of smoothness and flow.
5. Imagery: The poem uses imagery to create a vivid picture of the death of a person. For example, the lines "The stars are not wanted now: put out every one; Pack up the moon and dismantle the sun" create a sense of darkness and desolation.
6. Rhetorical Questions: The poem uses rhetorical questions to emphasize the finality of death and the need to mourn. For example, the line "What shall we do for money? For love?" asks a question that has no answer, underscoring the helplessness and despair of the situation.
7. Repetition: The poem uses repetition to create a sense of urgency and to emphasize the importance of the moment. For example, the line "Stop all the clocks" is repeated twice, creating a sense of panic and urgency.
These techniques combine to create a powerful and moving poem that explores the themes of death, mourning, and the futility of human existence.
