1. All the world's a stage. (repetition of the "A" sound)
2. And one man in his time plays many parts. (repetition of the "A" sound)
3. Then a lover, sighing like furnace, with a woeful ballad made to his mistress' eyebrow. (repetition of the "I" and "U" sounds)
4. Then a soldier, full of strange oaths, and bearded like the pard, jealous in honour, sudden and quick in quarrel, seeking the bubble reputation even in the cannon's mouth. (repetition of the "U" and "E" sounds)
5. And his big manly voice, turning again toward childish treble, pipes and whistles in his sound. (repetition of the "I" sound)
6. Last scene of all, that ends this strange eventful history, is second childishness and mere oblivion, sans teeth, sans eyes, sans taste, sans everything. (repetition of the "A" and "E" sounds)
These instances of assonance create a sense of musicality and add depth to the language, enhancing the overall poetic experience of the poem.
