The alliteration effect on a reader is all about setting mood and creating atmosphere. If you spoke with alliteration in everyday conversation, then I’m sure people would find it confusing/annoying…but reading is different. Try reading some classic examples of alliteration and focus not so much on the exact words, but how they make you feel. For instance, read ‘Jabberwocky’ by Lewis Carroll and focus on the raucous, discordant feeling that is created with the use of alliteration (a tone that matches the poem down to a tee). Another of my favourites is ‘The Raven’ by Edgar Allen Poe, “Once upon a midnight dreary, while I pondered weak and weary…” the sonorous sounds used within this poem create a deliciously unnerving atmosphere for the reader.
