Sentences saturated with similar sounds seem to stimulate synapses
Alliteration is the way English poetry used to be done. If you read Old English or Middle English poetry (even if you don’t understand it) you won’t find rhyming; you’ll find alliteration. If I recall correctly, rhyme didn’t come into English poetry until after the Norman Conquest.
I find alliteration to be rather hypnotic, and I’ve noticed Richard Bandler uses it sometimes in his presentations. (I’ve heard him use rhyme as well.) A recent bit of research, outlined at Cognitive Daily, indicates that it may stimulate memory as well:
Some scholars have suggested that alliteration makes a poem easier to remember: an important skill back in the days when books were so expensive that it might be cheaper to pay a bard to recite a poem than buy a written copy. But there has been little research about whether alliteration actually acts as a way to spur memory. More to the point, alliteration is rarely used throughout a poem: some of the words have to start with different letters. So alliteration might help you remember some of the poem, but it can’t help you remember the parts that aren’t alliterative. Or can it?
