Alliteration vs Assonance== 
 I added that alliteration requires that the sound be a consonant one.  I'd done this in the past, but it was removed without explanation.  Note that alliteration does require the repetitve be a consonant according to every source I can find.  If the repetitve sound or letter is a vowel, then it is assonance.  It's a common enough misunderstanding, but an easy one to verify.
