Or, as here, rather supplementary queries, to NativLang on Rhymes

What's the reason and rhyme for rhymes?

I on Mnemotechnics:

Speaking of memory : how well do the chapters 2 to 6 in Genesis rhyme or how mnemotechnic are they, in Hebrew?

I mean, chapter 1 is from Moses getting a revelation on Sinai (unless chapter 1 was given to Adam and Jubilees to Moses, as some claim), but 2 - 6 would have been preserved by pre-Flood patriarchs, 7 - 11 by patriarchs living post-Flood, before Abraham had a whole caravan of servants who might preserve some papyrus (he could have got the first of that in Egypt) or similar.

I reckoned, learning them by heart is at least not impossible (if you think it is, tell that to Milman Perry or to both, he / they might need a laugh).

But are they very mnemotechnic or just short and syntactically simple enough?

II on Rhyme Schemes:

2:15 "within 3 seconds"?

Hmmm ... is this expectation fulfilled when hearing poems with rhyme schemes involving patterns like ABBA?
