Answer: I believe it is refrain and Alliteration
Explanation: Refrain means that the end of the Stanza ends with the same line " From the Bells, bells, bells, Bells, Bells, Bells, Bells--
From the jingling and tingling of the bells "
This repeats throughout the whole poem.
Alliteration means I repeats or rimes- " Silver bells " And " foretells " And so on
I hope this helped!
