Question

What is the rhyme scheme used in the poem fatherwillliam?

Answer 1

It is ABAB

The last word of every alternate line rhymes:

"You are old, Father William," the young man said,

"And your hair has become very white;

And yet you incessantly stand on your head—

Do you think, at your age, it is right?"

"Said" rhymes with "Head" - A

"White" rhymes with "Right" - B

Hence, ABAB
