Laugh and be merry remember better the world with a song better the world with a blow and teeth of a wrong laugh for the time is brave a thread the length of a spawn laugh and be proud to be along to the old proud pagan of man what is the rhythm pattern in this stanza

When trying to determine the rhyme pattern in a poem or just a part of it, you only have to look at the final words in each line - based on which words rhyme, you will know what the rhyme pattern is.
In this stanza, we have the following pattern: AABB. This means that song (the last word in the first line) rhymes with wrong (the last word in the second line) which is why they are both A. B refers to the words span and man (the last words in lines 3 and 4) which also rhyme.
