"Clown's Wife," by Johnson Agard, is written in free verse. This means that it doesn't have a set rhyme scheme or meter. There are a few rhyming lines within it. For example, lines 4 and 5 contain end rhyme in the words "throne" and "moan" and lines 7 and 12 contain end rhyme via the words "clothes" and "nose." The poem also ends with a rhyming couplet in "life" and "wife," but that is the most regular that the rhyme scheme ever gets. Similarly, there is no set meter. The syllable count shifts and expands as the poem progresses. After the first line of 7 syllables, line 2 drops to 4. The lines of stanza 2 each contain 8 syllables, and then the lines continue to expand until near the end of the poem, when they decrease in syllable count, but then end with a final, long line.
The tone, on the other hand, is something that can be more specifically discussed. The tone is very sympathetic to both characters, the clown and his wife. The clown himself is a very sad man, although it is never revealed why. At the same time he seems to take some level of solace in his wife's attempts to cheer him up and make him laugh. The wife is also a sad character, as she works hard to try to make him happy. Her efforts pay off to some extent, yet the nature of her narrative suggests that this is a pattern that repeats, day in and day out.
