Poems In Yoruba

If I wanted to write a poem in Yoruba how could I do that best? Let's say I wanted to use rhyme, Yoruba rhymes are only a few (if I don't take into account tones): a, e, e, i, o, o, u, an, on, un. Well, if you say it only rhymes when we got same pitch than it becomes a bit more challenging. And do I chose my words so that the tone of the whole poem form kind of a melody? 

Could maybe somebody write a poem in Yoruba and explain how s/he has done it? Thanks! 

Ulli Beier writes about Yoruba poetry that it does not have metre since there is “no important difference in the length of vowels nor a marked difference in between stressed and unstressed syllables”. He directs us to the second Odu Journal in which E. L. Lasebikan argues that tone imposes a pattern on Yoruba poetry, e.g. alternating lines ending on the same tone. However, there are only few cases in which such a regular pattern is present. Common techniques used in Yoruba poetry are: metaphors, similes, onomatopoeia, repetition, alliteration, humour, irony, pathos and bathos (but not rhyme). It can be played on the drum using the three tones of the language: low (do), mid (re) and high (mi). It is more intelligible to a native speaker than utterances pronounced with a wrong pitch pattern.
