There is no objection to the proposal: in order to learn to be a poet, I shall try to write a sonnet. But the thing you must try to write, when you do so, is a real sonnet, and not a practice sonnet.
My feeling is that poetry will wither on the vine if you don't regularly come back to the simplest fundamentals of the poem: rhythm, rhyme, simple subjects - love, death, war.
At somewhere around 10 syllables, the English poetic line is at its most relaxed and manageable.
In my opinion, it is easier to avoid iambic rhythms, when writing in syllabics, if you create a line or pattern of lines using odd numbers of syllables.
The basic rhymes in English are masculine, which is to say that the last syllable of the line is stressed: 'lane' rhymes with 'pain,' but it also rhymes with 'urbane' since the last syllable of 'urbane' is stressed. 'Lane' does not rhyme with 'methane.'
When we study Shakespeare on the page, for academic purposes, we may require all kinds of help. Generally, we read him in modern spelling and with modern punctuation, and with notes. But any poetry that is performed - from song lyric to tragic speech - must make its point, as it were, without reference back.
