We may write reams and reams of poetry, but when we attempt to formalize the structure of our poems, in our bid to share them with poetry aficionados, we must pay deference to the rules that would birth the formal structure of our choice. The rules may pertain to the number of lines, as in four lines make a quartet, the rhyme scheme, the number of syllables that each line can have, the meter and so on and so forth.
There are online tools available to help you to count syllables for each line of your poem. https://www.howmanysyllables.com/syllable_counter/ – Use this site if you are writing a haiku or a form of poetry that follows a ‘code of conduct’ for the number of syllables allowed in each line to remain true to the form of poetry that you are composing.
