The etymology of word ‘poetry’ (verb) comes from the Greek and it means ‘I create’.
The first written poetry, in the ancient world, had a religious subtext, used for prayers.
Initially, poetry was developed through storytelling; it helped to create an essential factor: correct rhythm, complex and reflective emotions as well as emphasizing the main meaning of the speech.
Poetry ,as a part of literature, has had many forms: hymn, formal – spoken form, tragedy, rhymes, elegies, lyric poetry or a new form – rap/slam poetry.
Rap, as a form of poetry started in late 20th century, this spread across most music genres and it is being continued.
A close relation to music – poetry could be sung and it’s called liturgical poetry – (psalms, hymns), mostly for inspirational purposes.
