Lyrical poetry allows an author to express their feelings and emotions through a character. What makes lyrical poetry particular in literature is the structure in which the poem is written; it is written as the lyrics for a song, and it contains elements of melody and metric patterns.
A lyric poem provides the poet with space to express his personal feelings he cannot show otherwise in prose or any other form. They are free to address anything and write in a way that it could be sung. It also provides the poet an opportunity to show how he can turn words into emotional outbursts that could be turned into music.
The poet can freely compose, repeat and use rhyming patterns for music.
