What is the name normally given to two consecutive lines of poetry that rhyme?
Provided that the metre is the same, the lines are referred to as a 'couplet'.
A lyric poem is a poem that shows that one has passion towards a subject. For example, a poem that talks about music or a person and shows the poet's feelings towards it. Lyric poetry is usually a form of poetry with rhyming schemes that express personal feelings. It doesn't need to, but can be set to music. It will normally have a repeating stanza (set of lines) similar to a chorus.
