Step-by-step explanation:
The lyric type of poetry reveals the speaker's thoughts and emotions using a regular rhyme scheme and meter. The poem "The Lamb", by William Blake, is an example of such type of poetry. We can observe those characteristics:
Little Lamb who made thee

By the stream & o'er the mead;
Gave thee clothing of delight,
Softest clothing wooly bright;
Gave thee such a tender voice,
Making all the vales rejoice!
Little Lamb who made thee
Dost thou know who made thee [...]
A sonnet consists of 14 lines, but the structure and rhyme scheme may vary according to the kind - Shakespearean or Italian.
A free verse has no regular rhythm and the lines do not rhyme.
Pastoral does not refer to the structure of the poem, but to its theme. A pastoral poem idealizes rural life and landscapes.
