What Type of Poem Is "Blow, Blow Thou Winter Wind" by Shakespeare?

"Blow, Blow Thou Winter Wind" by William Shakespeare is a lyrical poem found in his play "As You Like It." Lyrical poems are those that have musical qualities. The character to whom the lines belong, Amiens, sings the poem.

In the play, Amiens was supposed to entertain Duke Senior, whose brother has taken his throne, but he instead sings this song about faithless friends. In it, he personifies the winter wind, comparing it to an ungrateful and rude friend. The repeating four lines that follow each stanza have contrasting messages in them. On the one hand, Shakespeare writes the disturbing line "Most friendship is feigning, most loving mere folly." Two lines later he writes, "This life is most jolly."
