have some sadness in them He says Our sweetest songs are those that tell of saddest thought Humans often mix happiness with sadness Hence Shelley requests the skylark to teach humans to feel the same pure joy as the bird Half the Gladness At the end of the poem Shelley directly asks the skylark for help He says Teach me half the gladness That thy brain must know In simple words Shelley asks the beautiful bird to teach him a little bit of happiness the bird feels He wants to learn how to sing or write poetry as wonderfully as the skylark If he could share even half of the bird s joy he believes his words would inspire the world People would listen to him just like he is listening to the skylark s magical song To sum up Shelley admires the skylark s ability to stay joyful He wants to learn the bird s secret of happiness so that he can experience joy and share it with the world through poetry
