How did the frog introduce himself in poem and nightingale class10 cbse?

The frog in "The Poem and the Nightingale" by Vikram Seth, does not introduce himself, but rather presents himself as a more "realistic" alternative to the nightingale's romantic songs. Here's how he does so:

He starts by questioning the nightingale's romantic songs:

"Why do you sing such mournful songs,

Nightingale? Your voice is thin,

And all your notes are sad and long."

He then suggests a more practical approach:

"Sing of the things that really are,

The things that everyone can see:

The fields and flowers, near and far,

The sun and moon and sky and tree."

He finally suggests a song about himself:

"Sing of the frog, who sits all day

Beneath the lily-pad and sings,

And sings of his own simple way

Of life, and all the joy it brings."

The frog's approach is a critique of the nightingale's idealistic and unrealistic songs, showcasing the irony of the poem's theme - the clash between art and reality.
