His thinking of the human condition intensifies the poet’s desire to escape the world.
‘Fade’ used in last line of stanza II and the first line of stanza III– ties them together… ‘Fade’ and ‘dissolve’- he wants to escape (possibly to get away from the illness of TB that Keats developed in real life) Away! for I will fly to thee, Not charioted by Bacchus and his pards, But on the viewless wings of Poesy, Though the dull brain perplexes and retards: Already with thee!
Hearing the song of the nightingale, the speaker longs to flee the human world and join the bird.
His first thought is to reach the bird's state through alcohol--in the second stanza, he longs for a "draught of vintage" to transport him out of himself.
"Nightingale" also differs from the other odes in that its rhyme scheme is the same in every stanza (every other ode varies the order of rhyme in the final three or four lines except "To Psyche," which has the loosest structure of all the odes).
Each stanza in "Nightingale" is rhymed ABABCDECDE, Keats's most basic scheme throughout the odes.
But after his meditation in the third stanza on the transience of life, he rejects the idea of being "charioted by Bacchus and his pards" (Bacchus was the Roman god of wine and was supposed to have been carried by a chariot pulled by leopards) and chooses instead to embrace, for the first time since he refused to follow the figures in "Indolence," "the viewless wings of Poesy." The rapture of poetic inspiration matches the endless creative rapture of the nightingale's music and lets the speaker, in stanzas five through seven, imagine himself with the bird in the darkened forest.
In the fifth stanza, the speaker says that he cannot see the flowers in the glade, but can guess them "in embalmed darkness": white hawthorne, eglantine, violets, and the musk-rose, "the murmurous haunt of flies on summer eves." In the sixth stanza, the speaker listens in the dark to the nightingale, saying that he has often been "half in love" with the idea of dying and called Death soft names in many rhymes.
tender is the night, And haply the Queen-Moon is on her throne, Cluster’d around by all her starry Fays; But here there is no light, Save what from heaven is with the breezes blown Through verdurous glooms and winding mossy ways. In line 3 he announces he will use the ‘viewless wings of Poesy’ to join the nightingale’s world.
In choosing poesy, he is calling on poetry and Imagination… the whole stanza is full of senses which heightens the whole experience.
Themes With "Ode to a Nightingale," Keats's speaker begins his fullest and deepest exploration of the themes of creative expression and the mortality of human life.
In this ode, the transience of life and the tragedy of old age ("where palsy shakes a few, sad, last grey hairs, / Where youth grows pale, and spectre-thin, and dies") is set against the eternal renewal of the nightingale's fluid music ("Thou wast not born for death, immortal bird! The speaker reprises the "drowsy numbness" he experienced in "Ode on Indolence," but where in "Indolence" that numbness was a sign of disconnection from experience, in "Nightingale" it is a sign of too full a connection: "being too happy in thine happiness," as the speaker tells the nightingale.
I cannot see what flowers are at my feet, Nor what soft incense hangs upon the boughs, But, in embalmed darkness, guess each sweet Wherewith the seasonable month endows The grass, the thicket, and the fruit-tree wild; White hawthorn, and the pastoral eglantine; Fast fading violets cover’d up in leaves; And mid-May’s eldest child, The coming musk-rose, full of dewy wine, The murmurous haunt of flies on summer eves.
