written in a very regular form that matches its logical, argumentative thematic structure. Each stanza is ten lines long and metered in a relatively precise iambic pentameter.
The first two stanzas, offering advice to the sufferer, follow the same rhyme scheme, ABABCDECDE; the third, which explains the advice, varies the ending slightly, following a scheme of ABABCDEDCE, so that the rhymes of the eighth and ninth lines are reversed in order from the previous two stanzas.
"A partner in your sorrow's mysteries; For shade to shade will come too drowsily And drown the wakeful anguish of the soul"
reveals what will make the anguished soul drowsy. The sufferer should do everything he can to remain alert to the depths of his grief.
The word ‘mysteries’ is key here. The source of melancholy, as a sickness, is complex, and the medical science was only just developing at the time.
"shade to shade" - ghosts will come and make you drowsy - Keats is saying that you should hold on to your vulnerability and not give into drugs/alcohol
"That fosters the droop-headed flowers all And hides the green hill in an April shroud;"
‘Droop-headed flowers’ imitate the posture of humans when sad.
‘April shroud’ is apt, in that April is a rainy month, and a ‘shroud’ is not only the masking effect of the rain, but an echo of the references to death
contradiction - April is the month associated with Spring + growth.
Two sections: ABAB rhyme to CDE rhymes - change of mood.
"Then glut thy sorrow on a morning rose Or on the rainbow of the salt sand-wave Or on the wealth of globèd peonies;"
caesura after ‘shroud’, - stanza moves on.
the speaker urges the listener to ‘glut’ himself on as many sensual experiences as he can. All the senses are invoked, starting with a sweet-smelling rose, then a multi-coloured rainbow, shape and colour in the ‘globed peonies’, texture in the ‘salt-sand-wave’ and ‘soft hand’.
Three lines begin with ‘Or’, forming a refrain or anaphora, creating an effect of abundance of sensual experiences.
"Beauty that must die; And Joy, whose hand is ever at his lips Bidding adieu; and aching Pleasure nigh Turning to poison while the bee-mouth sips:"
The speaker explains these injunctions, saying that pleasure and pain are inextricably linked - melancholy’s companions are all defined by transience
Joy and melancholy are personified
'aching pleasure high' turns into poison
“negative capability” whereby he believed that there is always conflict between feelings and ideas and that the ambiguity of such conflict should be accepted.
"His soul shall taste the sadness of her might And be among her cloudy trophies hung"
Melancholy's trophies are 'cloudy' - temporary - links back to shroud
Keats could be suggesting the feeling of melancholy does not last forever, her hold comes and goes as it does with all emotions
