Question

What mood does the setting of the raven create

Answer 1

It creates a haunting mysterious mood.

Answer 2

Melancholic perhaps.The narrator is sad because of the loss of his beloved one.He tries to concentrate in reading to forget his sorrows but he cannot.He is alone.Loneliness after such a loss surely indicates nostalgia and melancholy .there is a lamentation also so the mood is gloomy as usual in Poe.
