Poe Passa ge Analysis
During the whole of a dull, dark, and soundless day in the autumn of the year, when the clouds hung oppressively low in the heavens, I had been passing alone, on horseback, through a singularly dreary tract of country, and at length found myself, as the shades of the evening drew on, within view of the melancholy House of Usher...I reined my horse to the precipitous brink of a black and lurid tarn that lay in unruffled luster by the dwelling...(with) vacant and eye-like windows.
Diction such as dark, soundless, singularly, and vacant all bring up the connotation that the person is very solitary. These help emphasizes the tone that the narrator is alone when he is doing this.
Details such as the clouds hung oppressively low in the heavens, dreary tract of country, the autumn of the year, and the shades if the evening drew on are all things that are not necessary to the story but help the reader feel what the character is feeling. These all help reinforce tone of being alone because they are all bleak and dreary which is pretty much being alone.
Imagery such as melancholy House of Usher, black and lurid tarn, and eye-like windows show that the reader is still sad but is being watched. These still show the connotation of being alone, but maybe he is being watched while he is alone.
