Answer:
The extent of Poe's use of dark or sad tones can be found in his work although it varies widely from piece to piece. Poe's tone is overwrought, dark, frantic and intense throughout this whole short story. The tone of 'Alone' is sombre. Phonetically, you can see this exhibited in words like alone, thunder, or demon. Words with vowels that are lower on the tonal scale such as long “a” or “o” are in the category of phonetically darkened tones.
