There are several words that could answer this question adequately. In Edgar Allen Poe's poem, "The Bells," there are many allusions to mood and tone. In the fourth stanza in particular, "melancholy," "solemn," "affright," "alone," "monotone," "sobbing," "moaning," and "groaning" are all words that contribute to an overall feeling of gloom and despair. I hope this helps.
