Final answer:
The phrases "blood-bedewed halls" and "corpse-like mask" contribute to a tone of horror in the narrative through their dark and death-related connotations.
Step-by-step explanation:
The tone created by the phrases "blood-bedewed halls" and "corpse-like mask" seems to evoke a tone of horror. These phrases suggest imagery typically associated with fear, death, and the macabre. When a story or poem includes phrases that refer to blood and macabre similes like a mask resembling a corpse, the author is typically engaging in tone-setting that is meant to incite a feeling of dread or revulsion. This is further intensified if set in a context that includes dark imagery, mentions of death, or settings that are historically tied to fear, such as a haunted house or a battlefield after a gruesome conflict.
The words and phrases an author chooses are essential in establishing the tone or feeling in the story. Words with strong connotations like "blood" and "corpse" carry with them a weight of cultural and emotional associations that contribute significantly to the horror atmosphere in a narrative. This effect can be compared to other tonal descriptors such as fearful, horrified, and forceful, which may also be evocative of a similar emotional response within the context of a story or poem.
