Final answer:
Early in Part Two, the mood around Camelot changes as the Lady of Shalott becomes discontent with her life of mere shadows, leading to a darker atmosphere that contrasts with the earlier joyful depiction of Camelot.
Step-by-step explanation:
The mood of Camelot experiences a significant shift as depicted early in Part Two of Tennyson's poem, where the initial jubilant and idyllic atmosphere begins to darken. This change is symbolized by the growing obsession of the Lady of Shalott with the outside world as seen through her mirror. While Camelot continues to thrive with the daily occurrences of knights riding, and people going about their happiness, there's an underlying tone of sadness and longing from the Lady's perspective as she becomes increasingly discontent with her life of shadows and reflections.
The transformation is further emphasized with imagery of a funeral procession heading to Camelot, contrasting the earlier images of damsels, shepherds, and pages. The line "I am half sick of shadows," said by the Lady, underscores her growing despair and foreshadows her tragic fate. This line is a critical turning point in the poem, marking the moment when the Lady decides to break free from the confines of her situation, leading to a darker mood as she faces the consequences of her actions.
