In "Musician's Daughter," what is the difference if "grand" is replaced with "large" in the description of the room?

When "grand" is replaced with "large" in the description of the room, the sense of magnificence is indeed lost. The term "grand" conveys not just size but also an aura of splendor, majesty, and sophistication, evoking an emotional response associated with grandeur and beauty. In contrast, "large" simply conveys the physical size of the room without any additional connotations related to elegance or splendor. Therefore, the replacement alters the perception of the room from one that suggests beauty and impressiveness to one that merely describes it as big, thereby diminishing the overall impact of the description.
