what do roderick's artistic efforts-his guitar solo, his painting, and his poem "the haunted palace"-reveal about his state of mind?

The place is just really creepy. Roderick fits into this setting because all of his artistic pursuits are as bizarre and creepy as the house. His guitar solo isn't calming or the stuff of campfire music; it is morose and strange. His poetry mirrors the very house they are in. Roderick’s disturbed state of mind reflects the very disturbing state of the House of Usher.
