(Soprano, Low G to High A) Daughter to Mrs. Paroo and sister to Winthrop, she is the stuffy, conceited librarian and piano teacher in town. She is very learned and defends the “questionable” books that are in the library. She was close to her deceased father’s friend, Mr. Madison, and the town believes that she had an affair with him. After all, he left the library to the town, but all the books to her! There was no affair, and he was like an uncle to her. At first, after meeting Harold Hill, she dislikes him but then gets to know him better, and we see a transformation in her while she falls in love. She comes to realize that he really does want to make a difference, and changes things in the town. They end up together. Sings: “Piano Lesson,” “Goodnight My Someone,” “My White Knight,” “Shipoopi,”(Dance only) “Will I Ever Tell You,” “Till There Was You,” & “Seventy-six Trombones” reprise.
