Professor Cornelia C. Contralto II

Cornelia playing the "Call of Cornelia" on an organ

Professor Cornelia C. Contralto II, voiced by Carol Channing, is the curator and owner of the town's sound museum. She, like her great-grandmother Professor Cornelia C. Contralto I, is an expert in acoustics and vibration. She also helps Carlos develop his instrument and find the perfect sound. She is always looking to add to her great-grandmother's sound collection, and at the end, she annexs Carlos' new and improved instrument. She was also responsible for playing what he called the "Call of Cornelia" on her organ.
