Gaston Leroux 
Phantom of the Opera 

During Christine’s childhood, which is described retrospectively in the early chapters of the book, her father tells her many stories featuring an 'Angel of Music’, who, like a muse, is the personification of musical inspiration. On his deathbed, Christine’s father tells her that from Heaven, he will send the Angel of Music to her. Christine is eventually given a position in the chorus at the Paris Opera House.
