Sir Arthur Sullivan and Scott Joplin both shared the desire to write Grand Opera, while their publishers and the public preferred their more accessible popular music.
One of my students was so enamored of Joplin that he learned several of his complete original rags by the time he was 17.
Schubert fell into the same trap. He wanted to be the next Rossini. His talents, however, lay elsewhere. None of his many operas are in the repertory, and on the rare occasion when one of his operas is staged, ordinary people can’t get tickets because every music professor in the world is there first.
