11% of the top 100 operas are not about love. I got bored before I got to the end of this list, but I think I've proved my point. Which was that by far the most popular operas are about love.
Now let's examine our modern list.
Love with Happy Ending (4)The Postman Always Rings Twice --unwanted husband is murdered.
The Gospel of Mary Magdalene--he dies but then he comes back.
The ghosts of Versailles--I think the ending must be regarded as happy.
The Tempest--love is not the main story, but all ends happily.
Love (or at least sex) with Unhappy Ending (9)L'Amour de Loin--exactly what the title says, love from afar.
The Letter--she gets away with murder but kills herself anyway.
The Great Gatsby--Gatsby is murdered.
Adriana Mater--ambiguous ending.
A Streetcar Named Desire--she goes to the nut house.
Ainadamar--a great poet dies.
Sophie's Choice--woman chooses man who deserves her.
Not about Love (23)The Women in the Garden--literature.
Einstein on the Beach--not sure what it's about.
The Martyrdom of saint Magnus--religion.
Le Grand Macabre--politics.
The Red Line--politics.
The Village Singer--the love of singing.
Sweeney Todd--a profit making scheme.
King Harald's Saga--politics.
The Lighthouse--not sure what it's about.
Satyagraha--about Ghandi's political life.
Nixon in China--politics.
Licht: die sieben Tage der Woche--I lumped them all together, not sure what they're about.
The Death of Klinghoffer--old man in wheelchair is thrown off of ship.
Dead Man Walking--man is executed.
The man who mistook his wife for a hat--an opera about a medical condition.
Dolores Claiborne--child abuse and murder.
Heart of a Soldier--the 9/11 opera.
The Minotaur--a half human monster kills and eats people.
Moby Dick--madman gets everyone killed.
There are many more operas that could be listed, but I think I have cited enough. 66% of modern operas are not about love. The ratio of love to not love is now completely reversed. What love we have is often grotesque and perverted. Obviously these statistics are not scientific, and serve only to illustrate what is going on.
Jesus is given a sex life, but no one seems to realize that the others need this as well. Which of these operas that are not about love will survive? Sweeney Todd seems well on the way to immortality, but I don't hold out much hope for the rest. I loved most Ainadamar and L'amour de loin, both love plots.
For all I know the older operas were also 66% not about love and disappeared forever from our view. Why commission an opera that you know will disappear forever after it is presented? Why spend all that time writing an opera only to have it disappear forever? Maybe someone will come along that can answer this.
