@Imadethisupwithnoforethought – I also like thinking about this subject.
I have considered artists. Heck, I know some personally, artists that release recordings and perform at a professional level. I think what people envision is an artist who just loves to sing (or act or whatever) so much, that they would do it all day for free if they could. But in reality, no one can do what they love all day for free, unless they are independently wealthy. The artist needs an income, and that generally comes from their performance, if they perform at a professional level (which is a lot of work). Otherwise, they work a “real job” and sing at an amateur level. Not paying artists, and forcing them to work at something they do not love (in order to pay the bills) not only hurts the artist, but it marks a decline in the quality of art that is available to us, because only people who are amateurs can really afford to perform anymore.
Consider also, the stuff that goes into a performance. It’s not just the hour they’re onstage. It’s the voice lessons, the performance outfits, the gas to and from the stage or studio, the studio or hall rental, all the stage hands, engineers, producers, people who work at the disc factory, people who type in the data in the liner notes, the makeup artists and the key grip, the guy with the camera, the microphone technician, and a thousand other people who earn their living by making the product for you to enjoy. It’s not just the artist.
If you wrote a song that was popular 200 years ago, you may well be concerned about controlling the reproduction. Mozart, for example, frequently rearranged his own works so that he could be the publisher of those arrangements (and get the financial benefit from that by being first to do so). Haydn had an issue where rivals at court stole some of his compositions and published them for very little money, depriving him of income from being able to publish them himself. So, I would say that old-time composers were very concerned about the revenue that came in from their works, even if it was scores and sheet music, not actual recordings.
While the writers of the Bible may not have written with the expectation of financial reward, I bet surely that the bards performing as Homer were in it for a few coins or a meal or a safe place to sleep for the night. The Bible writers were moved by faith. When I work at my job, I am moved not by faith, but by the prospect of paying for my mortgage and dinner, more like “Homer.” And my friend the mezzo-soprano loves singing, but she sings professionally and releases recordings because she would like to pay her mortgage and eat dinner, too. Do you do your job for fun?
