The entire concept of making a living off recordings/reproductions didn't really start until the invention of the printing press which allowed for mass reproductions.

Prior to that anyone with enough time on their hands and skills could legally reproduce any text, music, painting, etc for profit. Artist where largely compensated for performances or for original artwork. There was more relative demand for live performances because of the lack of other available entertainment options.

Now the primary issue with being a successful artist is the attention economy is incredibly competitive, and the barriers to entry are incredibly low.
