Do you mean like what their class was, how they were seen in society?

It depends. Publicly working musicians in the early 18th century, including famous singers and composers, were basically considered "hired help" and did not have a high class status. They were lumped in with other people associated with the theater, like actors and actresses, who were not high class. For example they would be invited to work at parties in rich people's houses, but they would not be treated like guests, and sometimes had to eat separately from the rest of the guests with the household servants. This was common through about the early 19th century.

However, in the baroque period, chamber musicians working at courts were also common, and in that setting they enjoyed a higher status, especially women musicians, because then they weren't lumped in with actors/actresses. So basically, a private musician not expressly singing for their dinner was classier than someone who did, thems the breaks. Some musicians liked to sort of retire from the stage to court positions to raise their status, Farinelli did this pretty explicitly.

Would you like some reading on this? I only study singers but there is a very nice book that covers the social and economic side of singing for a living from 1600-1950, Singers of Italian Opera.
