What is the Number of players in classical music?

This question is a little too general, but I think I know the answers you are looking for.
Early orchestras had 30 to 60 players. As the music progressed to the classic/romantic period, the size of a symphony ochestra increased to 60 and above, exceeding 100 or hundreds, if choirs were involved.

Then there are the groups with fixed numbers, like quartets and trios that tell you from the designation how many players are needed. Another grouping popular in the past was the chamber orchestra. This was just a small orchestra. This is not to be confused with groups that played "chamber music". They played pieces specifically written for three to nine performers. This was the amount of musicians that could fit in a large room or "chamber" in a rich person's house and still have room for spectators.
