A chamber orchestra has the same instruments as a full orchestra, just reduced in numbers. There would be two to four cellos in most chamber orchestras.
The three types of orchestra are symphony, chamber, and string. The symphony orchestra consists of woodwinds, brass, strings, and percussion. The chamber orchestra usually has less than 50 musicians. A string orchestra only has string instruments - violin, viola, cello, and upright bass, piano, and harp.
The main purpouse of the cello is to support violins with bass sounds or a secodary melody. The cello was given more of a secondary role in orchestral playing until Antonio Dvorak gave the cello a important role in orchestra. Early cellists were not able to show the expressive qualities that modern day cellists are able to convey. Part of the reason for this is that the cello strings were made out of gut instead of steel.
