How many instruments does a string section has?

A typical string section in an orchestra consists of four main types of instruments: violins, violas, cellos, and double basses. The first and second violins are usually the largest groups, followed by violas, cellos, and fewer double basses. The exact number of each instrument can vary depending on the specific orchestral arrangement. Overall, the string section can include anywhere from 20 to over 50 musicians.
