In an opera, the beginning of an orchestral piece is called an overture. Other orchestral performances don't have a special name for the beginning.
An overture is a piece of music for the orchestra to play at the beginning of an opera or ballet. The word comes from the French word for opening because it opens the show. Overtures usually have tunes which are going to be heard during the opera or ballet. In this way it prepares the audience for what is to come. Many overtures in the 18th century were simply background music to get the audience's attention (people used to chatter during performances).
