Etymology

from Latin orchestra "the place in front of the stage where prominent persons sit," from Greek orchēstra "a semicircular area in front of the stage of a theater where the chorus dances," from orcheisthai "to dance"

Word Origin

In front of the ancient Greek stage was a semicircular space where a chorus danced, sang, and commented on the action of the play. The Greek word orchēstra referred to this space. It came from the verb orcheisthai, meaning "to dance." The word was borrowed into Latin, but the Roman orchestra was reserved for the seats of prominent persons, such as senators, instead of for a chorus. When English borrowed the word, it indicated the space occupied by a group of musicians, usually right in front of the stage. It also was used to refer to the group of musicians itself. Later, orchestra came to mean the forward part or all of the main floor of a theater.
