1. Musical Instruments of the Orchestra in the Western Tradition

2. What is an Orchestra ?
Orchestra is an old Greek word which means ‘a dancing place’.
In Greece, during the 5th century B.C., orchestra was the name given to the space in front of the main acting area which was used by the chorus, who danced as well as sang, and by the instrumentalists of open air theatres.
Today we use the word orchestra to mean a reasonably large collection of instruments playing together as a group.
