Have you ever attended a concert?
Or have you ever watched an orchestra on television?
All of the musical instruments come together in an orchestra.
String, percussion, woodwind, brass, and keyboard instruments make up an orchestra.
The musicians all play together, and they make beautiful music.

The conductor leads the orchestra.
He or she stands in front of the orchestra and conducts the music.
The conductor makes sure that all the members do their jobs at the right time.
This lets them play in harmony.

Most orchestras play classical music.
They might play music by Mozart or Bach.
But some play operas or pop music as well.
