The orchestra's four sections: strings, woodwinds, brass, and percussion are referred to as the "Four Sections."
It also refers to the piece's four movements: slow for strings (accompanied by woodwinds and brass), slow for percussion, moderate for woodwinds and brass (accompanied by strings), and quick for the entire orchestra.
A string orchestra is an orchestra that only has a string section made up of bowed strings like those used in Western Classical music.
When a classical orchestra takes the stage, the strings are first, followed by the woodwinds, brass, and finally the drums.
