Which statement correctly describes the term 'orchestra'?

The term 'orchestra' refers to a large ensemble that typically encompasses a diverse array of musical instruments, including strings, brass, woodwinds, and percussion. This diversity allows orchestras to perform a wide range of musical compositions, from classical symphonies to contemporary pieces. The inclusion of various instrument families is a defining feature of an orchestra, enabling a rich and multilayered sound that is characteristic of orchestral music.

In opposition to the other statements, the nature of an orchestra is not limited to just brass and woodwind instruments or focused primarily on string instruments. Additionally, orchestras are typically conducted by a conductor, who plays a vital role in guiding the ensemble, ensuring cohesive performance, and interpreting the music. This leadership is essential for coordinating the many musicians and their diverse roles within the orchestral framework.
