Which element is typically found in orchestral music?

Orchestral music is characterized by its rich and diverse textures, achieved through the inclusion of a variety of instrument families. This typically encompasses strings, woodwinds, brass, and percussion. Each family contributes unique timbres and dynamics, allowing composers to create intricate arrangements and harmonies. The blending of these different sounds is a hallmark of orchestral works, enabling a wide range of musical expression. This contrasts with the other choices, which limit the scope to a single family of instruments, thereby missing the collaborative sound palette that defines orchestral performances.
