What section of the orchestra is considered the foundation because of its unique timbre?

The string section of the orchestra is often considered the foundation due to its unique timbre and versatility. Strings, including violins, violas, cellos, and double basses, produce a rich and warm sound that can blend seamlessly with other instruments while also providing melodic and harmonic support. Their ability to play both softly and powerfully allows them to anchor the overall sound of the orchestra.
