Which instrument family includes violins and cellos?

The instrument family that includes violins and cellos is the Strings family. This family is characterized by instruments that produce sound through the vibration of strings, typically made of either gut, steel, or synthetic materials. Both violins and cellos belong to this category, along with other instruments such as violas and double basses.

In the Strings family, the instruments are often played with a bow or plucked with fingers, which contributes to a wide range of musical expression. They are prominent in various ensembles, including orchestras and chamber groups, and are integral to both classical and contemporary music genres. The strings family's unique tone quality and diverse range allow it to play melody, harmony, and accompaniment, making it a foundational part of Western music.
