What is an Erhu?

An erhu is a traditional two-stringed bowed instrument commonly used in Chinese music. The instrument has a long vertical neck and a small resonating soundbox, usually covered with python skin, which helps produce its distinctive tone. Unlike many Western string instruments, the erhu does not have a fingerboard, so the player presses the strings with their fingers without touching a solid surface beneath them.

The erhu is played with a bow that is positioned between the instrument’s two strings. When the player moves the bow back and forth, it causes the strings to vibrate and produce sound. The musician changes pitch by adjusting finger placement along the strings, allowing for smooth slides and expressive pitch changes that give the instrument its emotional character.

The erhu is widely used in Chinese classical music, traditional ensembles, and modern orchestras. Its sound is often described as expressive and vocal-like, capable of conveying a wide range of emotions. Today, the erhu remains one of the most important traditional instruments in Chinese music and continues to appear in film scores, cultural performances, and international musical collaborations.
