Zhonghu

It was developed in the 1940s as the alto member of the huqin family (similar in range to the European viola) to increase the pitch range of the instruments used in a Chinese orchestra.

[1] The zhonghu is analogous with the erhu, but is slightly larger and lower pitched.

Composer Jeremy Zuckerman has used the Zhonghu in critically acclaimed shows' music such as Avatar: The Last Airbender and The Legend of Korra.

Specifically, he has said in the podcast Song Exploder that along with the erhu, the Zhonghu was used in The Legend of Korra's series finale music.
