In China, there have been many attempts at creating variations on the cello (and bass) to fill out the string section of traditional Chinese Orchestras. The èrhú (二胡), an ancient instrument that likely originated in Central Asia nearly a millenea ago, probably has the quintessential “Chinese sound” that Westerners imagine when they think of Chinese music though I’m sure a close tie would be the sound of the gǔzhēng (古箏).
The instrument in the photo to the left is a géhú (革胡). As Brandon Voo states:
The Gehu comes in two sizes, the Da-Gehu (large) and the Diyin Gehu (bass). In a Chinese orchestra, they take the same roles as the cello and double bass in a Western symphony orchestra. The four strings of both sizes are tuned exactly like the cello and double bass and are attached to a machine head with gears.
The wikipedia article for the géhú states that it was “developed in the 20th century by the Chinese musician Yang Yusen (杨雨森, 1926-1980)” which I’ll have to confirm once I do some research but given the time frame referenced by Brandon Voo in his article regarding the changes undergoing Chinese Orchestras during the 1950s, Yang Yusen’s dates would fit in fine.
Here’s what the géhú sounds like:
