Erhu is an ancient traditional Chinese musical instrument with a history of more than 1,000 years. Erhu originated in Central Asia and was introduced to China through the Silk Road in the Tang Dynasty. The name "erhu" encapsulates its essence, as "er" translates to "two" in Mandarin, a representative of the two strings that resonate within its slender frame. With a lineage rooted in the Hu ethnic group, the erhu carries within it the echoes of cultural intersections and historical exchange.

The erhu's elegant form comprises a lengthy wooden neck adorned with two tuning pegs that cradle the duet of strings. The lower portion of the neck gracefully merges with a resonant sound box, which is clothed in the supple skin of a python. This unique marriage of elements contributes to the instrument's distinctive timbre and profound resonance. At the heart of the erhu's harmonious conversation lies the bow, poised tenderly between the two strings. This bow, composed of resilient horse tail hair and bamboo, channels the musician's intentions into melodies that transcend time.

The erhu is almost always tuned to the interval of a fifth. The inside string is generally tuned to D4 and the outside string to A4.

Erhu is mostly used to play traditional Chinese music, but now more and more excellent musicians use erhu to play different types of music and bring it to the international stage.
