Erhu is a Chinese two‑string bowed lute (a member of the huqin family) whose singing, voice‑like timbre can move seamlessly between lyrical cantabile lines and brilliant, percussive articulations. It is held vertically on the left thigh, with the bow hair running between its two strings, which are usually tuned a fifth apart (D4–A4). As a genre label, “erhu” refers to the solo and ensemble repertoire centered on the instrument—music that ranges from folk‑derived melodies and opera idioms to conservatory‑style concert works and contemporary fusion. Its melodic language draws heavily on pentatonic and modal materials from various Chinese regional traditions, while modern compositions expand technique, form, and orchestration for Chinese orchestra and mixed ensembles. The instrument’s expressive palette—portamento, nuanced vibrato, ornamental slides, wide dynamic range—gives erhu music a distinctive capacity for lyrical narrative, tender intimacy, and dramatic storytelling.
