小鼓, or "xiao gu," is a traditional Chinese percussion instrument. It is a small drum typically made of wood and covered with animal skin. The drum is played with two sticks and is known for its sharp, crisp sound, which adds rhythm to various forms of music and dance. In Chinese culture, 小鼓 is often used in folk performances, festivals, and theatrical productions, such as 京剧 (Peking Opera). It plays a vital role in enhancing the emotional expression of the performance and is an essential component of traditional Chinese music ensembles.
