a distant relative of the Western lute, is one of the oldest musical instruments in the world, first appearing in Chinese texts over 2000 years ago. During the Tang Dynasty (618-907 AD) the pipa became one of the most popular musical instruments in China. Bai Juyi, among the most important poets of that period, vividly described pipa music and its techniques in his famous poem Pipa xing, or "Ode to the Pipa." The Tang Dynasty pipa was larger than the modern version and was played with a wooden plectrum instead of the five picks used today (a technique still used by its Japanese descendent, the biwa, and once used on the extinct Korean pip'a).
The modern pipa is tuned A-D-E-a, with all the open strings sounding below middle C on the piano. It has 30 frets which extend down the neck and onto the sound board, giving it a wide range including all the chromatic possibilities. The technique for playing the pipa is characterized by rolls, slaps, "Bartok pizzicato", harmonics and noises which are often combined into extensive tone-poems. Traditional performers can imitate a wide variety of sounds - from flowing water, conversing geese and trotting horses to Chinese gongs and drums and sounds of battle. Traditional pipa pieces are usually classified as either civil pieces (wenqu) or martial pieces (wuqu). Comparatively speaking, civil pieces are refined and elegant, and played at a slow tempo and soft volume. Martial pieces are generally faster and louder and often depict scenes in historic battles. The pipa is also used in chamber ensembles, to accompany singing and dancing, and is a popular solo instrument.
