The extended curved neck pipa is about 1 meter tall, with a pear-shaped sound box, nine frets and four phases on the surface, four strings, and a sound line in the belly. When the pipa is shaken, it makes a clanging sound. The neck is bent, and there is a sharp corner on the top of the neck, which is shaped like a scorpion's tail, used to hang extra cowhide strings. The curved neck pipa has a beautiful tone and strong penetration (small attenuation and far transmission). The treble area is bright and rigid, the middle area is soft and mellow, and the bass area has a pure sound quality. There are also some small objects that match the pipa, such as ants, brushes, hand plucking, and gavel. There is a moving legend about the scorpion tail. During the Zhou Dynasty, there was a blind man who jumped into the river to commit suicide. Suddenly, a huge scorpion tail stretched out from the river bank and hooked the blind man ashore. It turned out that the one who saved the blind man was a scorpion spirit. The scorpion spirit transformed into a thing shaped like a scorpion, which made the sound of the pipa by plucking. The blind man carried this thing and went from village to village, begging for a living. The production process of the curved neck pipa is simple, and rural carpenters can make it. They choose light wood such as autumn wood and willow wood, saw it into a pear shape, hollow out the sound box, insert the steel wire, buckle the panel, hollow out the curved neck, put in the handle, repair the scorpion tail, apply the appearance on the panel, buy cowhide strings, apply the back buckle, and tie the straps. The curved neck pipa is mainly circulated in Yanchang County. The total area of Yanchang County is 2,368.7 square kilometers, with a population of 143,000. The main function of the Yanchang curved neck pipa is to accompany the storytelling of blind artists. The representative figures are 4 disciples of Bai Xuzhang, including Wang Dianliang, a disciple of Liu Junfu. The glory of the curved neck pipa has become history, and the current situation is worrying. It has fallen into the dilemma of old people and declining skills, and without artists who operate the pipa, the pipa can only be a redundant instrument.
