The pipa is composed of six phases and twenty-four frets, which form the twelve equal temperaments with a wide range. The first string is steel wire, and the second, third and fourth strings are steel rope nylon winding strings. The sound of the pipa is very special. Its overtone ranks first among all kinds of musical instruments in ancient and modern China and abroad. It not only has a loud volume, but also has a crisp and bright sound quality. At the same time, the fundamental tone of the pipa is accompanied by rich overtones, which can make the sound of the lute attenuate less during transmission and have strong penetrating power. When playing in a calm open space, use it to play heavy tones. The sound of the piano can be transmitted two or three miles away.
High-quality pipa sound has strong penetrating power (small attenuation and long distance transmission). The treble is bright and rigid, the midrange is soft and smooth, and the bass is solid.
