The bipa is a pear-shaped lute that is a traditional Korean musical instrument. It is derived from Chinese pipa and was introduced through the Silk Road to Goguryeo and Silla. There are two major types of bipa: the four stringed dang-bipa and the five stringed hyang-bipa. While dang-bipa was a Tang-style pipa first introduced from the Chinese Tang dynasty and localized over time to have Korean characteristics, hyang-bipa was created in the Korean Kingdom of Silla. The instrument is also related to other derivatives such as Vietnamese đàn tỳ bà and the Japanese biwa.
