Seonsori
Seonsori, also known as ipchang, is a traditional Korean music genre known as "stand-up song." The word of seonsori originated in the word seo-da, which means stand in Korean. Koreans play a game while singing seonsori. The leader, called mogab, starts to sing while playing a janggu and the others sing and play a sogo.
The seonsori is sung and performed with a strong voice and enthusiasm. Singers of seonsori are usually men in order to make it energetic and fun. The seonsoris vary in different localities of Korea such as Gyeonggi-do, Seo-do, and Nam-do.
The best known seonsori is Gyeonggi seonsori. It also influenced Seodo and Namdo seonsoris.
