On September 30, 2009, Minji Kim, traditional percussionist, dancer, and a Republic of Korea 2009 Korean Traditional Artist-in-Residence, performed an evening of folk music on the changgo, an hourglass drum at the heart of traditional Korean music. The night's program began with an introduction by Dr. Ju-Yong Ha, composer and ethnomusicologist, who also provided commentary before each of the three musical selections: a kayagum sanjo, a duet for haegum and changgo, and a solo percussion piece for changgo. Minji Kim was accompanied by Gee Sook Baek on the kayagum and Lee Kyung Kang on the haegum.
