If an instrument is regarded as a medium, for expressing the musical thoughts of composers. I believe that we must reveal ourselves through each performance. I proposed to call this idea “a forest named ‘Korean music'” . That consists of small trees and entwining trees. There are tall, beautiful trees deeper in the forest, too. In order to understand this forest, I began to analyze the details, the tiny grass, sometimes the branching creeks, the rock placed around them. Occasionally, I would think that that ornamentation-this group of Korea music-is the main characteristic of the forest, not simply a minor decoration. I thought that the solidness of the Hyangpiri (Korean oboe) and the tenderness and flexibility of the Saepiri (soft tone oboe) seemed to be “arrowroot” entwining the trees of the forests.
