The title refers to an ancient (perhaps apocryphal) ritual, performed over 2,000 years ago, that sought to connect earth to heaven.  A ceremony was held, full of music and dance, in which it was said that “the sound of drums outreaches heaven.”  One can see how the idea of this ancient ritual may be connected to modern shaman rituals (굿) still prevalent throughout Korea today.  The piece draws on the innate rhythmic tension and frequent hemiola of Korean jangdan (장단), or traditional rhythmic patterns, while not literally relying on existing patterns.  Musically, it imagines a place beyond the heavens, where the sound of ancient drums is still heard, echoing not only across space, but also across time.
