“Lamenta,” the longest series in Myung Mi Kim’s fourth collection, Commons (2002), is structured after the metonic cycle, a calendrical unit of nineteen years. A lunisolar measure, the metonic cycle encapsulates the notions of simultaneity, equivalence, and difference. It is the “period of whole days over which the visible lunar and solar periods almost resynchronize” (Dictionary of Weights and Measures). This re-synchronization suggests a confluence between two different measures of time, which can be identified without subsuming one order of measure into the other. Importantly, there is a remainder when these two cycles nearly meet: “the difference between the 236 synodic months and 19 mean tropical years is barely two hours.” A portion always exceeds.
One of the ways an experience of time is produced in poetic contexts requires engaging our body's memories, such as how we hear a sound. The way sound decays in a space, or how it moves and dimishes across a duration of time, engages our ability to take note of the unfurling present moment. It's a particular attention, fixated on a deeply embodied phenomenon that reinvigorates our ability to locate ourselves in the world. To invoke a sound is to invoke the body in present time.
I find this link between sound, the present, and the body richly explored by Tan Lin's digital poem, “Echo,” archived at UbuWeb. An echo reflects sound waves back to the listener, often in a diminished manner.
