2. Description

 Equinox refers to the moment when the Earth’s equator crosses the center of the Sun, marking the spring and autumn equinoxes. It is also a boundary where even the smallest difference in time can shift the balance between two states. In this work, the equinox is interpreted as a metaphor for an unstable equilibrium—an environment in which even the slightest vibration or disturbance can generate waves.

 All ecosystems operate within such conditions. The skin and breath of living beings are never reproduced in exactly the same way from one moment to the next. Like air currents constantly moving from one place to another, continuous vibrations sustain ecological structures. Similar to the movement of waves on the surface of water, temporal variations produced by elements with different degrees of curvature form a fundamental principle through which ecosystems maintain themselves.

The installation translates this principle into sound through the interaction of sound objects undergoing different frequency transformations and through the contrast of their sonic textures.

 Eight speakers installed in the space emit sound in two distinct groups. The first group is structured around the five-tone scale of Korean court music (Aak). The second group consists of sounds recorded in real time through microphones placed inside and outside the exhibition space, which are then transformed through audio processing. The first group generates pitch variations and produces beating frequencies that emerge between adjacent frequencies. As visitors move through the space, the frequency bands in which these interferences occur continuously shift; when movement ceases, the sound gradually returns to a more stable and clearly defined tonal structure. The second group of sounds also responds to the movement and position of visitors. The locations from which sounds emerge change dynamically, while variations in frequency and volume envelope allow the sound to follow the visitors’ trajectories through the space. When no movement is detected, the system returns to the original recorded state, and a single sound sample is randomly played from one of the speakers.

 As suggested by the title Equinox, these two contrasting sonic structures—a pre-composed musical framework and the complex timbral textures of sounds occurring spontaneously in the environment—interact through audio processing. Their continuous mixing and transformation produce a shifting sonic field that moves between instability and clarity. In this way, the work reveals the organic nature of a space where energy continuously evolves together with the presence and movement of the audience, forming a dynamic continuum.
