The proposed Quantum Core Sonification (QCS) of the Quark-Gluon Plasma (QGP) represents the foundational technical and artistic layer for the 'Galactic Score' project. This layer is strategically designated as the "opening movement" of the entire composition , establishing the initial conditions that dictate all subsequent sonic developments. The design rigorously integrates high-energy physics data with computational synthesis, fulfilling the project’s overarching goal of rebuilding the "music of the spheres" using 21st-century physics and synesthetic interfaces.
