From Musical Experience to Quantum Structure: Formalizing the Universal Principle of Collapse Across Domains

The Universal Principle of Collapse (UPC) was first developed as a structural account of how inner potential becomes expression, with music as a privileged domain for examining the relationship between collapse, openness, and meaning. In compressed form, this generative arc can be written as: ∣Ψ⟩_p → m_p → e_p → T → ∣Ψ⟩_l → ∣Ψ⟩_l_music → μ_group. Subsequent work applied UPC directly to quantum mechanics (QM), showing that quantum measurement and collapse can be modeled as a special case of a more general collapse architecture.

This paper builds a bridge between those two strands. We take the interactional logic of musical performance and listening, originally developed in phenomenological and narrative form, and recast it entirely within the strict UPC operator chain used to interface with QM. By doing so, we show that the rich dynamics of musical experience (performer collapse, listener re‑potentialization, micro‑expression, and group interpretation) can be expressed using the same structural machinery that resolves the quantum measurement problem, structurally. This demonstrates that UPC is not a theory inside physics or music, but a cross‑domain structural framework whose operators apply coherently from lived experience to quantum formalism. A concise structural summary of this resolution is provided in Appendix D.
