Intro to Quantum Harmony: Chords in Superposition

Correlations between quantum theory and music theory—specifically between principles of quantum computing and musical harmony—can lead to new understandings and new methodologies for music theorists and composers. The quantum principle of superposition is shown to be closely related to different interpretations of musical meaning. Superposition is implemented directly in the authors’ simulations of quantum computing, as applied in the decision-making processes of computer-generated music composition.
