A conceptual metaphorical-analogical correspondence between science and the notion of complex systems applied to the analysis of solo and chamber works by Julio Estrada, Luciano Azzigotti, Samuel Cedillo, and Raúl Dávila

This research argues that certain contemporary compositions—particularly instrumental solo and chamber works—cannot always be fully characterized or understood using inherited musical categories. This limitation arises from the use of heterogeneous acoustic materials, such as noise, which place many traditional concepts—melody, rhythm, form, harmony, among others—out of context. As a result, these categories are largely ineffective for explaining and characterizing many recent sound-based musical experiences.
