"The Theory of Resonant Fractal Musicalization – YSSO" is an original scientific and artistic framework developed by Yankel Soares Suassuna de Oliveira (YSSO). It proposes a new model of musical perception, composition, and pedagogy based on the interaction between cosmic vibrational structures, golden ratio harmonics, and neurochemical states. Integrating quantum energy principles (EQC), neuroacoustic phenomena, and harmonic fractals, this theory creates a multi-dimensional system for musical resonance aligned with human emotions and consciousness. This Volume I establishes the foundational principles of the YSSO system, including: Fractal scales based on golden proportion Expanded modal systems (YSSO Modes) Neuro-harmonic correlations and emotional modulation Custom tunings for new musical instruments Applications in neurotherapy, cosmic acoustics, and musical education This work is protected under an international intellectual property clause with 12% royalty on any derived publication or commercial use.
