This paper explores the emerging field of Sound Homeopathy and its potential for enhancing brainwave entrainment techniques, particularly through the use of monaural and binaural beats. Current brain entrainment methodologies face challenges in accurately selecting carrier frequencies and accounting for the brain's sensitivity to subtle frequency variations. This paper highlights the limitations of traditional approaches, such as relying on whole-number frequencies and arbitrary carrier selection, and proposes a new paradigm that incorporates fractional frequency variations and psychoacoustic principles. Drawing on harmonic theory and musical scales, the article introduces a model that aligns brainwave frequencies with mathematically related musical intervals, offering a more precise method for frequency selection in therapeutic applications.
