This article examines the theory of consonance and dissonance in music and the history of this issue research. Also it featuring the modern theory, which is based not only on common mathematical and physical laws, but also on the biophysics and neurophysiology. An important aspect of the modern theory is effect of the evoked otoacoustic emission (EOAE) and "critical band” (or “frequency Channel”) on the formation of auditory sensations. Previous theories allowed only qualitatively assess the degree of consonance. for the first time proposed a method quantitative evaluation of consonance of any musical intervals. Quantitative evaluation of consonance based on consumption of bio-energy, expended by human in the process of determining the height interval of sounds, subjective harmonics and combination tones.
