Abstract
This chapter explains the various aspects of tone sensation. Sound consists of two simple tones: consonance and dissonance, which are often referred to as “tonal consonance― and “tonal dissonance,― respectively. They refer to the perceptual singularity of complex-tone intervals with simple frequency ratios along the continuum of all possible ratios, without any reference to a musical context. The dependence of tonal consonance on frequency ratios can be demonstrated more quantitatively by considering the total dissonance of a particular interval as the sum of the contributions of every adjacent pair of partials. The amount of dissonance of a single pair of simple tones is related to the width of the critical band. On an average, the tonal dissonance is largest for about a quarter of the critical band. The total dissonance score of the interval varies with the fundamental frequency of the higher tone.
