How is math able to predict the consonance or dissonance of musical pitches?

In sixth century BC, Pythagoras discovered the mathematical foundation of musical consonance and dissonance. When auditory frequencies in small-integer ratios are combined, the result is a harmonious perception. ... This result indicates a link between consonance and the dynamical features of the signal.

Thus, the consonant octave is characterized by a 1 : 2 frequency ratio between two tones, while the dissonant semitone is characterized by a 15 : 16 ratio.
