Harmony Perception by Periodicity Detection

Frieder Stolzenburg

The perception of consonance/dissonance of musical harmonies is strongly correlated with their periodicity. This can be shown by consistently applying recent results from psychophysics and neuroacoustics, namely that the just noticeable difference between pitches for humans is about 1% for the musically important low frequency range and that periodicities of complex chords can be detected in the human brain. Based thereon, the concepts of relative and logarithmic periodicity with smoothing can be introduced as powerful measures of harmoniousness. The results correlate significantly with empirical investigations on the perception of chords. Even for scales, plausible results are obtained. For example, all classical church modes appear in the front ranks of all theoretically possible seven-tone scales.
