A Multi-Dimensional Analytical Model for Musical Harmony Perception

In this paper, a theoretical approach is presented to analyse music harmony perception under different tonal context. The purpose of this study is to account for the empirical perception rankings of musical chord structures. We believe the perception of a musical simultaneity depends on both its internal structure and external tonal context and the failure of previous psychoacoustic theories possibly comes from the ignorance of tonal context. The model prediction result reveals some important insights in line with empirical observations for music triads.
