Abstract

A new theory of musical tonality is explored, which treats the central auditory pathway as a complex nonlinear dynamical system. The theory predicts that as networks of neural oscillators phase-lock to musical stimuli, stability and attraction relationships will develop among frequencies, and these dynamic forces correspond to perceptions of stability and attraction among musical tones. This paper reports on an experiment with learning in a model auditory network. Results suggest that Hebbian synaptic modification can change the dynamic responses of the network in some ways but not in others.
