This paper presents a two‐stage model that calculates tonal context as a continuous function in time. The model is capable of processing acoustical polyphonic inputs. The first stage is a simple note recogniser that produces pitch‐class note output corresponding to the acoustical input. A bank of leaky integrators constitute the second stage. The integration rates and saturation limits of these integrators vary with each musical event according to the relations among input notes and the candidates of tonal centre. User controllable parameters enable musical memory time span control. The output of the model is the tonal context vector retaining normalised values of the leaky integrators with each integrator holding the strength value of a specific tonal centre
