An on-line model for Melody Perception 

Home Research

OPTM 1.4 is a computational model for the On-line Processing of Tonal Melodies. It describes the processes a listener executes when transforming a tone sequence into a tonal melody.

• A basic assumption of the model is that a tonal melody is represented in terms of an underlying harmonic progression.
  
• The model implements three primary mechanisms: Key-finding, Chord recognition, and Anchoring.
• The operation of the model and its associated output are displayed while the tone sequence is entered.
• The output consists of the evolving harmonic framework, the assimilation of non-chord tones, the arising expectations, the tones that do not fit, and an overall indication of the goodness of the melodic percept.
