abstractr Many morphing methods for image, speech and musical tone have been proposed. But no mor-phing method for musical song have been proposed. In this paper, we propose a morphing method
for musical song (one measure, 3 tracks) by parallel processing of musical components - timbre, contour, rhythm and harmony. We analyzed questionnaire data about the similarity of components bymultidimensional scaling and Neural Networks, and got psychological similarity map of each musicalcomponents. We got musical morphing by re-synthesizing morphing results on the similarity map ofeach musical components. By experiments, we succeeded to get satisfactory morphing results.
