Abstract

An automatic evaluation system for musical performances of keyboard instruments has been developed. The system incorporates a music synthesizer and a mini-computer. The system is not restricted to music which has a particular musical beat but is designed for general musical compositions. The computing section of the system accurately calculates the key position, the on and off time of the key touch, and its duration. The analysis section of the system compares a just completed performance with a previously completed correct rendition. Two kinds of information are provided for feedback. 1. (1) Where and how to correct the practised performance; 2. (2) A holistic and numerical evluation of the performance. The system provides identical instructing information on the disparity of tempo as that provided by a trained music instructor for a beginning learner. Moreover, in comparing the analyses of performances for beginners and veterans, we could see the improvement of an individual student with practice. In addition the objective and distinct difference of performing techniques among various players was identifiable. These data agreed with our expected results.
