Characteristic analysis of cello performance sound and examination of acoustic information for improvement of performance technique

Abstract

We studied the differences in performance between beginners and expert musicians by taking cello performance as the object of our research. We found the two differences both performance technique (bow motion) and playing sound between beginner and expert players. Improvement of bow motion by learning textbook on basic cello performance reduced the “husky sound” at the start of playing. Next, we created effective sound information based on the envelope of playing sound of expert players. We conducted experiments in which subjects used this acoustic information and were led to become more proficient on both envelope and frequency characteristics of playing sound.
