The aim of this study is to develop coaching methods for playing a cello by use of sound information. For this purpose, we measured and analyzed the cello sounds both of beginner and professional firstly. As a result, we indicated that the difference of both sounds was form of harmonics. And, we evaluated the degree of difference of both sounds by correlation coefficients etc. Next, we measured both pushing force of string and acceleration of bow of the cello. The differences were recognized among beginner with professional in both force and acceleration. Based on a force-waveform of professional we made the acoustic information in an attempt to improve cello playing skill of beginner.
