Practice Support for Violin Bowing by Measuring Bow Pressure and Position

Abstract

The violin is one of the most popular musical instruments. Various parameters of bowing motion, such as pressure, position, and speed, are crucial for producing a beautiful tone. However, mastering them is challenging and requires extensive practice. In this study, we aimed to support practice of bowing, focusing on bow pressure. First, we compared the bowing movements, specifically bow pressure, bow position, and bow speed, of eight experienced players with those of eight beginners. Next, we developed and evaluated a visual feedback system that displays bow pressure to support practice. We taught the identified differences to 14 beginners, dividing them into two groups: one practiced with an explanation, and the other with both an explanation and a feedback system. These two experiments found that clarifying the characteristics unique to experienced players can support practice.
