Violin Musical Tone Analysis Using Robot Finger

This paper introduces a study to improve the performance of robot finger for violin fingering. The authors have developed violin-playing robot system. Also, authors have designed robot hand anthropomorphic type for the violin fingering. The violin fingering plays an important role in determining the tone or sound. Whether the performance sound produced when the developed robot finger presses the strings of the violin is identical to when a human violinist presses the strings requires verification. The researchers propose utilizing the precedent sound quality rating system to analyze the performance sound of a human violinist and create the conditions needed to produce the accurate quality sound. On this basis, the researchers compared the performance sound made by the fingering of a robot finger with that of a human violinist and suggest a strategy to make improvements to disadvantages.
