Abstract
Fingering is one of the important aspects in contrabass performances because it affects contrabass players’ musicality. If contrabass players share the real-time fingering of the performer, it helps them for learning professional contrabass performances. In response to these requirements, the goal of our study is to construct a real-time fingering detection system for contrabass players. Our system achieves the real-time fingering detection by integrating a simple camera-based image detection and musical rules. We have developed a prototype system, and evaluated its effectiveness by actual use of the system. The evaluation results confirmed that our system detects fingerings in 96% accuracy.
