A Real-Time Fingering Detection System for Contrabass Using Musical Rules

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.
