This paper specifically targets violin learners who are working on their pitch accuracy. We employ a pitch tracking algorithm to extract the pitch played. Through volume thresholding and region detection, only parts of frames are processed. So our system can provide real-time feedback to show violin learners whether they played the right pitch. The system also provides the major scales and arpeggio scores as teaching materials, and violin learners can choose different tempos to practice, depending on their level. The user-friendly system interface allows violin learners to easily perceive the pitch differential between the pitch of the target note and the pitch played, allowing users to precisely adjust their playing. The statistical feedback records progress and analyzes error patterns, enabling violin teachers to evaluate student progress precisely, and correct common error patterns effectively.
