Off-Rhythm Detection System for Beginner Violinists

It is important for beginners to know how to play a violin in general and how to play it correctly in particular. Maintaining rhythm is very important for progress, especially in violin playing. If a system that allows beginners to easily receive feedback on rhythmic deviations in their own play can be implemented, it will contribute to the improvement of violin players' skills. In this study, we present a method for detecting off-rhythm in beginner violin players. This method uses an onset envelope to estimate the rhythm of a teacher's performance prepared in advance, normalizes the teacher's performance and the user's own performance, extracts rhythmic features using tempo diagrams, and derives the differences between them. This is a method. By implementing this method, users who are beginners in violin playing can smoothly practice rhythm on their own, using feedback from the system.
