Pressure, motion, gesture and the coordination of all these parameters is an important task in musical instrument playing, exercising and teaching. New sensing and feedback technologies provide many possibilities to support the teacher and the student in the complex learning scenarios. In this paper we show with some practical examples the application of our current sensing technologies to teaching and everyday self exercising of violin. This starts from a left hand and chin pressure sensing method for coordination and position change analysis, a setup for force measurement and the weight allocation between the chin and left hand while playing, and a left and right hand thumb position and bending measurement method. Different individually adapted feedback methods allow assisted teaching in teacher-to-student tuition and also efficient training in single exercising situations at home without a teacher. But also in combination with audio, video, and gesture recording, our setup is useful for accurate offline music sheet alignment and analysis. Especially studies of complex movements as well as finger position and force distribution changes can benefit from this approach. We discuss the practical applications regarding the recognition of inaccuracy, cramping, and malposition.
