Great masters of the violin achieve outstanding results with different techniques of controlling their instrument. Each production of music is technically correct if it does not harm the body. The Physioviolin chin rest is designed to help the user learn a safer yet technically perfected posture that reduces the harmful effects of a forced posture and is most effective in the stage of acquiring the right playing technique. Instead of trying to find the most comfortable position on the chin rest, it is better to use the head correctly only when necessary. The chin rest is not a sofa.
