Shoulder rest for me is essential. Since I was in elementary, I have difficulty playing the violin. I cannot tuck the violin under my chin very well and sometimes it would slip as I cannot shift my fingers well. Not until someone lent me her shoulder rest and which helped me play well. Though I knew it limited the sounds that I produced. But everytime I would go to play the violin even just to practice, I can't stand without my shoulder rest especially with pieces having lots of shiftings. But now I'm trying to work it out not to use shoulder rest, even though it's hard for me.
Could you please give me some advice? How much would it affect my playing?
