Do you have questions about developing relaxed violin posture? Here are a couple tips for you, but feel free to comment and ask me any questions you might have. -Suzanne from Violin Tutor Pro
1. Be sure your violin is parallel to the floor and supported by your chin, not your left hand.
2. Sit or stand up nice and tall, check that your left arm is not resting into your side, this is a common posture problem.
3. Keep a close eye on your right shoulder, it should be down and relaxed, don’t let it come up when playing up bows.
Hi Shiroi98, Glad you are practicing in front of a mirror, that is excellent! I like to balance my weight evenly between my feet. When I was first learning to play, the teacher I had at the time suggested an L shaped stance, resting back on the left foot. Throughout the years, and many professional teachers, I have concluded that we should be able to stand, just as we normally would, even while playing the violin. There really shouldn’t be any noticeable difference in your posture, other than the violin extending from your shoulder. Hope that helps!
