*Advice needed* I just found out that I've been holding my violin incorrectly for the past five years
So, like the title says, I just figured out that I have held my violin incorrectly for the past 5 years. For context, I have participated in orchestra classes since 3rd grade. I’ve always liked the orchestra teacher, but they have never seemed interested in actually teaching valuable skills to the class. Not many students care about participating, so I am among the best in my class. This is by no means an accomplishment, nor am I a fantastic player, but I have always loved classical music and want to become better at my instrument. So, since my way of holding my violin has never been corrected, I always assumed that I was doing it right. Until yesterday.
Yesterday, I decided to begin learning vibrato to be more prepared for the material in the upcoming school year. I watched several tutorials with the growing realization that I hold my violin with my arm while I am supposed to have been supporting it with my shoulder/chin. How do I fix this? 5 years of practicing the wrong technique is kind of hard to reverse, and I don’t want to fall behind in class because of my stupid mistake. I’m sorry if this post doesn’t make much sense. I’ve been panicking about this for hours and need advice. Thank you!
