EmmaNoelViolinist, thank you for sharing! I love this song so much! You made me want to make a video of this song to post here 😉 So as for feedback, you have received some good suggestions above my post that you can work on. Meanwhile, I’ll try something that hasn’t been said. I saw a hint of a budding vibrato and I wanted to give you some ideas for developing a relaxed, open vibrato. Right now I see you are using a shoulder pad, and positioning the violin in a good place on the shoulder. The left hand seems to be functioning properly with no technique issues to iron out. Your vibrato is what is called a ‘finger vibrato’, which is where the player applies more, then less, pressure of the fingertip on the string. Of the three types of vibrato, this one is the one that is not desirable. The small action of changing the pressure of the fingertip on the string, causes the pitch to go fuzzy, then clear and produced a ‘false vibrato’ so let’s fix it.
I prefer a vibrato that originates from the wrist, with the hand rolling toward your nose and away from your nose; more specifically just under the note and then to the note, never above. To achieve this, you are all set up for an easy execution of this technique. All you have to do is release the base of the first finger from touching the violin neck. Some people find this very hard to do, even when the head is securely holding the violin. So I suggest practicing easy pieces with this in mind. Touch only the thumb to the violin neck, and the finger tips. Keep the base of the first finger free. In fact it can touch the neck during a proper vibrato, but it must slide on the neck with the ‘waving motion’ of the hand, so practicing with this part of the hand not touching but staying close, is a good first step toward developing a proper vibrato.
Feel free to message me if you have questions about my comments. And thanks for sharing your talent with us!
