Moving left arm
There should be a straight line from your elbow to your fingers.
When you are going to play on a lower string, you should move the tip
of your elbow forward (swaying it to the right). When you go back again,
you don't have to think about it! The arm will automatically move back,
archiving a less awkward position.
Fingers
The fingers should hang at the freeboard. When you get on to the E-string there should be a small distance between the index finger and the fret board. (On the other strings there is no distance)
Notice the thumb position. As mentioned the thumb is curved. You do not hold the violin with the hand, the violin is held with your cheek.
