Sunday practice

I'm videoing myself using my iPhone. I have played all four songs that I know from the Suzuki book 1. I'm watching for bow angle, bow am elbow movement and stiffness of my bow hand and how the sound changes in relation to those things. Also looking at how the bow skates sideways on the strings sometimes.

New practising

I'm learning the violin. I have had three or four lessons now. Sometimes, like tonight, the practising goes haltingly. All my skills of three weeks are gone and I can't even play a single string without crossing over the next one beside it.
In my lesson I am compelled to play everything extremely carefully. Which is boring to listen to. And then I get playing-for-the-teacher anxiety which makes the bow jump along the strings due tension in my arm or shoulder or whatever.
