Believe it or not I haven't read that book...

If I need a 1/2 size I know where to come LOL
Lesson 7 today (is that all?) and he's happy with my progress...
Today he gave me a great exercise to work on both LH and RH together but separately and be able to concentrate on everything together: 1 finger scale of 4 octaves but very very slow:
Start at heel. Get LH in a good position, all fingers curved etc. Place RH, check knuckles, arm relaxed, wrist down etc. Move the bow 5 cm at a time, watching RH position all the time and altering towards point. THEN pause...move 1st finger to next position, check LH position, elbow, fingers etc..then forget LH and concentrate on RH on the up bow, 5 cm at time, bringing hand back to flat position etc.
It was brilliant as it gives time to watch everything. Think it's going to help a lot this week.
2nd exercise was 1 finger scales again (with slides between shifts), but this time quicker at the heel only (10-15 cm bow) to try to smooth up my bow changes. Found out I'm speeding the bow a little at the change and that's what is giving the crunch. So less speed and a little less weight and hey presto! Now just got to practice it in.
Oh and I paid for my violin so she's all mine now! Now what to call her???

Walking with my light case today was fantastic, what a difference!
Next lesson in a week's time...which gives me more time to be able to practice everything else!!
