Left Wrist Says Ouchies Again!

I tried to play Jeux Interdits part 2, forgetting to warm up beforehand. What did I get? Minutes' worth of ouchies!

A few pointers on correct left hand position -- correct being not just a matter of following strictly formalist classical playing; rather, a matter of warning to those who do not wish any unpleasant, painful sensations while playing.

Take a close look at the thumb position. The thumb should never - evah! - cross the palm, or else pressure when pressing the fingerboard will fall on the median nerve, a primary ingredient for wrist pain. Instead, do:

 

... pull your thumb out and away from the palm. Playing this way will also force your fingers to lean towards the left, making bars easier for both index and middle fingers.



PS. My MS Paint skills are once again put to the test!
