Hello Basschatters,
 
	I would like to ask for some advice please.
 
	When playing pizz at a reasonably fast tempo for me, I guess about 140bpm plus, I get cramp in right hand. It usually starts after a few songs, and hits about a minute into any song. At the same time my hand tries to make itself into a sort of claw shape. 
 
	Once cramps start I find  it is hard to make a nice note, or a note at all even.
 
	I have cramps generally, so it may just be me, but I wondered if there is any technique, practise or tricks that might help .
 
	I have attached a vid of my right hand so you can see my technique, what there is of it. Apologies for lapses of tempo and intonation towards the end.
 
	Any advice would help a lot.
 
	Thanks
 
	Peter
