Hi all,i just finished Bach WTC I - Prelude & Fugue 2 , Chopin Mazurka Op.68 no.2 and Scarlatti Sonata K009.So my next goal is to learn this beatiful valse. It has been always my desire to learn it sometime My only problem are the jumps of the left hand.My accuracy is good but i feel fatigue after a while. So do you have any suggetions how to gain the stamina and relaxation to play it? Should i concentrateon the lateral movement of the shoulder and forearm and keep my wrist as supple as possible?Thanx!PS: This forum rocks
