Well, guys, I raised this question its because, people kept telling me or asking me whats the right tempo when play the mazurka.....heeeee. I just listened to Rubeisteins op7/1 vivace and his op33/2 vivace. I want to see if he interpret it the same as in tempo.....Obviously he played the both different. Op7/1 was much slower piece. BUT on the otherhand, I listened to Ignaz fremen(I spelt wrong). He played a much faster than Rubeins in op7/1. Now, I dnt want get invoved judging there playing simply because they are masters. these just a TWO differnt pianist at there own interpetation.....ARE you telling them that Rubein you played TOO slow?? or to Freeman, you played to fast???? of couse not. Its back to my point that it seems , when your are famous, you have your own rules and tempos and I am sure no one dares to say anything unless you are BETTER ??/ So, I have reached my own conclusion that the right tempo is when youre enjoying the music and free of mistakes....keep youself away from outside world, you have your own art, which is pure in soul....... whats your say???
