Down with mazurkas and waltzes

I think that any composer that makes your uncoordinated left hand leap across the keyboard from a open octave position to a scrunched together chord position should be punished. I'm accompanying Michael for his Grade 3 violin exam. Two of the pieces are fine; one is a mazurka. Grrr. Next time I am asked to accompany I will first ask "is he playing a mazurka?" and then answer accordingly! Oh well, I suppose it is good practice for me.
