Now the first variation will go pretty well with both hands together; with increasing mastery of it, the requisite shading in the right hand can be produced.

As your right hand is not yet tired, play to me now several times, first slowly and then faster, the passages which I gave you from the introduction.

When the right hand becomes a little fatigued, take a portion from the finale for the left hand.

You may also try over the adagio; but I recommend for your special practice the part for the right hand in the third variation.

You cannot make a mistake about it, if you do not try to play it too fast, and if you carefully observe the fingering indicated.
