I like this piece very much as this is the only choice of rhythmic character for the whole list C. But I found it extremely hard to play the Mordent on top of the right hand octave. In their first appearance, I can manage it by playing the lower octave note by the left hand and then I can play the ornament at ease. However, when it comes to the middle section, the trick cannot be applied again as the left hand plays a 10th with the right hand in that sense. If my hand is really too small, can I simply skip that mordent?

Any suggestion?
