Description
Just joking, of course! As far as I know, Martha Argerich never did this kind of exercise to develop her technique. This is actually an excerpt from a piece named "The Target", by Russian composer Leonid Desyatnikov. The 2nd movement of this composition, "At the races", incorporates a Hanon exercise in a very original and funny way.
