But then Cortot had the same opinion:

The Goldberg Variations are pretty, another beauty than Mozart.  The
only thing is that are 30 variations, 30 beauties and one theme (also
beauty, maybe the most).  I realize that in piano it can result difficult
to performance but the enthusiasm that provoke to the performer...  it can
evacuate the hardness.
