Using the first two variations I find that a piano accomp in the lower manual is one octave low. It needs to be raised one octave but I do
not know how to do this.

Can someone tell me if it is possible to raise a accomp. piano up
one octave so it sounds in the correct range?
This would make it sound so much better. Plese help if you have
knowledge to do this. Thanks in advance. Lloyd rocker
