Even if so, would it really matter? Cadenzas can be so beautiful, and
they always have one wonderful advantage which is that they allow us to
hear the sound of the instrument solo. When I appreciate the concerto,
it is an additional joy.
Do you think it is rationally possible to generalize about such things?
