At a first glance,
it looks only like exercises
for the fingers
but in reality it was
a new preparation for the concerto.
Each finger has its importance
and its own structure
that’s why you have to respect it
in order to use it
with a new fingering
that it was unexpected
even for the classical approach.
It was another proof
that it was possible
to innovate
in the new cycle
because the background was
totally different
but compatible
with the continuity
and the duration
of the history of Mankind
and the strategy of Time
as a perfect match.
