I'm curious about how tough and detailed Saint-Saens is to perform. Is he as fiendish as, say, Rachmaninoff?
Rachmaninoff is surely a devil deliberately cruel to the pianist. Such a satanic intent is shown, for example, in the toccata-like cadenza of his Concerto No. 3, 1st movement that imposes a torturous demand on the dexterity of the performer's fingers. In contrast, the written-out cadenza of Saint-Saens' Concerto No.2, 1st movement is to me one of the easy parts albeit fast and showy and impressive. In other words, their intents are different: one is for the virtuosic display, and the other for the ornamental impact.
In my opinion, difficulty level should not be always measured by dexterity. Sometimes it concerns the demand on the pianist's
brain and magical
touch. For instance, the slow section I gave as an example in my post #170 is something a beginner would say "Hey, even
I can play." Yet, I find it very challenging. It is the part that Saint-Saens demands "
molto espressivo" (very expressive), the ability of speaking one thousand words with just a few notes. Furthermore, the score demands that the bass octaves last at least half of each bar. Well, that's humanly impossible since there is something going on elsewhere that needs the left hand as well. One way is to use the sustaining pedal. The young prodigy Hugo Kitano (

To compensate that, he mindfully made the timber of the call melody drastically different from the answer melody so as to increase contrast and thus clarity. The result is that he produced a velvety section rich in magical tone colors. How did I handle that dilemma? Hehe, I cheated.

Not only did I add pedals, but also in some places I used my right hand to cover some tasks meant for the left hand so my left hand could hold those bass octaves long enough!!! And there are more challenges in that "simple" section. I will not mention them now, otherwise it will be a long thesis.
