Hello! Firstly I'm really grateful for your such an detailed comment and your some critical remarks, too! It gives me an a great opportunity to say more about this piece based on your remarks.
This high speed beginning I can explain this by the fact that it is precisely this that is the reason for the funebre march. funebre marches are often associated with consequence of war (in this case, it is exactly so)...And this piece ends in the same way that in spite of any losses and disasters people continue to fight with each other. This is the core of this prelude. Despair and misunderstanding, the inability of people to negotiate with each other. Willingness to make any sacrifices if only to remain right. Rightness is the biggest and most harmful drug that everyone actually possesses, but for some reason everyone wants his truth to be better than the other.
As for the melody of the march, or rather its lack, I want to say that the march is for me here as a recitative, as an appeal / revelation to the listener. It is divided into phrases, they have their own dramaturgy. And when the words end and the world can no longer withstand the pressure and onslaught - again all overwhelmed by the same war, selfishness, the road to nowhere.
About 44 and 45: I just needed to free up space for the impending contrast, but at the same time not only stay the tension, but also strengthen it. Therefore, I removed the harmony and left the gap between the recitative and the impending end.
And thanks again for your support and this comment!
