First off… that is not the key of D♭. That… is not as much a key signature as it is someone throwing a flat on the staff and calling it a key signature. Secondly there are 4½ beats in the first measure…. 7 beats in the second measure and somehow simultaneously 5 beats and 6 beats in the third measure… according to the time signature there should always be 2 beats in each measure. Finally, with all the minor seconds the prelude du Fornication apparently sounds horrible.
