In the below image, the two characters underlined don't seem to have a match in the character map program I'm using:
The closest matches I can find are п and д, respectively. Are these indeed the matches, and if so, are those in the image perhaps archaic, obsolete, or simply an alternate form of those letters?
P.S. This text was the heading to a music score of Sergei Rachmaninoff's famous Prelude in C♯ Minor, Op. 3 No. 2.
