I want to know the answer to the following question:
To whom did Chopin reveal in letters which parts of his work were about the singing student he was infatuated with?
All the background I'm provided with is that "Tytus Woyciechowski, Jan Nepomucen Białobłocki, Jan Matuszyński and Julian Fontana; the latter two would become part of his Paris milieu.". Is that enough to answer the question?
