I believe the novella is the perfect form of prose fiction. It is the beautiful daughter of a rambling, bloated ill-shaven giant (but a giant who's a genius on his best days).
If I could write the perfect novella I would die happy.
Presenting Aschenbach as a composer - based on Mahler - leads to some dreadful scenes (especially those in which Aschenbach is berated by his student), and it surely distorts the character Mann created. Yet, we know that Mann's novella was based on a holiday in Venice he took with his wife and brother, and that while he was there he followed the reports in the German newspapers, describing the dying Mahler's progress as he returned from New York to Vienna.
Twitter is most suitable for me. In the Chinese language, 140 characters is a novella.
I thought about starting a novella club because it seemed less ambitious.
