Jansy,
Gerard de Vries puts to good use both Hofstadter and Bach's "signed" fugue in his article. I think Gerard's notion is that Nabokov is similarly inscribing his own name in PF via the three main characters. I hope he will correct me if I'm mistaken.

This reference to Bach's death after including in his last Fugue the notes BACH (in the German notation) might fit in with MR's interest in fugal themes and Kinbote's suicide.
