Beethoven initially intended to compose all three sonatas consecutively, and when he had finished the first he told the publisher that he was now working on the other two "without delay". Several elements are combined to form the composite finale, starting with a vocal-style recitative, followed by a ‘lamenting song’ (recalling the previous sonata’s ‘song’). This gives way to a fugue that gradually builds up to an impressive climax, only to subside to an even more anguished version of the lament, marked ‘exhausted, lamenting’. The fugue then returns, initially with the theme inverted (descending instead of ascending), and marked ‘little by little reviving again’. The music does gradually revive, eventually building up to an even grander climax than before, leading to a triumphant conclusion.
