death, something never to be recaptured went out of Haydn's life. A certain sarcasm in his nature began to show, an asperity of which the diary of his second trip to London offers many instances." A love affair? Geiringer and other biographers have addressed the question of whether Haydn was in love with Marianne. The most likely answer seems to be that he was, but was very aware of how catastrophic the consequences would be if they pursued a romantic connection, and exercised restraint. Moreover, the various veiled utterances found in Haydn's letters are not matched in Marianne's, who (Geiringer) "certainly showed no more than friendliness." Haydn biographer Rosemary Hughes writes: It is easy to see that he was, in a deeply respectful way, half in love with Marianne ... He anxiously assures her, when one of his letters to her had been lost on the way, that it contained nothing dishonourable for the inquisitive to seize on ... His deep anxiety was that she ... should take fright and break off their correspondence. Genzinger as dedicatee Haydn wrote his piano sonata in E flat, Hob. XVI/49 (1790), for Marianne. The work is considered one of Haydn's finest sonatas. Concerning the slow movement, Haydn wrote to Marianne, "I recommend it especially to your attention for it contains many things which I shall analyze for your grace when the time comes; it is rather difficult but full of feeling.". She wrote that "I like the Sonata very much, but there is one thing which I wish could be changed (if by so doing it does not detract from the beauty of the piece), and that is the passage in the second part of the Adagio, where the hands cross over; I am not used to this and thus found it hard to do, and so please let me know how this could be altered." The Abschiedslied Hob. XXVIa:F1 (Ende 1790) is also dedicated to her Notes References Hinson, Maurice (1992) Haydn: The Complete Piano Sonatas, Vol. 3, Alfred Publishing, Van Nuys, CA.
