Hi!

I'm new to this group, so I'm not sure if a similar question has been
asked already, sorry...

I'm looking for sources to come as close as possible to an authentic
text of Hummel's magnificent piano sonata in F-sharp minor op. 81.

The thematic catalogue doesn't list a manuscript. Is it lost? Any
story behind that?

There is a quasi-facsimile reprint of the first edition done by Joel
Sachs. Is this the only source that later editions referred to? The
Dover, for example, is a reprint of a Charles Berio edition (same as
Universal?), heavily altered with all kinds of written in rubatos,
and many of the free figurations in the second movement are metered.
Did Hummel have anything to do with any of these alterations?

I'd be immensely grateful for any hints!!!

Great to see that such a group exists.
