I am wondering if anyone knows something specific about the dates of
composition of the Etudes op.125. Somewhere I read that Hummel played
some of them for someone else about 1828 and he apparently composed
six in 1833 to complete the set for publication. The notes to Boehm's
recording seem to suggest that these six are the ones omitted from the
Universal edition (g, a, B, c-sharp, E-flat, f), which is odd, because
it suggests that Universal would have used a manuscript from before
the summer of 1833 as a source and not the first editions of that year
or later reprints. Also, Sachs was unable to include the Etude in B-
flat submitted to Fetis for inclusion in Methode des methodes. Does
this mean that he could not locate a copy, or that the owner would not
cooperate in the complete edition? It seems to me that this etude may
be the one in that key from op.125.
