As for the length of fingers, it is a well-known fact
that amongst the famous pianists of the past a roughly equal number
belonged to the long-finger and the short-finger group respectively.
Busoni, Rachmaninov, Rosenthal, Sauer had long fingers;
d'Albert, Reisenauer, Teresa Carreño, Pachmann and others had short ones.
The inevitable period of uncreative stagnation which followed
the exuberance of the Lisztian proliferation era,
was none the less remarkably fertile with fine pianists,
some of them pupils of Liszt.
Artists like Rosenthal, Pachmann, Emil von Sauer, Eugen d'Albert
and many others inundated European and American concert platforms.
