An interesting bit of trivia about Irving Berlin:
While not known as a virtuoso
, many considered Irving Berlin to be a fine pianist
and he had several performances during his career, both informal and at Hollywood
It was a well-kept secret among his family, friends, and close associates that he could only play in one key
: F# Major
. Everything he compose
d was in F# as he wrote at the keyboard
and then had be transposed
in to an appropriate key.
I found this to be quite amusing.
