Nothing but His Songs - ‘Irving Berlin’s White Christmas’ at the Marquis Theater

NYTimes.com: "IF you didn’t know better, had never been taught the proper technique, you might approach a piano with your hands flat and fingers splayed, as if instead of striking the keys you were going to dribble them. This may be why Irving Berlin, who never studied music except with his ear, favored the ebonies over the ivories when he first started playing. His melodies found their home among the black keys, making excursions as necessary to the white, with the result that the tunes all emerged in the absurd six-sharp thicket of F-sharp major or its corresponding D-sharp minor."
