(THE GREAT PIANIST, throwing back his head, strikes the massive opening chords of a Beethoven sonata. There is a sudden hush and each note is heard clearly. The tempo of the first movement, which begins after a grand pause, is allegro con brio, and the first subject is given out in a sparkling cascade of sound. But, despite the buoyancy of the music, there is an unmistakable undercurrent of melancholy in the playing. The audience doesn't fail to notice it.)
