The piano sonata was still a relatively new form when Beethoven published his first set in 1795. In the next twenty-seven years, the composer would revolutionalize the way composers wrote for the instrument, placing ever greater technical demands not just on the stamina of performers and audiences but on the instruments that were used to play them. Today's piano, the modern concert Steinway favored at Carnegie Hall is an engine of steel, not the wooden box that Beethoven and Liszt were forced to contend with and sometimes break with the ferocity of their attack.
