Here's a short story:

The piano on which Mozart wrote all of his late works returned home to Vienna for the first time since his death in 1791.The piano will stand in his former Vienna home, now a museum, for two weeks, ending in a concert of the works by Mozart. Mozart bought the instrument from Anton Walter, the most famous piano maker of his time, in 1782.He wrote more than 50 works for the piano on it, many of them in the apartment in Vienna.After Mozart's death, Constanze, Mozart's wife, gave the instrument to their elder surviving son, Carl Thomas, who donated it to the Mozarteum Salzburg on what would have been the composer's 100th birthday.The piano is now part of the permanent exhibition in the Austrian city of Salzburg. " It was very hard to let it go," said Matthias Schulz, director of the Mozarteum Salzburg." If we didn' t know it was in the best hands, we wouldn' t have done it." The piano is much smaller and lighter than modern concert ones.Its sound is fresher and brighter than that of a modern piano, with lighter action and hammers . Piano restorer Josef Meingast, who has looked after the Mozart piano since 1975, said it was superior to any of its surviving copies.Meingast said he had to fight to replace the existing strings , dating from a 1973 restoration, with softer ones that produce a rounder sound thought to be more similar to what Mozart would have produced. Russian pianist Alexander Melnikov, who planned to give a concert of Mozart' s music on the piano on November 7, said he was privileged to play such an instrument.It's easily the biggest day of a musician' s life."
