NEW YORK (AP) — A previously unknown musical work written by composer Frederic Chopin appears to have been found in a library in New York City. The Morgan Library & Museum says the untitled and unsigned piece is the first new manuscript of the Romantic era virtuoso to be discovered in nearly a century. Robinson McClellan, the museum’s curator, says he stumbled across the work in May while going through a collection brought to the Manhattan museum years earlier. He worked with outside experts to verify the document’s authenticity. But there’s debate whether the waltz is an original Chopin work or merely one written in his hand.
