Curators at the Morgan Library & Museum in New York City have discovered a music manuscript believed to be by Frédéric Chopin, the first new work by the composer to be found since the 1930s. The sheet music, measuring 4-to-5 inches, is believed to have been originally intended as a gift. Chopin experts have called the discovery a significant find in the world of classical piano music. The piece, which lasts about one minute, expands our understanding of Chopin as a composer and raises new questions for scholars to consider.
