For the first time in more than 90 years, a new piece of music believed to be by the Polish composer Frederic Chopin has been discovered nearly 200 years after it was written. The unknown waltz was unearthed in the vault of the Morgan Library and Museum in New York.
The manuscript, dated between 1830 and 1835, was discovered by curator Robinson McClellan while cataloguing new collections.
Daniel Vnukowski explores the new discovery and questions whether the work is really by Chopin.
