A recent discovery in the vault of the Morgan Library and Museum has unveiled a waltz believed to be penned by Frédéric Chopin between 1830 and 1835. Curator Robinson McClellan located the manuscript, which bears similarities to Chopin's distinctive handwriting and bass clef symbol. After consultation with a Chopin expert, the piece was authenticated, suggesting it might be one of the few lost works of the composer known for his piano solos. Esteemed pianist Lang Lang describes the piece as beautifully capturing Chopin's style with its dramatic melody.
