Chopin: Waltz in A minor (Newly discovered in 2024)

A few weeks ago, the classical music world was treated to big surprise when it was announced an unknown waltz by Frédéric Chopin (1810 - 1849) has been discovered in a library in New York.
According to the New York Times, Robinson McClellan was sorting through a collection of cultural memorabilia in the vault of the Morgan Library and Museum in Manhattan when he found a pockmarked manuscript the size of an index card with a distinctive name written on the top right corner: Chopin.
He shared a photo of his discovery with Jeffrey Kallberg, a leading Chopin scholar at the University of Pennsylvania. After a thorough analysis of the paper, ink, handwriting and musical style, the Morgan Museum has concluded that the work is indeed an unknown waltz by the great Polish composer. The momentous discovery is the first of its kind in more than half a century.
The manuscript is dated between 1830 and 1835, when Chopin was in his early 20s, and the music differs in many ways from the composer’s usual style. Though believed to be complete, the work is way shorter than Chopin’s other waltzes - only 24 bars long with a repeat. The piece, in the key of A minor, has unusual dynamic markings, including a triple forte, signifying maximum volume, near the start.
Comparing with the other more technically challenging Chopin pieces, this one is relatively easy, and I learnt the whole piece within a day.
I can’t believe Chopin just dropped a new single in 2024, 175 years after his death!
