Waltz in A minor (Chopin)

Frédéric Chopin's Waltz No. 19 in A minor, B. 150, KK IVb/11, P. 2/11, is a waltz for solo piano. The waltz was written sometime between 1843 and 1848, but was not published until 1860, after the composer's death, by Jacques Maho. At this time, it was attributed to Charlotte de Rothschild and was published as No. 3 of "Four pieces for piano". This collection also included Chopin's Nocturne in C minor, B. 108. It was not until 1955, 95 years after its initial publishing, that it was correctly attributed to Chopin.
Structure.
This waltz is structured as a single movement in rondo form marked allegretto. It is one of Chopin's shortest, least ambitious, and technically easiest waltzes.
Analysis.
The piece shows great sadness, while enclosing some episodes that hint at happiness and hope. The first theme of the piece uses a simple but effective melody, conveying a sad portrait, with decorative ornaments used throughout. The second theme is more interesting and lively, punctuated by a brisk ascending arpeggio, although it still has a certain sadness. About halfway through the piece, there is a modulation into A major, featuring a happy and joyful melody. The piece concludes with the main theme, followed by a short coda.
