Composers such as Beethoven and Schubert wrote waltzes, but these pieces were the equivalent of modern dance music. They were functional and meant to be danced to. Carl Maria von Weber's Invitation To The Dance written for piano was the first instance of a waltz written to be listened to instead of danced to. Chopin helped refine the concert waltz and his first attempts in the form used Weber's as a model.
Chopin wrote at least 36 waltzes, but only 18 verified waltzes still exist. The others are either destroyed, held by private owners while the fate of others is unknown. Chopin had only eight waltzes published during his lifetime, and on his death bed he instructed his publisher to destroy all of his unpublished works, but this was not done. Five waltzes were published shortly after his death and another five later. The two waltzes of Opus 69 were published in 1854, 5 years after his death.

No. 2 In B Minor - This waltz was written in 1829 before Chopin left Poland. The main theme is in B minor that is more melancholy and restless than the previous waltz, partially on account of the chromaticism of the main theme. Once again Chopin mixes major and minor (or in this instance minor with major) as the first episode after the statement of the theme changes to B major, but the overall feeling doesn't change. This piece is one of the least technically demanding waltzes, but that's no reason to dismiss it. Chopin was above everything else, a master of the piano miniature, with this waltz being a good example of his skill and artistry.
