In the spring of 1865, Brahms surprised his acquaintances with 16 small waltzes for piano with four hands. He wrote about it in a letter written in April 1866 to his friend and famous critic Eduard Hanslick, saying "to have thought of Vienna and the pretty girls". And that's how they also sound - light, twirling, you could almost say Schubertian. To date, they have enjoyed great popularity, including as domestic music. Brahms adapted them himself in a version for piano with two hands (HN 42, 43).
