Ok, get ready for some of the best damn music ever!

Johannes Brahms was one of the most most popular composers in history. He may be best known today for his famous Lullaby, but he also wrote a number of short tunes, his era's "pop music": his waltzes and his Hungarian dances. The Hungarian dances were based on traditional folk music; only a couple were fully original compositions. Initially most were written for piano, the rest were transcribed for orchestra by others including Antonin Dvorak.

The Hungarian dances by Brahms inspired Antonin Dvorak to write a similar set of pieces, his Slavonic dances. He also wrote them for piano but his publisher promptly requested that he write orchestral arrangements.
