The Hungarian Dances (German: Ungarische Tänze) by Johannes Brahms (WoO 1), are a set of 21 lively dance tunes based mostly on Hungarian themes, completed in 1869.
They vary from about a minute to four minutes in length. They are among Brahms' most popular works, and were certainly the most profitable for him. Each dance has been arranged for a wide variety of instruments and ensembles. Brahms originally wrote the version for piano four-hands and later arranged the first 10 dances for solo piano.
Only numbers 11, 14 and 16 are entirely original compositions. The most famous Hungarian Dance is No. 5 in F♯ minor (G minor in the orchestral version), but even this dance was based on the csárdás by Kéler Béla titled "Bártfai emlék" which Brahms mistakenly thought was a traditional folksong.[
