Furiant
A Furiant is a rapid and fiery Bohemian dance in alternating 2/4 and 3/4 time, with frequently shifting accents; or, in "art music", in 3/4 time "with strong accents forming pairs of beats".
The stylised form of the dance was often used by Czech composers such as Antonín Dvořák in the eighth dance from his Slavonic Dances and in his 6th Symphony, and by Bedřich Smetana in The Bartered Bride and in Czech Dances. The use of the furiant by central European composers closely parallels their use of the Dumka (dumky), a dance which often precedes the furiant.
