The allemande is believed to be of German origin. Sometimes called almain it was originally in duple meter with a moderate tempo but evolved to a quadruple meter with a faster tempo. It is very often used as the first dance in the Baroque suite sometimes preceded by a prelude.
Allemande from French Suite No. 2 in C minor BWV 813 by J. S. Bach (binary form):
