Courante
The courante was a fast, running dance with 3 beats in a bar (the time signature was often 3/2, although sometimes it was 3/4).  During the 17th century the French courante started to become slower than the Italian corrente, and it often had more counterpoint (imitating parts).  However, this was not a strict rule, and the courantes that Bach wrote were both Italian and French in style, and sometimes he called them "courante" and sometimes "corrente".
