Foxtrot
At its inception, the Foxtrot was originally danced to ragtime. Today, the dance is customarily accompanied by the same big band music to which swing is also danced. From the late teens through the 1940s, the Foxtrot was certainly the most popular fast dance and the vast majority of records issued during these years were foxtrots. The waltz and tango, while popular, never overtook the Foxtrot. (Even the popularity of the lindy hop in the 1940s didn't dent the Foxtrot because the Foxtrot could be danced to those lindy hop records, as well.)
