Two-step (Two Step) is the name of several dances, some related to each other and some not. When the context doesn't indicate a particular Two-step, the more complete name is generally used. Modern dances under this name include:
Other dances with this name were danced in the 19th century in the USA under the music of John Philip Sousa marches (Washington Post Two Step), which was kind of slowed-down, but jumpy Polka or Galop, as well as in the beginning of the 20th century in Europe and USA.
It also describes a subgenre of electronic dance music developed in the 1990s and which has become prominent in 2001.

The slow twostep is a Latin dance, a round dance rhythm danced to slow, romantic music with either 4 or 6 beats per measure and a tempo of 16–32 measures per minute.
The nightclub twostep or California twostep was originated by Buddy Schwimmer, Lee and Linda Wakefield, and Ron Montez in the mid 1960s in crowded dance clubs on the West Coast as a dance that could be used for very slow love ballads that are otherwise difficult to dance to.
Slow twostep was introduced to round dancing in the early 1990s by Bill and Carol Goss, but they presented it as a "slow, quick, quick" rhythm, with the side step done first and the rock/recover second.
