A two-step consists of two steps in approximately the same direction onto the same foot, separated by a joining or uniting step with the other foot.
[2] "The Texas Shuffle step was formerly called a foxtrot step and has erroneously been called Texas Two-Step.
"[3] "There are really two histories of what is called 'two step dance,' because the name jumped from one type of dance that is no longer done to another that is done, called the Texas Two-step or collegiate Fox-trot.
The original Two-step was a simple dance that first caught on with the public when John Philip Sousa came out with the 'Washington Post March' in 1889."
In Europe the two-step became popular from around 1900 until the 1910s, when the one-step and the foxtrot took over.
