Often called the ,Texas two-step, the 2-step is a country western dance normally danced to country music.
As with other Country/Western dances, there are different versions of 2-step. Even the same dance may go by different names depending on the area of the U.S., sometimes even in a particular dance hall.
Basic 2-step consists of two quick steps, followed by two slow steps or, alternately, two slow steps followed by two quick steps; the dancing may start with either the slow steps or the quick steps depending on preference. More advanced figures can be syncopated.
Formally, the quick steps are full strides, with one foot passing the other on each step. However, in informal situations, particularly when the beat of the music is fast, the second quick step may be a shuffle with the foot that's behind, following the first quick step, sliding up to, but not even with, the foot in front. This often referred to as 3-Step.
This style has roots in Foxtrot. Basic 2-step patterns are equivalent to those of many other progressive partner dances.
