Three steps don't make triple time
The three-step is called Three Step in English. Its name describes the number of steps, not the time signature: Slow Foxtrot is danced in 4/4 time. A Slow lasts two beats, and each Quick lasts one. For your first practice on your own, you can count “one, two, three, four”: The first step begins on one, the second on three, and the third on four. You don't take an additional step on two.
The role labels here describe the direction of movement. In the usual version, the leader moves forward and the follower moves backward. You can first learn both foot patterns on your own, regardless of which role you'll take when dancing with a partner. Straight ahead means without turning, not placing one foot directly in front of the other along a single line. Your feet move along two narrow, natural tracks.
When dancing with a partner, the three-step stays within the closed position: Neither person steps sideways to pass the other. You can find a more detailed overview of the three dances in the introduction to Foxtrot, Slow Foxtrot, and Quickstep. If you already know a social Foxtrot basic step, don't automatically use its foot pattern here: the steps in Foxtrot are a separate part of learning. Here, you'll practice just one three-step, with a deliberate ending.
