Learn the salsa change of place and enchufla: build-up, leading and following, spacing and typical mistakes, with honest notes on school and style.
The honest answer: in a change of place the leader and follower swap sides while the follower turns under the arm; in Cuban casino this basic figure is called "enchufla". It sounds like one movement but is really an interplay of path, timing and turn. If you learn it only as a "turn", you run into your partner.
Why is it worth it? Because the change of place is in many schools the first figure you really dance with others as a group, for example in rueda de casino where a whole circle swaps at once. In a study of ten dance couples the load in a rueda lesson was higher than in a "typical" salsa lesson, and on a club dance floor it was about as high as in the normal lesson [1]. So you are training your fitness too.
Realistic: the sequence works roughly after a few practice evenings. Clean timing and free swapping on a crowded dance floor take longer (experience, not a study result).
Mark the path on the floor with two markers (tape, shoes). The two starting points are on one line, at the end you have swapped points. Walk the path first without music and without hands. Who passes the other on which side? Your teacher defines this for your style; what counts here is the principle: you need a shared map.
Milestone: you swap places without touching and without colliding, in the time of one eight-count.
On the first counts (1-2-3) you dance the normal basic in open hold. On 4 the leader gives a small signal through the joined hand. The follower reads it and does not wait for a pull. A lab study (not dance, but linked arms) shows that people adjust their arm tension to the partner and the person with the more accurate information takes the lead [2]. For you that means: keep tension, do not go slack and do not clamp.
Milestone: you both recognise the moment when it "starts", without anybody pushing.
Standard practice without study evidence, schools differ in detail: on 5-6-7 you swap sides. The follower walks forward and turns under the raised arm; how much she turns is defined by the school. The leader steps aside, opens the path and turns along so that afterwards they face the partner again. On 8 you stand on the swapped places.
Milestone: both stand calmly on 8 and still have both hands free to continue leading.
After the swap you go straight back into the basic step. In rueda the swap is called by the caller (practice). Practise the exit as deliberately as the swap, because many beginners lose the beat here.
In leading and following, an experienced person attunes to the less experienced one: in a lab study with Greek folk dancers, the dance-experienced person led the inexperienced one at light hand contact (TRANSFER from folk dance, not salsa) [3]. So if you are the more experienced side, take your partner along. If you are the less experienced one, trust the signal.
On a crowded dance floor the most common danger is not the figure but a collision. Glance in the direction of travel before the swap, keep the figure small and cancel if in doubt. Practical note without study evidence: never close your hand tightly around the partner's wrist; the follower should be able to let go at any time.
The arm is led briefly during the turn: never pull it up beyond a comfortable range or hold it, stop immediately if you feel pain in the shoulder or wrist. This guide explains the principle and motivates. It does not replace supervised training: have the path and the arm shown by a teacher.
Dance the change of place once completely without hands, only with eye contact and body language. If that works, you can reduce the hand connection afterwards to what it should be: a quiet signal and not a steering wheel.
A figure where both partners swap places and the follower turns under the arm. The exact footwork and turn differ by school, so your teacher's sequence applies.
Enchufla is the Cuban name for this basic figure in casino style and a typical call in rueda de casino, where a whole circle moves at the same time. Your class leader tells you which variation is meant.
In a study of ten dance couples the heart-rate load in the rueda lesson was higher than in the typical salsa lesson [1], and in the club it was similar to the normal lesson. For beginners this is not a warning, just a hint to include breaks.
Glance in the direction of travel before every figure, keep it small when it is crowded and agree who leads. Practical experience: anyone who has not practised the figure once without hands is more likely to be insecure on a crowded floor.
