The move is in no way among the most difficult Setenta moves but it received the qualifier complicado simply to distinguish it from the standard Setenta version. While the first 8-count of this move is identical to the standard Setenta move, leaders bring their left hand over their head on beat 7. What makes this move more difficult than the standard version is that for the second 8-count leaders lead the Enchufla behind their back (before they do a Ronde Moderno) which is a very common element found in many other moves but dancers usually experience this element for the first time when learning Setenta Complicado.
In order to execute the Enchufla behind your back, an easy way to get used to this initially is for leaders to try and look at their follower by turning their head towards their left hand side which will automatically puts them into the correct position. It does feel slightly more natural initially for leaders to look at their follower by turning their head to their right, however, this will make it impossible for them to complete this move and it is one of the most common issues new dancers have when trying this out.
Like most other Setenta variations the ending is a simple Enchufla, which can be embellished by Alardes, Ganchos, Styling etc. As usual at Tiempo España Dance Academy we finish Setenta Complicado with an Enchufla Ronde which can of course be changed when social dancing but it keeps things consistent when performing Setenta Complicado in a Rueda.
The hand sign for this move is the hand sign for Setenta followed by the sign for Complicado which involves the caller forming a fist with their free hand and knocking it against their head. It is irrelevant how many times the fist is knocked against the head, it is simply meant to convey that it hurts your brain to figure out this move i.e. because it is complicated.
Other hand signs are also sometimes observed for this such as making a circling motion next to your head with your index finger. However, this sign is also used for the modifier “loco” which is used to describe a different set of moves so we use the former sign at Tiempo España Dance Academy to avoid ambiguity.
