Why? You could dance on1 real, on 2 real or on 3 real! This reminds me last year in Italy I was dancing with a lady from the DR and the first time I danced salsa with her felt pretty bad. Off time, CBL was not happening, steps all over the place...exactly what you would not expect from a DR latina. I then saw her dance bachata and I she was fantastic. I asked her again for salsa and I told her that she was a very good dancer. She told me she was just learning linear salsa and she was not very good at it. I told her to just do 123 on the spot and not to worry about lines and spins. Result? Fantastic! Followed everything I tossed at her! And with great body action! Yes there is such a thing as real salsa.
