The original format ( from 1978/9 ) DOES have a tap. The dance commences with an in place on 1 ! followed by ( in place ) tap on 2, hence its name, 2 being the break step in Mambo and Cha, and the syncopation that follows ( 3 and 4) is the timing of Guajira .
it is also danced more laterally than slot style .
