The London dance instructor Pierre Lavelle, who was responsible for having the Cuban Rumba declared the official Rumba, while on a visit to Cuba, had noticed that sometimes there were extra beats added to the Rumba. Upon his return to England he taught these steps as a completely new dance. It has been suggested that the name Cha-Cha (or Cha-Cha-Cha as it is called by some people) was coined for the sound of the 3 quick steps after the forward and back step (or back and forward steps). The steps for the Cha-Cha are taken on the beats accompanied by a strong hip movement as the leg straightens on the half beat.
The Cha-Cha is a fun, flirty, lighthearted dance that gets its distinctive "cha, cha, cha" rhythm because there are 5 steps danced to four beats. Dancers work parallel with each other in well synchronized movements sometimes employing the "New Yorker", a step where one of the dancers steps across the other and checks to change direction. Cuban motion, the hip motion derived from alternately bending and straightening the knees, is an important factor in this dance.
