Often referred to as the 'dance of love' the name rumba actually means 'party' and it's likely that it developed into a sensual dance through the influence of choreographers and slower tempo music. It shares many figures with the cha-cha-chá but without its signature chassé. In the real world, couples can use the rumba in small dance spaces to slower tempo songs. Something like 'Sexual Healing' by Marvin Gaye!
