A set of dance music, usually three to five songs, of the same dance in similar style, if not by the same orquesta. The tandas are separated by a brief interlude of non tango music called a cortina, during which couples select each other. It is customary to dance the entire tanda with the same partner unless the man is rude or very disappointing as a dance partner, in which case the lady may say gracias (thank you) and leave.
