In Buenos Aires, tango is a social code before it is a stage show. Lower your voice, do not cut across the floor edge, and skip flash photography. Invitations often use cabeceo—eye contact and a slight nod—not shouting across tables.
Shoes should grip lightly and feel comfortable. On night one, listen to musical phrases instead of forcing advanced figures. After a tanda, thank your partner and return to your seat; no one “owns” a partner.
San Telmo and Villa Urquiza carry different energies. A show is lovely, but real tango conversation begins at milonga tables.
