Tango Códigos - what are they?
So, the Tango "Códigos" or codes (of conduct) are the basic etiquette of Argentine tango. The códigos themselves are all about respecting your dance partners, the other dancers, and the organizers at an Argentine tango event.
Tango códigos are much more than just asking for a dance. Tango culture developed códigos to make the dance experience safe and enjoyable -- safe from those who might injure others on the dance floor, from those who demand dances or pester others. Knowing and using the Códigos means that you understand that dancing tango is a community activity and you choose not to spoil the experience for yourself or other dancers. Adhering to them means more fun dancing for everyone.
