You may not realize this but you have an accent. The place that you live in, the people that you dance with, the teachers that you have studied with, and last but not least, the variation of those ideas from the original, creates a local tango ‘accent’. Every city where Tango is danced has an accent which is specific to that place and to that place alone. Boston, San Francisco, Paris, London, Berlin, Moscow, etc. They all have one, up to and including Buenos Aires, especially Buenos Aires! The difference between your local flavor of Tango and say Boston, Paris, and London, is like night and day within a spectrum of ideas.
