Nope, you heard right. The tango that for most people defines the genre, the dance, the music, the rhythm and everything else about tango, was composed as a little march for marching band – in Uruguay. That’s right, Gerardo Matos Rodriguez, the composer of La Cumparsita (that’s a march, not a tango) wasn’t from Argentina either.
They know far more about tango than I do, so read all about La Cumparsita on Todotango
