Buenos Aires Carnival in Buenos Aires
Buenos Aires's carnival plays out as dozens of neighborhood corsos barriales rather than one central parade, with murga troupes marked by a cymbal-topped bass drum and a bouncing dance step performing satirical songs in barrios like Mataderos, La Boca and Boedo across several weekends, free and open to whoever wants to follow a group from block to block.
A single bass drum rigged with a cymbal, the bombo con platillo, is the instrument that identifies a Buenos Aires murga from a block away, and it is also the clearest evidence of the porteno carnival's borrowed origins.
