Why Do We Still Dance to These Old Tango Songs?
It is no accident that the mood of an entire tanda is the same even to the point of having the same orchestra from the same year with the same sound and rhythms to the songs (for instance Rodolfo Biagi used to play piano for Anibal Troilo, when Biagi formed his own orchestra the sound of Troilos music changed radically, so you wouldnt want to mix songs with and without Biagis famous rhythms in a Troilo tanda because it would disrupt the flow and connection developed by the milonguero) tango is a complicated dance and there are nights and partners where it takes all 4 similar songs to create a good connection a milonguero depends on this structure to create confidence in his partner.
