The Structure of Argentine Tango
Despite its seemingly infinite variety of figures, Argentine tango has a clear, underlying structure, from which all figures can be derived. Only four variables are required to explain the diversity of tango figures: step type, step direction, step style, and intrusion mode. Understanding the role played by these variables and the rich interplay amongst them can help dancers avoid memorizing a large number of overlapping step sequences, and instead improvise figures based on the possibilities offered by the fundamental structure at any moment in the dance. With the stress from memorizing sequences removed, the door opens to enjoying the dance in its comprehensibility and simplicity.
