Argentine tango music is much more varied than ballroom tango music. A large amount of tango music has been composed by a variety of different orchestras over the last century. Not only is there a large volume of music, there is a breadth of stylistic differences between these orchestras as well, which makes it easier for Argentine tango dancers to spend the whole night dancing only Argentine tango. The four representative schools of the Argentine tango music are: Di Sarli, D’Arienzo, Troilo and Pugliese. They are dance orchestras, playing music for dancing. When the spirit of the music is characterized by counterpoint marking, clarity in the articulation is needed. It has a clear, repetitive pulse or beat, a strong tango-rhythm which is based on the 2x4, 2 strong beats on 4 (dos por cuatro). Astor Piazzolla stretched the classical harmony and counterpoint and moved the tango from the dance floor to the concert stage. His compositions tell us something of our contemporary life and dancing it relates much to modern dance.
