Argentine Tango
Fascinating, sensual passionated and emotional. What a better way to describe Argentine tango. Having its origins in the suburbs of Buenos Aires and in Montevideo of Uruguay at the end of the 19th century. Started as a mournful dance between men and it now is a diverse mixture of African slave music and classic European music including polka, opera, waltz and folk songs. In the dawn of 20th century it quickly spread internationally, as a result of its great popularity. Argentine tango has many styles that developed in different regions and eras. With time signatures varying from 2/4, 3/4 and 4/4 for different rhythmic interpretations. 
Argentine tango's basic element is feeling the music and translating that through dancing with a partner, while maintining a correct leading. This is very important when learning to dance, since Argentine tango is relying on a great amount on improvisation. (Even though there are basic steps and standarized figures). The follower has rarely their weight on both feet at the same time, thus to be able to follow the leader, the first has to be able to feel the music and have deeper understanding and connect with each other.
It is danced in an embrace which can be either very open where the leader and follower connect at arm's length, or a very closed one.
Some of Argentine's popular styles are :    - Tango Nuevo (Open embrace with the man's hand embracing only the woman's left side and by the lifting of the feet)   - Milonguero (A simple approach to Tango focusing on the walk, cadence, and communication between partners)    - Salon (smooth and elegant with more variety of movements and figures in comparison to the other styles)   - Show tango (Choreographed Tango with elements of Salon, Orrillero, Tango Nuevo, as well as Ballet and Modern Dance).
