The Argentine waltz is also called vals criollo or vals Cruzado. The vals has its origins in the European waltz. He is danced throughout South America and has got his own little spicier, color there. The waltz also has its own, special moves, but the basic steps, like at the milonga, are similar to those of the tango. The moves are somewhat less exuberant and more like what one would apply in the waltz at ballroom dancing. There are many twist moves (gyros) danced in both directions.

The attitude and the basic figures are for Tango Waltz the same as in regular tango.

Tango Waltz music obviously has a three-quarter measure.

The music is a little faster and a little more cheerful. Romantic music fits well with this form of the tango.
