"Milonga is an excited habanera." The original habanera divided into four pulses, in a standard two-four where every note was stressed. In becoming milonga, though, all four notes turned strong, as tempo was doubled. The strength of the first beat weakened the fourth giving an almost waltz-like feel to milonga: one-two-three (four), one-two-three (four). Habanera is a slower, more explicit sounding one, two, three-four. At least one modern tango pianist believes the polka influenced the speeding up of the milonga.
Milonga has a syncopated beat, consisting of 8 beats with accents on the 1st (sometimes also 2nd), 4th, 5th, and 7th beats.

In Rio Grande do Sul, milonga is an important regional genre and it is part of the repertoire of many gaucho musical groups and interpreters. It also continues to influence other genres of the modern gaucho music. José Cláudio Machado's "Milonga Abaixo de Mau Tempo", Renato Borghetti's "Milonga para as Missões" and Jayme Caetano Braun's "Bochincho" are examples of the traditional rio-grandense form of milonga, while Vitor Ramil's "Ramilonga" and Bebeto Alves's "Milonga Orientao" are examples of modern form of this genre.
Argentine composer and pianist Fernando Otero has based many of his orchestral and chamber works on this rhythm,  creating compositions for Symphonic Orchestra, String Quartet and Jazz Combos.
