There are three kinds of Argentine tango: tango salon, milonga, and tango vals. They are written in 4/4, 2/4, and 3/4 time, respectively.
Tango valses tend to have a romantic feel and vals tandas (sets of 3-5 related works) often are played toward the later part of the night to encourage newly-met couples to exchange contact info.
Tango valses are fast tempo, so dancers typically only step on one beat of each measure. Usually but not always this is the first of the One-two-three beats. But for variety dancers may throw in double- or triple-step sequences.
One of the most popular is “Desde el Alma” (dez-del-ol-ma, “Out of the soul” or “From the soul”). It was composed by 14-year-old FEMALE musical prodigy Rosita Melo in 1911. The words were much later written by her husband, then the more famous version by Homero Manzi.
The Rose Pavilion was a large two-story chalet style cabaret and ballroom surrounded by a garden. Tango greats played their music and danced there during its lifetime from the late 1800s to 1929. (Other non-tango events were also held there.)
“Heart of gold” was written by composer, orchestra leader, and impresario Francisco Canaro.
“Tears and Smiles” was composed by Pascual de Gullo & N. Casuscelli.
“Blue Illusion” was composed by Alfredo De Angelis.
