Performances take place in the form of parades (known as corsos) across the various neighbourhoods of Buenos Aires; some groups feature not only dancers and musicians but also jugglers, stilts, flagbearers, and other types of visually stimulating elements.
In the period preceding Carnival, which takes place from late January to early March in Uruguay, each group will prepare a musical play consisting of a suite of songs and recitative (heightened speech) lasting around 45 minutes.
Lyrical content is based on a particular theme, chosen by the group, which serves to provide commentary on events in Uruguay or elsewhere over the preceding year.
For example, during the dictatorship in Uruguay in the 1970s, groups like Araca La Cana [es] became known for their left-wing tendencies, subversive commentary and oppositional stance.
These get played on the radio during the Carnival period and some of them, such as the Saludo Araca La Cana 1937, are cherished by Uruguayans as cultural icons.
Examples of artists who have included murga in their arrangements are Jaime Roos, Rubén Rada, No Te Va Gustar, Máximo Diego Pujol Washington Luna [es], and Alejandro Balbis.
