“Yira yira” is a famous 1929 tango by Enrique Santos Discepolo. It is one of the most profoundly cynical tangos ever written and is regarded as a reflection of Argentina’s painful social reality in the 1930’s. It remains a classic to this day and its popularity goes beyond the genre of tango with modern pop and rock interpretations.
Though Discepolo says “Yira yira” was coming to him before 1929 and describes a feeling of hopelessness he experienced in various circumstances in his life, it’s at the beginning of the terrible decada infama of the 1930’s that he found the words to write it down. It’s also during that period that he felt it the most deeply. 
“Yira yira” is only a part of a series of related tangos in which Discepolo explores the topic of decadent social values from various points of view. Other socially engaged tangos by Discepolo include ” Que vachaché” (1928), “Que sapa senior?” (1931) and “Cambalache” (1934).
In “Yira yira”, Discepolo offers a rather pessimistic outlook on human nature. He warns us that there is no true love in this world and everything deep down is motivated by selfish interests. You can search and hope all your life but on the day you die, when your last hopes prove to be vain, you will have to admit true compassion is nowhere to be found.
When all the bells you ring die out, and you look in vain for a brother to die in embrace, then you will understand (remember) these words.
You’ll see that everything is a lie, you’ll see that nothing is love, and to the world nothing matters, it goes round and round.
The word “yira” is a lunfardo expression meaning “goes round”.
“Yira yira” was recorded by Carlos Gardel in 1930. It was also featured in one of his videoclips with a sketch where Discepolo presents the song to Gardel himself. It was prohibited under the military government in 1943 due to the use of lunfardo and for ideological reasons as well.
Other recordings of “Yira yira” include those of tango, folk and pop artists such as la Orquesta Típica Victor, Ada Falcon, Ignacio Corsini, Edmundo Rivero, Roberto Goyeneche, Hugo del Carril, Francisco Canaro, Javier Calamaro and Julio Iglesias.
