Tango

Tango is the urban music of the Río de la Plata — the river estuary shared by Buenos Aires and Montevideo — born in the port neighbourhoods of the late 19th century and built around the wheezing, pleading sound of the bandoneón. It is a music in 2/4 or 4/4 with a marked, walking pulse, sharp accents and dramatic pauses, written for a dance of close embrace and for songs about loss, nostalgia and the city itself.

This guide covers where tango came from, how the orchestras of its Golden Age were built, what the rhythm actually does, the three dance forms of tango, milonga and vals, the singers and bandleaders to start with, and how Astor Piazzolla and later electrotango changed it. Tango is not the same thing as the ballroom tango of dance competitions, nor the tangos palo of flamenco — both are explained below.

Tango is a genre of song and dance music from Argentina and Uruguay. At its centre is the orquesta típica: a section of bandoneóns (a square button accordion of German origin), a section of violins, piano and double bass. The music is mostly in a minor key, harmonically rooted in European art music and Italian song, and rhythmically descended from the habanera, the Creole milonga and the Afro-Rioplatense candombe.

What makes tango recognisable is its combination of rhythmic bite and lyrical melancholy. The accompaniment marks the beat with heavy, detached chords — the marcato — while violins or a singer spin long legato lines over the top. Phrases often end abruptly on a sharp cadence, and arrangements alternate between staccato drive and slow, stretched passages. Nothing in tango is supposed to sound casual.

The word covers several related things that are easy to confuse:

• Argentine (Rioplatense) tango — the music this guide is about, and the social dance danced to it in milongas (dance halls) worldwide.
• Ballroom tango — a standardised competition dance developed in Europe from the 1920s onward, with its own staccato style and a repertoire that is often not Argentine at all.
• Flamenco tangos — a palo (form) of Spanish flamenco in a binary rhythm; it shares the name and some Atlantic ancestry but is a separate tradition.
• Finnish tango — a popular national adaptation, slower and more song-like, with its own festival in Seinäjoki.

Tango emerged in the 1880s and 1890s in the arrabales (outskirts) and port districts of Buenos Aires and Montevideo, at a time when both cities were absorbing huge numbers of European immigrants, mainly from Italy and Spain. Its ingredients came from everywhere in the region: the Cuban habanera rhythm, the rural Argentine milonga sung by payadores, the drumming and dance steps of Afro-Argentine and Afro-Uruguayan candombe, and the polkas, mazurkas and opera arias the immigrants brought with them.

La Guardia Vieja (the Old Guard), c. 1895–1920. Early tango was played by small, mobile trios of flute, violin and guitar, and the bandoneón arrived as the instrument that would define it. Ángel Villoldo's "El choclo" (1903) is one of the best-known early compositions. Around 1912–1913 tango became a fashionable craze in Paris, and the European approval made it respectable back home. In 1917 Gerardo Matos Rodríguez's "La cumparsita", written in Montevideo, began its career as perhaps the most famous tango ever written.

The tango-canción. In 1917 Carlos Gardel recorded "Mi noche triste", with lyrics by Pascual Contursi — usually cited as the first tango-song, where the lyric tells a personal story instead of serving as dance filler. Gardel became the voice of tango, starred in films and recorded "Volver" and "Por una cabeza" with lyricist Alfredo Le Pera before his death in a plane crash in Medellín, Colombia, in 1935.

La Guardia Nueva, 1920s. Bandleaders such as Julio De Caro and Osvaldo Fresedo refined the ensemble, gave more room to arrangement and counterpoint, and settled the sextet into the core of the orquesta típica.

The Golden Age (Época de Oro), c. 1935–1955. Tango became mass music. Big orquestas típicas played in dance halls, clubs and on the radio, and the recordings from these two decades are still the main repertoire of social tango today. Juan D'Arienzo revived dancers' interest from 1935 with an emphatic, rhythmic style; Carlos Di Sarli, Aníbal Troilo, Osvaldo Pugliese, Francisco Canaro, Ricardo Tanturi, Miguel Caló, Alfredo De Angelis and Rodolfo Biagi each built a distinctive sound. Poets such as Enrique Santos Discépolo ("Cambalache") and Homero Manzi ("Sur", with Troilo) gave the lyrics literary weight, often in lunfardo, the street slang of Buenos Aires.

Decline and reinvention. From the late 1950s, rock and roll, changing tastes and political upheaval in Argentina shrank the dance halls. Astor Piazzolla pushed tango toward the concert hall (see below), and the stage show Tango Argentino, which opened in Paris in 1983 and reached Broadway in 1985, sparked a worldwide revival of the dance. In 2009 UNESCO inscribed tango, nominated jointly by Argentina and Uruguay, on its Representative List of the Intangible Cultural Heritage of Humanity.

Tango is written in 2/4 or 4/4 and organised in four-bar and eight-bar phrases that dancers feel physically. Its key musical traits:

• Marcato: the basic accompaniment — heavy, detached chords on every beat (marcato en cuatro) or on beats one and three (marcato en dos), played by piano, bass and bandoneóns together.
• Síncopa: a syncopated accent that anticipates the beat, giving tango its forward lurch.
• The 3-3-2 pattern: an eight-pulse grouping inherited from the habanera and milonga, used especially in milonga and later by Piazzolla as a driving ostinato.
• Arrastre: a dragged approach into the downbeat, a hallmark of Pugliese's orchestra.
• Yumba: Pugliese's heavy, almost percussive marcato, named after his 1946 composition "La yumba".
• Harmony and melody: mostly minor keys, with chromatic lines, strong dominant chords and frequent passages where violins and bandoneóns trade the melody.
• Extended techniques: violinists play chicharra (a scratching sound behind the bridge) and látigo (a whip-like glissando); bassists slap the strings; bandoneóns hit percussive chords.

There is no single tango BPM — recordings range from slow, almost rubato songs to brisk dance numbers, and orchestras differ sharply. The three dance forms, though, have clear identities:

The tango ensemble grew from a street trio into one of the most characteristic orchestras in popular music:

• Bandoneón — a bisonoric button concertina developed in Germany in the mid-19th century and associated with Heinrich Band, whose name it carries. Each button can sound a different note on push and pull, which makes it notoriously hard to master. In tango it supplies both melody and percussive rhythm.
• Violin — carries the long melodic lines and countermelodies; Golden Age orchestras used a section of four or more.
• Piano — the rhythmic engine, playing the marcato and fills between phrases.
• Double bass — anchors the beat and adds slaps and accents.
• Guitar — the accompanying instrument for singers outside the orchestra (Gardel was usually backed by guitars) and, electrified, a core voice in Piazzolla's quintet.
• Voice — the cantor de orquesta sang one or two refrains within a dance arrangement; the solo tango singer dominated the song form.

Golden Age orchestras are often told apart by how they combine these. A quick listening guide:

Astor Piazzolla (1921–1992), a bandoneonist who played in Aníbal Troilo's orchestra in the 1940s, studied composition in Paris with Nadia Boulanger in the mid-1950s, who encouraged him to build his music on tango rather than abandon it. Back in Buenos Aires he formed the Octeto Buenos Aires (1955) and later his celebrated quintet of bandoneón, violin, piano, electric guitar and double bass.

His nuevo tango borrowed fugue and counterpoint from Bach and Baroque music, dissonance from 20th-century composers and improvisation and swing from jazz. Pieces such as "Adiós Nonino" (1959), "Libertango" (1974) and the cycle Las cuatro estaciones porteñas are now standard repertoire for classical performers as well as tango bands. In his lifetime traditionalists often rejected his music as not being tango at all — partly because much of it was written for listening, not dancing.

From the late 1990s a third wave, electrotango (or tango electrónico), combined tango samples and live bandoneón with downtempo and lounge electronics. Gotan Project, formed in Paris, made the sound internationally known with the album La Revancha del Tango (2001), and Gustavo Santaolalla's Bajofondo collective did the same from the Río de la Plata. Alongside this, younger orquestas típicas in Buenos Aires and Europe continue to write and record new tangos for dancers.

A starting list that covers the main eras:

• Carlos Gardel — "Mi noche triste", "Volver", "Por una cabeza", "Mi Buenos Aires querido". The essential tango voice.
• Juan D'Arienzo — "La cumparsita" and "El flete": the sound of the 1930s dance boom.
• Carlos Di Sarli — "Bahía Blanca", "A la gran muñeca".
• Aníbal Troilo — "Sur" (with lyrics by Homero Manzi), recordings with Francisco Fiorentino and Roberto Goyeneche.
• Osvaldo Pugliese — "La yumba", "Recuerdo".
• Enrique Santos Discépolo — composer and lyricist of "Cambalache", and the poet behind "Uno" (music by Mariano Mores).
• Astor Piazzolla — "Adiós Nonino", "Libertango", "Balada para un loco" (with Horacio Ferrer).
• Roberto Goyeneche and Susana Rinaldi — interpreters who kept the tango song alive after the Golden Age.
• Gotan Project and Bajofondo — the entry point to electrotango.

For context, start with Gardel, then listen to D'Arienzo and Pugliese playing the same era back to back — the contrast between the two is the fastest way to learn how much range tango has inside a single metre.

Tango sits between Latin American popular song and European concert music, and it is regularly confused with several neighbours:

• Tango vs bolero: both are romantic, minor-key song forms in Spanish, but bolero is Cuban in origin, sung over a gentle guitar-and-percussion pulse, and much smoother; tango is driven by marcato, bandoneón and abrupt accents.
• Tango vs fado: they share the melancholy and the port-city setting, but fado is Portuguese, accompanied by the Portuguese guitar and not written for dancing.
• Tango vs flamenco: flamenco's tangos palo uses guitar, palmas and cante jondo vocals; Argentine tango uses an orchestra built around the bandoneón.
• Tango vs polka and other accordion music: the bandoneón can sound like an accordion to new ears, but tango's minor-key drama and syncopated marcato have nothing of polka's bouncy oom-pah.
• Nuevo tango vs classical and jazz: Piazzolla's concert works are now played by string quartets and symphony orchestras, and many listeners first encounter tango that way.

To an audio model, the strongest tango cue is timbre: the reedy, breathing tone of a bandoneón section, played against pizzicato or legato violins, a dry piano marcato and a slapped bass. Strong beat accents with sudden stops and no drum kit are another clear signal, because most popular music with that much rhythmic drive uses drums.

The weak points are at the edges of the style. Piazzolla's chamber works and string-quartet arrangements contain few typical dance cues; 1920s and 1930s recordings carry surface noise that can hide the instruments; and electrotango puts a programmed beat under the bandoneón.
