Libertango, explained

Piazzolla recorded Libertango in Milan in 1974. Here is what the title means, how it is built, why it took over, and what makes it hard to play well.

Milan, 1974

Piazzolla was 53, recovering from the heart attack he had suffered in 1973, and had moved to Italy partly for his health and partly because Argentina had become exhausting in every sense. He recorded the album Libertango in Milan in 1974 with Italian session players, produced by Aldo Pagani, and it does not sound much like the quintet records around it. There are electric bass, drums, organ and layered strings on it. It is, unmistakably, a 1970s European studio record.

The title fuses libertad and tango, and it is generally read as a statement of independence: from the traditional tango establishment that had spent twenty years telling him he was wrong, and from Argentina itself in a period when the country was sliding toward the 1976 coup. He did not write a manifesto about it. He wrote a riff.

What the piece is actually made of

Structurally it is close to minimal. A one-bar ostinato in A minor, articulated in the 3-3-2 grouping, repeats almost without break for the entire piece. Over it, a melody in long notes enters, climbs, and repeats in higher registers with the texture thickening underneath. There is no development section, no modulation to speak of, and no real contrast. It gets louder and denser and then it stops.

This is exactly why it works. The ostinato is physical — it makes people move their heads before they have decided to like the music — and the melody is wide-intervalled and slow enough to sing over the top of the churn. It is arguably the most efficient thing Piazzolla wrote: everything that made his style recognisable, and nothing that made it difficult.

It is worth saying that the harmony is barely more elaborate than the form. The bass moves through a short minor cycle and returns; there is no key change and no surprise chord anywhere in the piece. Piazzolla could write dense harmony when he wanted to, and here he simply declined to, which is a compositional decision rather than an oversight.

How it escaped

The piece became a standard through cover versions rather than through the original. The biggest single push came in 1981, when Grace Jones released I've Seen That Face Before (Libertango) on Nightclubbing, setting new lyrics and a dub-tinged arrangement over Piazzolla's riff. That put the tune in front of an audience with no idea who had written it.

After that it spread everywhere: Yo-Yo Ma's 1997 album Soul of the Tango, the Bond and Vanessa-Mae school of amplified string playing, countless film and advertising placements, figure-skating programmes, and — the version most people have now heard without knowing its name — the arrangement that appears in Studio Ghibli's 1995 film Whisper of the Heart. Today it is a set piece for every instrument that exists, including some that should not attempt it.

Why it is harder than it looks

On paper Libertango is four chords and a riff, which is why every amateur ensemble programmes it and why so many performances are dull. The difficulties are all in execution.

First, the ostinato must be metronomically even and rhythmically savage at the same time. Any drift and the piece sags; any politeness and it stops being tango. Second, the melody has to fight the ostinato rather than float on it — it should feel like someone talking over a machine, late on some entries and cutting others short. Third, since the written material never changes, the entire shape of the performance is the players' responsibility: register, density, dynamics and one genuine climax. If a group just plays the notes from the top, the piece is repetitive, and the audience is right.

The other trap is speed. It is frequently played too fast, which turns the ostinato into a blur and removes the space the melody needs to lean. Piazzolla's own tempo is more patient than most covers.

Finally, the ending is a judgement call. The studio original fades; a live performance cannot. Most groups stop dead on the ostinato, which is the cleanest solution, and a few add a ritardando, which usually sounds apologetic after four minutes of machinery.

Two instruments, one riff

It reduces well. The ostinato lives naturally in a double bass, which can give it weight and a percussive edge no keyboard bass matches, leaving the accordion to carry the melody and add the inner harmony. That split is close to the original division of labour between the bass, guitar and bandoneon, and it is the version we play most often at events in Singapore — usually as the piece that makes a talkative room stop talking.

If you are learning it, start with the ostinato alone at half tempo with a metronome and get the 3-3-2 accents brutal and identical every bar. The melody is the easy part. The riff is the piece.

Frequently asked

What does Libertango mean?

It is a compound of the Spanish libertad, meaning liberty, and tango. Piazzolla recorded it in 1974, and the title is usually understood as marking his break from traditional tango and from the Argentine musical establishment that had opposed his work, as well as his move to Europe at a dark political moment.

When did Piazzolla write Libertango?

He composed it in 1973 or early 1974 and recorded it in Milan in 1974 as the title track of the Libertango album, made with Italian session musicians after his move to Italy. The piece was written during his recovery from a heart attack suffered in 1973.

Why is Libertango so popular?

It has a repeating, physically infectious minor-key riff, a broad singable melody, and almost no structural complexity, so it transfers to any instrument or line-up. Grace Jones's 1981 vocal version and Yo-Yo Ma's 1997 recording carried it far beyond tango audiences, and film and advertising have kept it in circulation since.
