The music

What the clave tells you (and what it doesn’t)

The clave is the two-bar pattern a salsa band is built on. It can pin down the 1, but only once you know which way it runs, and that turns out to be the hard part.

Short answer

Son clave is a five-stroke pattern that repeats every two bars: three strokes on one side, two on the other. In 3-2 clave the first stroke lands on the 1. In 2-3 clave the first stroke is on 2, so the 1 is the silent beat just before the two straight strokes. Which way a song runs is set by its melody and phrasing, and research shows that hearing it takes salsa-specific experience.

Five strokes, two sides

The clave is a rhythm and also the name of the two wooden sticks that often play it. It’s five strokes spread over two bars, with three strokes on one side and two on the other [Berklee; University of Puget Sound; Smithsonian Folkways]. Salsa uses the son clave. The rumba clave differs by one stroke: the last stroke of the three-side moves half a beat later [Berklee].

What makes it more than a rhythm is that everything else is arranged around it. The other parts have to “fit the clave” to sound right, and breaks and stops fall in clave too [Smithsonian Folkways]. It’s also often not played out loud at all. It’s implied, and it still drives the groove [Smithsonian Folkways].

3-2 and 2-3, in dancer counts

The two directions are the same pattern started from different halves. Counted the way dancers count, across eight beats:

  • 2-3: 2, 3, 5, 6& and 8. Nothing on the 1.
  • 3-2: 1, 2&, 4, 6 and 7. The first stroke lands on the 1.

In 3-2, the first stroke is on the 1. In 2-3 there is nothing on the 1: the pattern starts on 2 [DanceInTime; GO Latin Dance]. SalsaCoach’s recorded band is in 2-3, and when we measured it, its clave struck exactly 2, 3, 5, the “and” of 6, and 8.

Who decides the direction? The song.

You can’t tell 2-3 from 3-2 by listening to the clave alone, because on a loop it’s the same pattern. The direction is set by the song: where its melody and phrases start relative to the pattern. Kevin Moore puts it as “direction is relative while clave alignment is absolute” [via Wikipedia]. The researchers who tested listeners concluded the 2-3/3-2 difference is a convention learned through exposure and training, not something inherent in the sound [Getz, Barton & Kubovy 2014].

The terms themselves are younger than the music. “3-2” and “2-3” were developed in 1940s New York, around Mario Bauzá and Machito’s Afro-Cubans, and many Cuban musicians don’t talk about clave this way at all [Peñalosa, via Wikipedia].

Why it’s a hard first cue

Because hearing a song’s direction is an expert skill. In a study published in 2014, listeners who didn’t know salsa couldn’t match recordings to the right clave; listeners with some musical training or some familiarity heard that the music needed a syncopated pattern but still couldn’t pick the right one. Only musicians well acquainted with salsa got it right [Getz, Barton & Kubovy 2014]. A 2021 follow-up found that both training and exposure had to be specific to salsa [Getz, Barton & Perry 2021].

There’s a practical problem too. In a 2-3 song the clave is silent on the 1 and its three-stroke side starts on 5, which makes it easy to hear 5 as 1. That’s exactly what SalsaCoach’s own band does, and it’s why the app points beginners to the bell first.

How it still helps

Once you know a song’s direction, the clave locks the count in place, because everything else is built on it. For On2 dancers it helps directly: the two-side’s first stroke always lands on the second beat of its bar, which is count 2 in a 2-3 song and count 6 in a 3-2 song, so one of your two breaks always lands with a clave stroke. The two teachers who systematized New York On2, Eddie Torres and Angel Rodríguez, both teach students to find the 2 by listening for the clave and the conga slap [Hutchinson 2004].

It also matters culturally. Sydney Hutchinson’s interviews with dancers in Puerto Rico found that most of them think of and teach the dance to the clave rather than to counts [Hutchinson 2004, note 12]. Some teachers argue the other way for beginners, and recommend the conga’s pattern as a steadier reference than a clave that often isn’t played [Son y Casino].

Practise hearing it

The Smithsonian’s salsa lesson has students clap the implied clave along with a recording, then walk the steady beat while they clap it [Smithsonian Folkways]. You can do the same with SalsaCoach’s band below: start with the clave and the bell together, so the clave has something steady to sit against, then mute the bell and keep the count going.

  • Clave: plays on 2, 3, 5, 6& and 8; silent on 1, 4, 6 and 7.
  • Campana (bell): plays on 1, 2, 3, 4, 4&, 5, 6, 6&, 7, 8 and 8&.

Questions

Is every salsa song in 2-3?

No. Songs come in both directions, and a song can shift its alignment between sections. The direction belongs to the song, not to salsa.

Does the clave always play?

No. It’s often implied rather than played out loud; the other instruments are arranged around it either way.

Son clave or rumba clave?

Salsa uses son clave almost exclusively. Rumba clave moves the last stroke of the three-side half a beat later.
