Tresillo (rhythm)

In sub-Saharan rhythm, the four main beats are typically divided into three or four pulses, creating a 12-pulse (¹²
₈), or 16-pulse (⁴
₄) cycle.[3] Every triple-pulse pattern has its duple-pulse correlative; the two pulse structures are two sides of the same coin. Cross-beats are generated by grouping pulses contrary to their given structure, for example: groups of two or four in ¹²
₈ or groups of three or six in ⁴
₄.[4] The duple-pulse correlative of the three cross-beats of the hemiola, is known in Afro-Cuban music as tresillo. The pulse names of tresillo and the three cross-beats of the hemiola (3:2) are identical: one, one-ah, two-and.[5]

The composite pattern of tresillo and the main beats is commonly known as the habanera,[6] congo,[7] tango-congo,[8] or tango.[9] The habanera rhythm is the duple-pulse correlative of the vertical hemiola (above). The three cross-beats of the hemiola are generated by grouping triple pulses in twos: 6 pulses ÷ 2 = 3 cross-beats. Tresillo is generated by grouping duple pulses in threes: 8 pulses ÷ 3 = 2 cross-beats (consisting of three pulses each), with a remainder of a partial cross-beat (spanning two pulses). In other words, 8 ÷ 3 = 2, r2. Tresillo is a cross-rhythmic fragment. It contains the first three cross-beats of 4:3.[10]

The Cuban contradanza, known outside of Cuba as the habanera, was the first written music to be rhythmically based on an African motif (tresillo and its variants). Tresillo is used as an ostinato figure in the left hand. The habanera was the first dance music from Cuba to be exported all over the world. Because of the habanera's global popularity, tresillo and its variants are found in popular music in nearly every city on the planet. Later, Cuban musical exports, such as the son, son montuno, and the mambo continued to reinforce the use of tresillo bass lines and vamps.

Composer Sebastián Iradier

"La Paloma" (1863) is one of the most popular habaneras, having been produced and reinterpreted in diverse cultures, settings, arrangements, and recordings over the last 140 years. The song was composed and written by Spanish composer Sebastián Iradier (later Yradier) after he visited Cuba in 1861. In the excerpt below, the left hand plays the tresillo rhythm.

As used in Cuban popular music, tresillo refers to the "three-side" (first three strokes) of the son clave pattern.[11]

Although the triplet divides the main beats by three pulses (triple-pulse) and tresillo divides them by four pulses (duple-pulse), the two figures share the same pulse names: one, one-ah, two-and.[12] The common figure known as the habanera consists of tresillo with the second main beat.

The cinquillo pattern is another common embellishment of tresillo. Cinquillo is used frequently in the Cuban contradanza (the "habanera") and the danzón. The figure is also a common bell pattern found throughout sub-Saharan Africa.

Tresillo is the rhythmic basis of many African and Afro-Cuban drum rhythms, as well as the ostinato bass tumbao in Cuban son-based musics, such as son montuno, mambo, salsa, and Latin jazz.[13][14] The example below shows a tresillo-based tumbao from "Alza los pies Congo" by Septeto Habanero (1925).

African American music began incorporating Afro-Cuban rhythmic motifs in the 1800s with the popularity of the Cuban contradanza (known outside of Cuba as the habanera). The habanera was the first written music to be rhythmically based on an African motif (1803).[17] Musicians from Havana and New Orleans would take the twice-daily ferry between both cities to perform and not surprisingly, the habanera quickly took root in the musically fertile city of New Orleans. The habanera was the first of many Cuban music genres which enjoyed periods of popularity in the United States, and reinforced and inspired the use of tresillo-based rhythms in African American music.[18]

From the perspective of African American music, the habanera rhythm can be thought of as a combination of tresillo and the backbeat.[19]

Tresillo in African American music is one of the clearest examples of African rhythmic retention in the United States.[20] There are examples of tresillo-like rhythms in a few African American folk musics such as the foot stomping patterns in ring shout and the post-Civil War drum and fife music.[21] Tresillo is also heard prominently in New Orleans second line music. Wynton Marsalis considers tresillo to be the New Orleans "clave", although technically, the pattern is only half a clave.[22]

John Storm Roberts states that "the habanera reached the United States 20 years before the first rag was published."[23] Scott Joplin's "Solace" (1909) is considered a habanera. For the more than quarter-century in which the cakewalk, ragtime and proto-jazz were forming and developing, the habanera was a consistent part of African American popular music.[24] Ned Sublette postulates that the habanera rhythm "found its way into ragtime and the cakewalk",[25] while Roberts suggests that "the habanera influence may have been part of what freed black music from ragtime's European bass."[26]

Jelly Roll Morton

Early New Orleans jazz bands had habaneras in their repertoire and the tresillo/habanera was a rhythmic staple of jazz at the turn of the 20th century. For example, "St. Louis Blues" (1914) by W.C. Handy has a tresillo bass line. Jelly Roll Morton considered the tresillo/habanera (which he called the Spanish tinge) to be an essential ingredient of jazz. Morton stated, "Now in one of my earliest tunes, "New Orleans Blues", you can notice the Spanish tinge. In fact, if you can't manage to put tinges of Spanish in your tunes, you will never be able to get the right seasoning, I call it, for jazz."[27] An excerpt of "New Orleans Blues" is shown below. In the excerpt, the left hand plays the tresillo rhythm, while the right hand plays variations on cinquillo.

James P. Johnson's influential "Charleston" rhythm is based on the first two strokes of tresillo. Johnson said he learned the rhythm from dockworkers in the South Carolina city of the same name. Although the exact origins of jazz syncopation may never be known, there is evidence that the habanera/tresillo was there at its conception. Buddy Bolden, the first known jazz musician, is credited with creating the big four, a tresillo/habanera-based pattern. The big four was the first syncopated bass drum pattern to deviate from the standard on-the-beat march.[28] As the example below shows, the second half of the big four pattern is the habanera rhythm.[29]

In Early Jazz; Its Roots and Musical Development, Gunther Schuller states:[30]

It is probably safe to say that by and large the simpler African rhythmic patterns survived in jazz ... because they could be adapted more readily to European rhythmic conceptions. Some survived, others were discarded as the Europeanization progressed. It may also account for the fact that patterns such as [tresillo have] ... remained one of the most useful and common syncopated patterns in jazz.

Dave Bartholomew in 1977

In the late 1940s, R&B music borrowed tresillo directly from Cuban music.

New Orleans producer-bandleader Dave Bartholomew first employed this figure (as a saxophone-section riff) on his own 1949 disc "Country Boy" and subsequently helped make it the most over-used rhythmic pattern in 1950s rock 'n' roll. On numerous recordings by Fats Domino, Little Richard and others, Bartholomew assigned this repeating three-note pattern not just to the string bass, but also to electric guitars and even baritone sax, making for a very heavy bottom. He recalls first hearing the figure – as a bass pattern on a Cuban disc.

— Palmer (1995)[31]

In a 1988 interview with Robert Palmer, Bartholomew revealed how he initially superimposed tresillo over swing rhythm.

I heard the bass playing that part on a 'rumba' record. On "Country Boy" I had my bass and drums playing a straight swing rhythm and wrote out that rumba bass part for the saxes to play on top of the swing rhythm. Later, especially after rock 'n' roll came along, I made the 'rumba' bass part heavier and heavier. I'd have the string bass, an electric guitar and a baritone all in unison.

— Palmer (1988)[32]

Bartholomew referred to son by the misnomer rumba, a common practice of that time. On Bartholomew's 1949 tresillo-based "Oh Cubanas", we clearly hear an attempt to blend African American and Afro-Cuban music.

Fats Domino's "Blue Monday", produced by Bartholomew, is another example of this now classic use of tresillo in R&B. Listen: Fat's Domino's "Blue Monday" (1956). On Bartholomew's 1949 tresillo-based "Oh Cubanas" we clearly hear an attempt to blend African American and Afro-Cuban music. In his composition "Misery" (1957), New Orleans pianist Professor Longhair (Henry Roeland Byrd) plays a habanera-like figure in his left hand.

The bass line on Elvis Presley's 1956 "Hound Dog" is perhaps the most well known rock 'n roll example of the tresillo rhythm pattern.

The first jazz standard composed by a non-Latin to play off of the correlation between tresillo and the hemiola, was Wayne Shorter's "Footprints" (1967).[33] On the version recorded on Miles Smiles by Miles Davis, the bass switches to tresillo at 2:20. This type of African-based rhythmic interplay between the two pulse (subdivision) structures, was explored in the 1940s by Machito's Afro-Cubans. Those structures are accessed directly by Ron Carter (bass) and Tony Williams (drums), via the rhythmic sensibilities of swing. Throughout the piece, the four beats, whether sounded or not, are maintained as the temporal referent.

In the example below, the main beats are indicated by slashed noteheads. They are shown here for reference and do not indicate bass notes.

Mongo Santamaria used the tresillo bass pattern in his 1958 jazz standard “Afro Blue”.
