Soukous (from French secousse, "shock, jolt, jerk") is a genre of dance music originating from the Democratic Republic of the Congo (formerly Zaire) and the Republic of the Congo (formerly French Congo and the People's Republic of the Congo). It derived from Congolese rumba in the 1960s, with faster dance rhythms and bright, intricate guitar improvisation, and gained popularity in the 1980s in France. Although often used by journalists as a synonym for Congolese rumba, both the music and dance associated with soukous differ from more traditional rumba, especially in its higher tempo, song structures and longer dance sequences.

Soukous fuses traditional Congolese rhythms with contemporary instruments. It customarily incorporates electric guitars, double bass, congas, clips, and brass/woodwinds. Soukous lyrics often explore themes of love, social commentary, philosophical musing, struggle, and success. Singers occasionally performed in Lingala, Kikongo, French and Swahili and bands often consist of a primary vocalist accompanied by several backing singers.

Etymology The term soukous, derived from the French verb secouer, denoting "to shake," initially described a person who moved jerkily but evolved into a dance style synonymous with vitality and cadence. Over time, secousse evolved into soucousses and later soucous in everyday speech and in the press, before the letter "c" was eventually replaced with a "k", giving rise to the modern spelling soukous.

Characteristics The music typically utilizes a time signature and major chords articulated in arpeggiated forms. Soukous lead guitarists are known for their speed, precision, and nimble fingerwork, and often navigate the higher registers of the fretboard. The bassline, inspired by hand-drum percussion patterns, is the genre's rhythmic foundation and is typically characterized by a 16th-note cadence. Emerging prominently during Mobutu Sese Seko's reign in Zaire, the assertive bass style of soukous emulated regimented motions of military marches (marche militaire). This distinctive bass approach involves toggling between lower and higher registers, achieved through a plucking method that employs both the thumb (p) and index finger (i).

Tonally, soukous is shaped by specific configurations in the bass, midrange, and treble frequencies. The bass is generally accentuated by +3 dB to yield a deep, full-bodied low-end that supports the groove. The midrange, especially around the 700 Hz frequency, is often left flat or enhanced by as much as +6 dB. Meanwhile, the treble frequencies are either left flat or attenuated slightly by -3 dB.

In Matonge, the rhythmic guitar typically accompanies mid-tempo vocal passages, with the bass and bass drums accentuating the dominant beats, while guitarists emphasize the offbeats (one and two and three and four and). During vocal performances, the lead guitarist lays down a groove that underpins harmonized call-and-response singing, often intensified by an echo effect, producing an auditory experience sometimes described as a hypnotic auditory experience.

The percussion section is characterized by an unyielding, fast-paced beat, most commonly referred to as cavacha, with the drummer taking the lead in signaling shifts for the guitarists to match the lead player's transitions. Soukous chord progressions mainly rely on the I, IV, and V chords. Common progressions include:

I - I - IV - IV I - IV - V I -I - V-V I - IV/V V/IV - I I/IV - IV/I I - V- I - V V/IV - I

History Origins

The origins of the genre can be traced back to Congolese rumba, which developed in the early 20th century when people in the French Congo and the Belgian Congo began blending intertribal Kongolese maringa dance music around Pool Malebo.

During World War I, new styles of music and dance spread across the Lower Congo region (now Kongo Central) and the Pool Malebo area. These dances developed in labor camps and were also connected to workers returning from the construction of the Matadi–Kinshasa Railway. Local dances such as agbaya and maringa became popular, though the circular agbaya dance was gradually replaced by partnered maringa dancing, which spread widely in Matadi, Boma, Brazzaville, and Léopoldville (now Kinshasa). Early maringa bands used the likembe for melody, a bottle struck with metal rods for rhythm, and a small skin-covered frame drum called patenge for counter-rhythms. By the 1920s, however, accordions and acoustic guitars increasingly replaced the likembe as the main melody instruments. Maringa dancing, known for its hip movements and shifting body weight between the legs, became highly popular. By 1935, partnered dancing had spread throughout much of the Congo basin, including remote villages. Dance halls appeared in towns and villages, although traditional dancing continued in palm-branch huts.

In the early 1940s, Pool Malebo increasingly became a cultural link between Brazzaville and Kinshasa rather than a barrier between the two cities. Cuban son groups such as Sexteto Habanero, Trio Matamoros, and Los Guaracheros de Oriente were broadcast on Radio Congo Belge and became popular across the country.The Encyclopedia of Africa v. 1. 2010 p. 407. Although maringa music was not directly related to Cuban rumba, it gradually became known as "rumba Congolaise" because imported records by Cuban groups were often mistakenly labeled as "rumba". Ethnomusicology professor Kazadi wa Mukuna explained that the name remained popular partly because recording companies reused the term "rumba" while adapting it to local maringa rhythms. The music consequently became known as "Congolese rumba" or "African rumba". Antoine Wendo Kolosoy later became one of the first major stars of Congolese rumba. His 1948 song "Marie-Louise", co-written with guitarist Henri Bowane, became popular across Sub-Saharan Africa. Early pioneers of the genre helped establish Congolese rumba by developing new ways of playing and arranging their instruments.

Formation and paternity debate During the early 1960s, many young Congolese musicians began speeding up the slower tempo of Congolese rumba. Artists introduced faster rhythms and placed greater emphasis on guitar improvisation, especially high-pitched and rapid lead guitar lines imbued with a more heightened African motif. Drummers shifted the clave rhythm to the snare drum, and lead guitars became the central focus of the music.

The origins of soukous are a matter of dispute, with divergent attributions and viewpoints. Clément Ossinondé, a Congolese musicologist specializing in Congolese music, credits Franco Luambo and TPOK Jazz with helping pioneer the style through Franco's fast-paced rumba odemba rhythm. American music journalist Morgan Greenstreet similarly argued that Franco transformed the sebene, which had previously served mainly as a short instrumental bridge between vocal sections, into the central element of Congolese popular music. Franco's odemba style was described as "rougher, more repetitive, and rooted in rhythms that moved the hips of dancers at Kinshasa's hottest clubs". Many musicologists place the origins of soukous in Brazzaville instead of Kinshasa. British music historian Gary Stewart and Ossinondé credit guitarist Jacques Kimbembe and the formation of the Super Band in 1964, later renamed Orchestre Sinza Kotoko, with introducing the soukous style to Brazzaville nightlife around 1966. The group gradually replaced the older boucher style made popular by Les Bantous de la Capitale. Congolese music journalist Audifax Bemba explained that Orchestre Sinza stood out because of its conversational style of singing, expressive lead guitar work that expanded the sebene, and lively rhythm. Kimbembe's guitar style also differed from earlier approaches by doubling notes in eighths rather than following the traditional quarter-note pattern. The band also introduced freestyle dance sections that encouraged energetic audience participation. According to popular stories, their performances were so lively that audiences often began dancing before even entering the venue.

During the late 1960s, Congolese musicians, much like Western artists experimenting with dances such as the twist and the stroll, created a series of new dance styles in order to remain competitive and attract younger audiences. In 1968, Orchestre Sinza Kotoko innovated the genre further with a variation known as mossaka. The band's popularity increased significantly after singer Pierre Moutouari joined them, which led to their first tour in Paris and a recording contract with the French label Pathé Marconi. Around the same period, Docteur Nico introduced kiri-kiri, a dance style partly influenced by the Western jerk dance. Kiri-kiri songs generally followed the standard structure of Congolese rumba before moving into the sebene section, where dancers could perform new dance steps. Docteur Nico's 1968 composition "Kiri-Kiri Mabina Ya Sika" ("kiri-kiri, the new dance"), recorded with Fiesta Sukisa, became the defining anthem of the style. Other groups soon experimented with similar innovations. Les Bantous de la Capitale experimented with hybrids, such as Pamelo Mounk'a's "Masuwa", which was billed as soukous-kiri-kiri. Tabu Ley Rochereau also introduced a dance style known as the jobs, which he described as a blend of the jerk and Congolese rumba. His 1968 song "Martin Luther King", which he dedicated to the assassinated American civil rights leader, exemplified this style. The song stood out for its references to international figures such as Johnny Hallyday and Mao Zedong, its eight-minute length, and its use of a Western-style drum kit, which reflected the gradual obsolescence of older percussion instruments such as maracas. This period saw a proliferation of new dance styles rooted in Congolese rumba, including Jeannot Bombenga's mambenga, Le Grand Kallé's yéké yéké (described as the "eighth phase of the rumba"), and others such as Apollo 11. Reflecting on the rapid musical changes of the period, Docteur Nico later stated, "We invent a new dance style every day". Despite this stylistic diversification, Congolese rumba remained the main foundation of the genre.

During this epoch, the dominant bands in Congolese music included TPOK Jazz, African Fiesta National, African Fiesta Sukisa, and Les Bantous de la Capitale, followed closely by Négro Succès, Conga Succès, and Cobantou. Orchestre Sinza simultaneously emerged as a second-tier orchestra in Congo-Brazzaville that nonetheless became the top-selling African act in the Pathé Marconi catalog from 1969 to 1974. Their innovations played a crucial role in shaping the so-called "third school" of Congolese music, most notably influencing the band Zaïko Langa Langa. In 1974, Zaïko Langa Langa adopted many of Orchestre Sinza's stylistic features, such as a brisk tempo, eighth-note doubling in the sebene, free-form dance, and celebratory rhythms. The sebene in Zaïko Langa Langa's "Éluzam", often cited as the "birth certificate" of the third school, mirrored the sebene from Orchestre Sinza's 1969 track "Vévé".
