Compas, also known as Compas direct in French, or konpa dirèk in Creole or simply konpa is a modern méringue, the national music genre of Haiti that people have been dancing and singing since the 1800s. Popularized by Haitian sax and guitar player Nemours Jean-Baptiste in 1955, compas is the main music of many countries such as Dominica and the French Antilles, etc.Whether it is incorrectly called zouk where French Antilles artists of Martinique and Guadeloupe have taken it or compas in places where Haitian artists have toured, this méringue style is very influential in the Caribbean, Africa, Cape Verde, Portugal, France, part of Canada, South and North America.

Compas direct is a modern méringue popularized in 1955 by the Nemours Jean Baptiste, a Haitian sax and guitar player. Nemours Jean-Baptiste presented his orchestra “Ensemble Aux Calebasses” in 1955 (named after the club “Aux Calebasses” located at Carrefour, a western neighborhood of Port-au-Prince; Haiti's capital where the band used to perform on weekends). Compas popularity took off likely due to the genre's ability to improvise and hold the rhythm section steady. Jean-Baptiste incorporated a lot of brass and easily recognized rhythms. Compas music is sung in Creole, English, Spanish, French, Portuguese, etc. Nemours' popularity grew in and out of the country. Its clean horn section was remarkable and the band featured méringue tunes that gained instant popularity.

Cadence rampa (also known as kadans ranpa in creole or simply kadans) is a modern Haitian méringue, popularized by the virtuoso sax player Webert Sicot in the early 60s. Sicot left Nemours Jean-Baptiste compas music band and called his music cadence to differentiate it from konpa especially when he took it abroad, however, either one is the same modern méringue. Only rivalery between Sicot and Nemours created these names.

As early as the late 50s Nemours and the Sicot Brothers from Haiti would frequently tour the Caribbean, especially Dominica and the French Islands of Martinique & Guadeloupe to spread the seed of the méringue-cadence.

Webert Sicot, the originator of cadence recorded three LPs albums with French Antilles producers: two with "Celini disques" in Guadeloupe and one with "Balthazar" in Martinique. In addition to the Sicot brothers, almost all existing Haitian compas bands have toured these Islands that have since adopted the music and the dance of the méringue. For example, in Martinique, several music groups: Ensemble Abricot (bienvenue, festival compas), les djoubap's (Isabelle), combo jazz (electronique compas, pa gadem sou cote), Georges Plonquitte (vini dance compas direct), etc. have all within a year conquered the public with the many tunes or compositions of Nemours. Haitian compas and cadence bands were asked to integrate Antillean musicians. Consequently, the leading "Les Guais troubadours", with influential singer "Louis Lahens" along other bands, played a very important role in the schooling of Antilleans to the méringue compas or kadans music style. Later Nemours became a favorite of Dominican president, Joaquín Balaguer who often contracted the band. This is why hits like "ti Carole", "Chagrin d'amour" featured by known Dominican stars Luis Miguel and others are also sung in Spanish.

The dance-style that accompanied konpa dirèk in the 1950s, was a two step dance called kare (square). As a méringue, a ballroom dance, konpa is danced in pair. Sometimes partners dance holding each other tightly and romantically; in this case often most of the moves are made at the hips.

The mini-jazz movement started in the mid-1960s, small bands called mini-djaz (which grew out of Haiti’s light rock and roll yeye bands of the early 1960s) played konpa featuring paired electric guitars, electric bass, drumset and other percussion, often with a saxophone. This trend, launched by Shleu Shleu after 1965, came to include a number of groups from Port-au-Prince neighbourhoods, especially the suburb of Pétionville. Tabou Combo, Les Difficiles, Les Loups Noirs, Les Frères DéJean, Les Fantaisistes de Carrefour, Bossa Combo and Les Ambassadeurs (among others) formed the core of this middle-class popular music movement.

From 1968 to the 1970s prominent bands like Bossa Combo, Les Shleu Shleu, Les Ambassadeurs, Les Vickings, Les Fantaisistes, Les Loups Noirs, Les Freres Dejean, Les Difficiles, Les Gypsies and mostly the majestic Tabou Combo have exerted a dominance on the Caribbean and many places in Europe and South America musical scene. For example, Tabou Combo has remained on the Paris hit parade for weeks with its "New York City" hit. Tabou did filled New York Central park in the same period. Guitar based mini-jazz like Les Difficiles and Gypsies influenced many flamenco artists. The guitar was the king instrument.

These young Haitian mini-jazz musicians were critical in the creation of new technics that contribute to the fancyness of the style. Although Raymond Guaspard (Nemours) had already started it in the 50s, however, guitar players such as Corvington (Les Corvington), Serge Rosenthal (Shleu Shleu), Ricardo/Tiplum (Les Ambassadeurs), Robert Martineau (Les Difficiles/Gypsies/Scorpio/Topvice…), Dadou Pasket (Tabou combo/Magnum Band), Jean Claude Jean (Tabou Combo/Super Star…), Claude Marcellin (Les Difficiles/D.P. Express/Zèklè…), Police Nozile (Les Frères Déjean/D.P. Express…) and many more have created intricate mostly rhythmic guitar styles that constitute a strong distinguishable feature of the méringue.

The new generation was a moment of experiment with the MIDI technology. In the mid 80s French Antilles Kassav', which music repertoire is 90% compas music was the first in the Caribbean to apply the MIDI technology, already in use in pop and rock bands, to compas. In the late 80's, After pianist/keyboard wizard Robert Charlot Raymonvil came out with Top Vice, young Haitian music groups applied the MIDI technology that reduced the band's size and offered a variety of new sounds. They were called compas nouvelle génération; however, most of them later, along with many other musicians in the world, went back to a full band with live instruments. The new generation was a moment of experiment with the MIDI technology. Popular new generation bands were Zin, Phantom, Lakole, Papash and a few more. Phantom was the first to return to a full band in less than two years while Zin, Lakol and Papash have continued with the MIDI without a live horn section.

In the early 2000, several compas bands such as Carimi, T-Vice, Top Vice, and Zeglen toured the French Antilles as usual with success. The singer Vro who sang in duet with Robert Charlot on her album Softcore and many other Antillean artists have adopted this light compas style, which is more popular in France and the Caribbean. The compas' fine guitar lines with the chorus and other synthesizer effects is being heard now in zouk, the French Antilles compas music. For example, French Antilles singer Tanya St. Val who has collaborated with many great Haitian compas artists like Alan Cavé, Dadou Pasket from the great Magnum Band, etc. is very close to this style. The beauty of this is that these compas lands influence one another with nice chorus, guitar lines, female voices…within the team up of the conga-drum-cowbell.

Cape Verdean, Caribbean and African artists usually feature one another via compas songs. A review of several CDs from African, Cape Verdean, French Antilles and Haitian artists shows many similarities.
