Cajun Music

Cajun music is the dance repertoire of the French-speaking Acadian community of southwestern Louisiana. A typical band features diatonic button accordion, fiddle, triangle, acoustic or electric guitar, electric bass and drum kit. The basic groove is a stomping 2/4 two-step or 3/4 waltz at 120-180 BPM, designed for couples on a dance hall floor. Vocals — sung by men or women — use a regional French preserved from 17th-century settlers and laced with English loanwords. Lyrics are concrete: lost love, country life, drinking, family. The button accordion's bellows-driven push-pull patterns and the fiddle's double-stops form the immediately recognizable signature.

The Acadians were French settlers expelled from the maritime provinces of Canada by the British in 1755 (the Grand Dérangement), and many resettled in the marshlands of Louisiana — 'Acadian' eventually softened into 'Cajun.' Through the late 19th and early 20th centuries their fiddle traditions absorbed German-immigrant accordions, blues phrasing from Black Creole neighbors and a swing-band influence from nearby Texas. The first commercial Cajun records — Joseph Falcon and Cleoma Breaux's 'Allons à Lafayette' — appeared in 1928. Postwar players including Iry LeJeune, Lawrence Walker and Aldus Roger anchored the modern style, and the 1970s saw a self-aware revival led by BeauSoleil's Michael Doucet that brought Cajun music to international stages.

The diatonic accordion is a one-key instrument: push and pull produce different notes, so its riffs have an unmistakable rocking quality. The triangle, played by hand with a steel beater, sits on the upper half of the bar and locks the dancers to the beat. Note how the fiddle and accordion often play in slightly different intonation — neither tempered to a piano nor entirely to each other — which gives the music its plaintive edge. Lyrics use a Louisiana French quite distinct from Parisian French.

For the postwar classic sound, Iry LeJeune's 1950s recordings (collected on 'The Definitive Collection') remain the benchmark. For the revival, try BeauSoleil's 'L'amour ou la folie' (1997) or Steve Riley & The Mamou Playboys' 'La Toussaint' (1995).

The button accordion only entered Cajun music around 1900, brought by German Jewish merchants, and was initially resented by traditional fiddlers before becoming the genre's defining sound. The famous 'Dueling Banjos' sequence from the film 'Deliverance' (1972) is a bluegrass tune, not Cajun — a confusion the Louisiana scene has been gently correcting for fifty years.
