Congolese rumba — the Kinshasa/Brazzaville dance-band style of the 1950s–70s (Franco and OK Jazz, Le Grand Kallé, Tabu Ley), born from Cuban son records and later sped up into soukous.
How it sits: mid-tempo and unhurried. The guitar layer is a composite of the two interlocking guitars: the rhythm (mi-solo) guitar picks low chord tones on the beats, the lead answers with high notes on the off-beats and a sixteenth pickup. Maracas (shaker) run eighths with the off-beats leaning, conga slaps on 2 and plays open tones on 4 and and of 4, and the bass sits root–fifth–octave under a I–IV–V–I cycle.
Listen for the two guitar registers locking into one continuous line — neither guitar plays the whole pattern.
Practice: play only the low notes, then only the high ones, then both; hear how the off-beat lead pulls the groove forward.
