During the instrumental section of sebene, the rhythmic section momentarily recedes, creating an open space for the proliferation of intricate, syncopated guitar refrains. As expounded in John Conteh-Morgan and
Tejumola Olaniyan's "African Drama and Performance", after the ending of the last line of the chorus by singers, "the lead guitarist then kicks off the seben with a guitar rill that is slightly accelerated and is soon joined by the drummer's
snare, the
atalakus marakas (now acting as a rattle), and a random scream from somewhere off-mic". There are five main cadences that characterize sebene: •
Demi-temps (
half-time): Corresponding to the I – IV – I – V progression, this fast-moving sequence gives the sebene a snappy,
upbeat feel and often works well when transitioning from singing into dance sections. • Le
2 temps (two
beats): Corresponding to the I – IV – V – IV progression, is more balanced, with the back-and-forth between the
dominant (V) and
subdominant (IV). •
Le 3 temps (three beats): Based on the I–V–IV–V progression, is a less symmetrical
loop often used to create momentum and variation, with the return to V at the end adding a feeling of anticipation and drive. •
Le 4 temps (four beats): Corresponding to the I–VII–IV–V progression, is richer harmonically, with the inclusion of the VII degree (the "sensible") adding a tense flavor that makes the progression feel more expressive and unexpected. • 7/7: Corresponding to the V–IV progression, is a looped vamp often used in long sebene
jams, where the back-and-forth between the dominant and subdominant provides space for
guitar solos (
mi-solo and solo), or
atalaku shouting to gradually build intensity. The musical beat is delineated through a sequential count akin to a
metronome, typically enumerating as 1, 2, 3, 4, and so forth. In the context of
African music, chord changes, or degree shifts, typically occur every two or four pulses. Although old Congolese rumba pieces from the 1940s-1960s did not feature atalakus, the introduction of the atalaku in 1982, pioneered by
Nono Monzuluku and
Bébé Atalaku of
Zaïko Langa Langa, emerged as a seminal innovation. Throughout the sebene, the atalakus' primary function is to galvanize people to dance, which they achieve through an amalgam of shouts, sung refrains, and vocal embellishments. In addition to vocal exhortations, the atalakus are instrumentalists and dancers, using a shaker to enhance the rhythmic pulse while also intermittently leaving the microphone to join the dance ensemble. == History ==
