Whether amplified or acoustic, bailā music characteristically uses instrumental combinations that include the banjo or mandolin, violin, guitar, rabāna (hand-held frame drum), and a pair of congas. When it involves a solo singer and a chorus, it is known as chorus bailā, a genre brought into prominence via radio by Wally Bastiansz (1913-85). Vāde ("debate") bailā, less common than chorus bailā, calls on performers to extemporize on themes and melodies set by a panel of judges or by the audience)
