A line is sung by a (SOLOIST) or small group of singers, and the entire group (CHORUS) responds in turn (typically with a predetermined REFRAIN), simulating a "musical conversation" with the "lead singer." The soloist frequently improves. Male and female vocalists in Africa frequently "shout words" (VOCABLES) and enjoy using their highest vocal register, known as the FALSETTO. African singing can be accompanied by instruments or performed solo (A CAPPELLA).
