Apala is 20th century percussion and voice music of Yoruba Muslims in Nigeria. This style is typically cited as the most important precursor of the better known fuji music popularized by Sikuru Ayinde Barrister, Ayinla Kollington, Adewale Ayuba and others. But unlike some fuji and all juju music, apala never incorporated any Western instruments and maintains a highly spiritual dimension. One sign of this is the fact that apala singers typically perform while seated.
