The senasel is used in the liturgical music of the Ethiopian Orthodox Church (a sistrum). The clergy will also use a walking stick called a mequamia to keep time. A dawal was originally used in rural churches to summon the devout to prayer. They are constructed from wood or stone slabs. Although qachel can also refer to a little bell, the Beta Israel employ a small gong called a qachel as ritual accompaniment. The Nuer, Anuak, Majangir, Surma, and other Nilotic people all use the toom, a lamellophone. In the South, metal leg rattles are popular. In the Orthodox Christian liturgy, a sizable hand drum called a kebero is played. In secular occasions, smaller kebero drums may be utilized. Although it has a religious function among the Beta Israel, the nagarit, played with a curved stick, is typically used in a secular context, such as royal celebrations or the announcement of proclamations. To Ethiopian Orthodox society, religious music is very essential and plays a big role. Mezmur immediately conjures up images of Ethiopian Orthodox Tewahedo music. Numerous Islamic musical genres have also been impacted by Somali, Djiboutian, and Sudanese cultures. Since the 2000s, when CD sales were at an all-time high, and more recently as a result of digital downloads, Protestant music has also assumed a dominant position.
