Cross-rhythm drumming is a part of Ewe musical culture. In general, Ewe drums are constructed like barrels with wooden staves and metal rings, or carved from a single log. They are played with sticks and hands, and often fulfill roles that are traditional to the family. The 'child' or 'baby brother' drum, kagan, usually plays on the off beats in a repeated pattern that links directly with the bell and shaker ostinatos. The 'mother' drum, kidi, usually has a more active role in the accompaniment. It responds to the larger sogo or 'father' drum. The entire ensemble is led by the atsimevu or 'grandfather' drum, largest of the group.
