Traditional Yoruba drums (also known as IGBIN / AGBA / IGBE / ILU OSUGBO) played with straight sticks and hand, producing strong deep tones.
Used in traditional religious settings or for kings and dignitaries. Played singularly or in sets of two up about to seven, they are often painted and/or feature elaborate body carvings.
They vary greatly in size - the largest Gbedu is made from a whole tree trunk - as can be seen in Fela Kuti's (and now Seun Kuti's) Egypt 80 band and also in the Kalakuta museum.
