a) Iya ilu (the mother drums)
b) Omele (the baby drums)

The bottom (idi ilu) of the cone shaped iya ilu bata is played with an open palm. A beater plays the high pitched smaller end (sasa). Ida, a thick black substance, is affixed to the bottom, making it possible to play different pitches from this side of the drum.

The omele genus comprises:

(i) Omele ako (male backing drum)
Three small bata with three basic speech tuned tones. Omele ako, adamo, and . These three drums are tied together and are played by one drummer using two flat leather beaters.

(ii) Omele abo (female backing drum)
This is a smaller version of the iya ilu.

As with the dundun ensemble, the bata family is usually enlarged by increasing the number of drums and players.
