This nankasa drum is a Ugandan drum made from hide and hardwood, with modern versions being made with pinewood. It is generally associated with the Baganda of Uganda. It is part of the Ganda drum ensemble. The embuutu is played with the hands, which differentiates it from the larger namunjoloba, which is played with drumsticks. The nankasa is also played with sticks rather than beaten with hands like the other drums and it makes a high-pitched sound.
Traditionally drums were used not just to accompany music-making or dance, but also in tribal communities to communicate simple messages between nearby villages, or to call people together for some group activity. Churches would use massive drums to call their congregations to church.
