Lytavry
The lytavry () (also tulumbasy) are a bass drum similar to the kettle drums or timpani used in Ukraine. The lytavry were used in Ukraine from the times of the Cossacks, and probably earlier as a signaling device to announce meetings and enemy attacks. They are used in Ukrainian folk instrument orchestras. Hornbostel-Sachs classification number 211.11
