The lytavry (Ukrainian: Литаври) (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.
