the torokhkalo () - (kalatalo, torokhkavka, klepach) is a ukrainian folk instrument used in folk ensembles whenever a drum is not available. it was also used by night guards to scare away intruders. the instrument is made from a piece of wood with a handle. a second piece of wood shorter than the first is joined to the original piece by metal rings near from the handle. a hole is drilled through both pieces at one end and a wooden bolt is placed through the hole so that the additional piece can move a small distance. when the instrument is spun around it produces a very loud sound amplified by the stillness of the night.
