Krivanja (f)
original: кривања
From крив (kriv [bent / crooked]); Bent extension of the chanter, with venthole; Possibly an erroneous spelling (of Krivalja) in Gojković, who oddly refers to Božidar Širola's »Sviraljke s udarnim jezičkom« (Zagreb, 1937), in which this spelling doesn't occur, however.
Gojković, Andrijana: Narodni muzički instrumenti [Folk musical instruments]. Beograd, 1979 (»Širola [129] [?]).
