What is "krekhts"

Krekhts or krekhtsn (Yiddish for "sobs") are kind of dreydlekh ( ornamentation) in klezmer music, especially on the violin. In an article about Jewish music in Romania, Bob Cohen of Di Naye Kapelye describes krekhts as "a sort of weeping or hiccoughing combination of backwards slide and flick of the little finger high above the base note, while the bow does, well, something - which aptly imitates Jewish liturgical singing style." He also noted that the only other place he has heard this particular ornamentation is in Turkish music on the violin.
