Recent research has shown that tepsijanje is still popular, especially with Muslim and Roman Catholic populations in Bosnia and Herzegovina. It is a rare example of a nonmusical object—in this case, a cooking pan—functioning as a musical instrument.
This according to “Examples of an interesting practice: Singing along the pan” by Jasmina Talam, an essay included in Studia instrumentorum musicae popularis. II (Münster: Monsenstein und Vannerdat, 2011 251–56; RILM Abstracts of Music Literature 2011-49486).
Below, two examples of tepsijanje.
