Idiophones – Struck Idiophones – Slit Drum

The kentongan is a slit drum idiophone that comes from Central Java, Indonesia.  These slit drums were used in traditional villages as a security system.  Specific patterns were played to communicate to others who were on duty patrolling the village, which gave a sense of security to village residents at nighttime.  They were usually hung vertically from security posts or village halls, but they could also rest horizontally as seen here.  In addition to being an alarm system, they were used to signal residents to gather for help in the village, or to send the signal that prayers will soon start.  The kentongan also functioned as a musical rhythmic instrument accompanying the angklung (a bamboo pitched instrument) and the suling (flute).

As seen in this collection there is a variety of uses, shapes and materials used for the kentongan from the Indonesian regions.
