The dril-bu (bell) and dorje (scepter) are indispensable liturgical instruments used during Tibetan Buddhist ritual recitation. They are usually regarded as one object, are matched and used together.

These bells have a particularly pure, long sound and can be played around the rim, much like a "singing bowl". They are very responsive to mouth ululation.
