Manjira is a small percussion instrument that is commonly used in Indian devotional and folk music. It is also known as cymbals or handbells in English. The Manjira is made of two small metal plates that are struck together to produce a rhythmic jingling sound. It is often used as an accompaniment to other instruments such as the tabla, harmonium, and sitar, and is an important part of many Indian classical and folk music performances.
