The reverberating sound of the bowed mono-string pena is an integral part of all the famous festivals held in Manipur, including the Lai Haraoba festivals. This indigenous stringed instrument is also known as bena in parts of Assam. It has two parts  the penamasa and the pena cheijing. Earlier used to invoke the gods, today it is used in all kinds of performances, including music concerts. The musical instrument is synonymous with Manipur and is also the oldest musical instrument of the Metei group of people. The instrument finds its use in folk music, solo and group musical performances and even as an accompanying instrument for the classical Manipuri dance. The nagas call it tingtelia and it is also played in some parts of Bangladesh.
