I decided to go with Hinduism, which is the religion I was raised with. Hinduism uses Bhajans, which are prayers that are written into song to praise the Gods. They can be done either vocally or with instrumental accompaniment. Usually vocal praise is done at home and in temples there will be instrumental accompaniment. This isn’t for any cultural reason, because, at least in my family, no one plays instruments that would accompany a Bhajan.
The Bhajan I chose is the Hanuman Chalisa, which is meant to sing the prasies of Lord Hanuman. It is sometimes either monophonic or polyphonic, depending on the amount of people there. Singing can be done by anyone. There is also musical accompaniment, a sitar, tabla and harmonium are usually played in any Bhajan.
