Hindu music is a genre of music that has its roots in the Indian subcontinent. It is characterized by its use of ragas, which are melodic scales that provide the framework for improvisation and composition. Raga is a four-letter term used to describe the melodic framework of Hindu music. It is based on a set of rules that govern the use of notes, scales, and rhythms. The ragas are used to create a unique sound that is distinct from other genres of music.
