The musical genre of India is known as Raga, which is a four letter word. Raga is an ancient form of Indian classical music that has been around for centuries. It is based on melodic modes and is characterized by improvisation and modulation. Raga is traditionally performed with instruments such as the sitar, tabla, and sarangi. It is often accompanied by singing and chanting, and is used to express emotions and tell stories. Raga is an important part of Indian culture and is still widely practiced today.
