Ragam is a term used in Indian classical music to describe a melodic framework for improvisation and composition. Each ragam consists of a specific set of notes, known as swaras, and has its own unique mood or emotion, often associated with different times of the day or seasons. Ragam serves as the foundation for various musical forms, including khayal and dhrupad. Musicians use ragams to create intricate melodies, allowing for personal expression while adhering to traditional rules. The study of ragam is essential for understanding the rich heritage of Indian music.
