A raga is a melodic framework used in Indian classical music, characterized by a specific set of notes and a unique mood or emotion. Each raga is associated with particular times of day or seasons, influencing the way it is performed and experienced. Musicians use ragas to create improvisational compositions, allowing for personal expression within the established structure. Ragas are built on a scale of five to seven notes, known as swaras. The arrangement and emphasis on certain notes give each raga its distinct identity. Performers often explore the raga's nuances through intricate ornamentation and variations, making each rendition unique while adhering to traditional guidelines.
