Each raaga consists of a specific set of notes and rules for how those notes can be used, creating a unique mood or emotion. Raagas are often associated with different times of day or seasons, enhancing their expressive qualities. Performers of Hindustani Raaga use improvisation within these frameworks, allowing for personal interpretation while adhering to traditional guidelines. Instruments like the sitar, sarod, and tabla are commonly used in raaga performances, showcasing the intricate interplay between melody and rhythm.
