A dastgah is a system of musical modes used in Persian classical music. Each dastgah serves as a framework for improvisation and composition, providing a unique emotional atmosphere. There are several dastgahs, each with its own distinct set of notes and characteristic melodies, allowing musicians to express a wide range of feelings and stories. Musicians often perform dastgahs using traditional instruments like the tar or setar, which enhance the intricate sounds. The beauty of dastgahs lies in their flexibility; artists can explore and create variations while staying true to the essence of the mode, making each performance a unique experience.
