The term "Dastgah" refers to a system of musical modes used in traditional Persian music. Each dastgah serves as a framework for improvisation, allowing musicians to express emotions and tell stories through their performances. There are several dastgahs, each with its unique character and mood, influencing the choice of instruments and melodies. In a typical performance, musicians may explore a dastgah by starting with a specific melody, known as a gousheh, and then elaborating on it through improvisation. This practice highlights the creativity and skill of the artist, making each performance a unique experience that reflects the rich cultural heritage of Iran.
