Iranian music is a rich and diverse tradition that spans thousands of years, reflecting the country's varied cultures and histories. It includes both classical and folk styles, with instruments like the tar, setar, and santur playing significant roles. Persian poetry often accompanies the music, enhancing its emotional depth and cultural significance. The classical genre, known as Persian classical music, is based on a system of modes called dastgah. This music is typically performed in small ensembles and emphasizes improvisation. In contrast, folk music varies by region, showcasing local instruments and themes, and is often passed down through generations, preserving the cultural heritage of the Iranian people.
