The people of Mazandaran have a rich musical heritage, and tambourine playing, known as "lagan navazi," holds a significant place in their musical customs. It is closely connected to the local life and traditions of the region. In the past, Mazandarani women used copper tambourines for various purposes, both for practical household tasks and as a form of entertainment during social gatherings and celebrations.

Tambourine playing in Mazandaran is not merely a percussion technique but a comprehensive art form. The rhythm and beats played on the tambourine are distinct to the region, reflecting the cultural identity and musical style of Mazandaran. The tambourine players, particularly those with advanced skills, would take the lead in ceremonies and weddings, orchestrating the musical aspect of the events. 

The sound production of the tambourine was also carefully considered by the musicians. The choice of material, size, and shape of the tambourine influenced its sound quality. To enhance the sound, tambourine players would sometimes utilize a small metal tray or plate delicately held by an assistant. This technique added a subtle and resonant quality to the tambourine's vibrations, creating a richer and more captivating musical experience. 

Tambourine playing, accompanied by the traditional Mazandarani dance called "Chekahsema," became an integral part of the festive culture of Mazandaran. It brought joy, rhythm, and a sense of community to various social occasions, fostering a strong bond among the people. Today, the musical custom of tambourine playing continues to be cherished and celebrated in Mazandaran, representing the region's vibrant musical heritage.
